      2:09 backpedaling issue is solved by thinning out the thickness of the right rear dropout by use of a spinning grinder, a thinner dropout improves the farthest distance of the biggest cog to the chainring, they do this with the brand Sride 1x12, its a bit tedious metal work but effective or it may be solved if the chainring can be be moved inward further if possible without thinning the bottom bracket shell,

      4:17 and 8:22 problems are apparent for weaker riders, 1x drivetrain is for bikers who can also do jogging on the mountains, sufficient stamina to compensate for the lack of gears, and stronger riders can use smaller cogs not to inflict friction on the chain from using huge cogs

    • @johnnyboy3357
      @johnnyboy3357 3 года назад +1

      8:58 is basically logical from the get go, bending the chain by using a single chainring really wears down the chain faster, i wonder if manufacturers used a special mix of metals for the chain specifically made for 1x setup, it should be supple but at the same time rigid enough not to stretch quickly, maybe because Shimano charges more on their price tag because of that physical characteristic of their chain, but since its only logical to perceive that problem, instead, i decided to downgrade the cassette sprocket down to 8 speed only to be gentle on the chain and use my stamina to compensate for the losses, in 34t ring, it is as if im climbing a steep gradient using a compact road crank of 50/34 only without the 50t and a sprocket not exceeding 42t 8speed, it depends on the track, if there are short changes to the gradient i use 1x, if the gradient change is long enough i use a bike that has a semi 1x, its actually a 2x but only without using a front derailleur, the seat tube is empty, just tough it out for the time loss only to get rid of that front derailleur lol

    From someone inside the industry.... The reason the industry pushed you into this. 1. Fewer parts to inventory and buy for manufacturing and warehousing for warranty and replacment sales. 2.Fewer parts that needed enginering and design year after year on the bikes drive train . 3.The fewer steps and faster assymbly results in labor savings in all aspects of bike manufacturing from spec., purchasing, warehousing, assymbly, packaging, shipping cost due to lower weight and more. 4. 1x opened up more options for suspension and frame design that again reduced cost of manufacturing.
    You were pushed into 1x not for your riding benifit but for greater profitability of the manufacture.

      Well, to be honest, the triple was in itself a workaround for getting that insane gear range while engineers didn't quite figure out how to get the range solely on cassette with reliable shifting. SRAM was simply the first to realize/remember about that and jumped the gun.

    I've been using 1x for over a year and respectfully disagree with many of the conclusions drawn in this video. But I also approach 1x from a different perspective: road cycling. I don't do mountain biking, cyclo-cross, gravel or cross-country. Let's address the 5 "problems" in the order presented in the video:
    1 - Chainline and back-pedaling
    In my opinion, the biggest error demonstrated in this video was a bad chainline in some of the author's bikes, then blaming the 1x system for it. The true problem was this: the author's chainring was not centered properly to his cassette, period. You cannot expect any drivetrain (1x, 2x, 3x) to perform properly with a faulty chainline. Singling out a 1x was wrong. Any bike mechanic worth his/her salt will quickly tell you how many bikes have bad chainlines -- even from respected manufacturers. One of the worst I've ever seen was on a Specialized Ruby Elite with a 3x10 Shimano 105 drivetrain. The only non-Shimano component in the drivetrain was an FSA crank and it located the center chainring almost 7 mm outside of the centerline of the cassette. You can imagine how badly off-center the large chainring was -- it was atrocious!
    When I converted my road bike to 1x, I was very careful to create a good chainline. I've never had any back-pedaling problem whatsoever. My SRAM Red crank has a Stages Cycling power meter on its crank arm. So I back-pedal frequently to activate it and pair it to my cycling computer before each ride begins. I back-pedal for several minutes each time I lubricate my chain -- which is often since I cycle 5000-6000 miles per year (8045-9656 km). Never has it dropped off the biggest gear! Nor has it ever sounded bad!
    2 - Power loss
    As above, this was primarily a chainline problem. If the chainring was properly centered to the cassette, the chain would be quieter because there would be less friction when cross-chaining. And let's remember that cross-chaining should be less of a problem for a 1x drivetrain than any other setup (2x or 3x) because the 1x has only one chainring and, if it is properly centered to the centerline of the cassette, the offset of the chain at either cross-chaining extreme will be less. This is simple geometry.
    If the chainline is properly centered, the biggest reason, in my experience, why some 1x drivetrains are a little noisier compared to a 2x is because of the alternating fat/narrow teeth on the 1x chainring. The wide teeth rub the plates of the chain more than the all-narrow teeth of 2x chainrings. This is more noticeable when cross-chaining.
    But the issue of power loss presented in this video focused on only one part of a complicated issue. There are both benefits and deficits for these kinds of 1x chainrings. First, let's remember that they were designed with cyclo-cross in mind. The designers were thinking how to make it harder to drop a chain while improving efficiency of a dirty drivetrain. SRAM's X-Sync 1x chainrings claim to: (1) engage the chain pins earlier so more links are simultaneously pushed by the teeth, and (2) clear mud from the chain. If the first claim is true, it should add to the efficiency. Will it offset the increased resistance from the fat teeth? I don't know. And neither does the author of this video. I think it will take careful testing on a bike with a properly centered chainline and a power meter before any conclusions can be drawn. As for the second claimed benefit of clearing mud, that was addressed by the video in its 5th "problem" discussed below.
    3 - Lack of gears
    There's no argument here on the main issue. When you convert from a 2x or 3x to a 1x, you will have to give up some gear ratios. You might give up your largest ratios and have less top-end speed. Or you might give up your smallest radios and have less cadence on the steepest climbs. Or you may give up a little of both. This is the best reason why a 1x system is not for everyone. Each individual cyclist must assess his/her needs and choose a drivetrain that best satisfies them.
    However, I disagree here with what I perceive as the "smaller" issue of cadence. Don't get me wrong: cadence is extremely important and I've lived with a power meter long enough to know all too well why a high cadence is often better than a low cadence when a high power output must be sustained. What I disagree about is how many gears we actually need. In my opinion, we've got too many! Perhaps my opinion is colored by my history. I started with 2x6 road drivetrains in the mid 80's and it seemed like plenty to me. I rode for years over all kinds of terrain with 52,42t chainrings up front and a 14-30t 6-speed cassette at the back. The only thing I wanted was more top-end. I almost never used the small chainring.
    A 1x10 or 1x11 provides plenty of gear steps to maintain an 80-90 rpm cadence on most any road. Riders who claim to need more and finer steps between gear ratios in order to fine-tune their cadence seem crazy to me. I honestly believe that the only reason we have so many gears on our bikes today is because of marketing by bike manufacturers who each try to out-do the other so you will buy their bike instead of a competitor's bike. You may not agree with me on this point -- and that's fine. But I, for one, only use an 11-speed cassette because I'm forced to because virtually all of the rear derailleurs that I'm interested in, use them. For example, if you need multiple shift points (handlebars and aerobars) you'll have to use an electronic drivetrain and all of their rear derailleurs are 11-speed.
    4 - Higher maintenance
    Yet again, this comes back to the chainline problems demonstrated in the video. Until you fix the chainline problem -- that is, until you properly center the chainring to the cassette -- you cannot blame the 1x for higher maintenance. After many thousands of miles, I've seen zero indication of increased wear on my chain, cassette, rear derailleur or chainring.
    5 - More frequent chain-drop from chainring
    The video claimed that dried mud on the wide teeth of a 1x chainring caused the chain to come off the 1x chainring more frequently than a 2x setup. I'll take the author's word for this problem because I have no experience with it. I'm not exposing my road bike to the kinds of harsh conditions that the author exposes his bikes to and I'm using a much larger 50t chainring. Yet it seems that the faulty chainline in the author's bikes may play a mitigating factor here. If the incidence of dropped chains correlates to his 1x chainrings not being properly centered to his cassettes, then the faulty chainline may bear a large part of the blame -- not the wide teeth of the 1x chainring.
    My road bike has a composite carbon frame so dropping a chain can be extra serious. I've seen lots and lots of composite bikes with severe damage to the bottom bracket shell when a chain dropped past the inner chainring on a 2x setup and began to cut through the carbon before the rider stopped trying to pedal. When I used a 2x drivetrain with my frame, I always made sure to protect the frame with a chain catcher. With my 1x setup, there has been no need for one. So, if you are not exposing your bike to mud and other hazards, a proper 1x setup should have far less risk of dropping a chain.
    Plus, these new 1x chainrings are still a work in progress. As I understand it, SRAM made design changes to the teeth of their X-Sync chainrings last year. I'm using one of the original ones on my bike and I haven't had a chance to see one of the new ones yet and therefore don't know what differences were made. Perhaps SRAM has improved theirs so this isn't an issue any longer. I don't know. But there is still on-going work in this area and updated products are coming to market.
    Summary
    ------------------------------------
    Because the 1x chainring of some of the bikes in this video appeared to be offset from the centerline of the cassette, the chainline (or driveline) was faulty. For this reason alone, many of the conclusions drawn by the author were premature, if not incorrect. How should you configure the chainline for a 1x drivetrain? Intuition would lead most of us bike mechanics to locate the chainring dead-center to the centerline of the cassette. In this case, the offset of cross-chaining would be identical whether you chose the smallest gear or the largest gear. However, SRAM (with which I'm most familiar), advises favoring the outside a little. So I set my chainring a little over 1 mm to the outside of the driveline. This means the cross-chaining offset is a little less when I'm shifted into my smallest (fastest) gear vs my largest (slowest) gear. This seems to work fine for me. And, as I mentioned above, I've has zero problem with using my largest gear -- even when back-pedaling.

    I would say that there is a lot of logic in your words. 1x could fit in some circumstances but is definitely not what they say it is.
    On my trail and on my road bike I use 2x10 and from my point of view and experience I think 2x10 is the most balanced gear type - not so expensive, very reliable (chain drop, chain and cassette wearing, etc.) , enough gear ratios for speed and for climbs. Another very useful thing of the front derailleur is that it can put your chain back on the front chain ring if it drops off, just by pushing your left shifter.
    For sure all these different standards have one goal - the profit of the industry. Some new ideas and technologies are of great benefit for the users, but most of the time is just marketing.

    The industry is laughing at us. As a civil Engineer I can tell you that chains are designed to transfer direct stresses from one point to another, in other words to apply power from a given prime source to a receptor, they wear badly when lateral stresses are applied and yet that is exactly what the "1" by systems do. The industry knows that, of course, but that ensures that it makes more money out of the customer. Wear on the reduced elements increases proportionately. As a consequence, the cassette will require more frequent replacement than a system incorporating a triple or double chainring. So will the chainring. The triple and double chainring systems are designed for a purpose and that purpose has not been diminished in imperative by Bike Industry "fashions". Be clear......ultimately the single chainring is an expensive experiment. This chap here is quite right in his analysis and if riders do not like his perspective...for their own reasons...that simply does not obfuscate the basic laws of engineering.

      I agree. It is all marketing to maintain or increase profits. Innovate or die is the phrase that comes to mind. In this case innovation does not always equal better. That being said I do find that my new mountain bikes 1 x 12 Sram Eagle system has the big advantage to me in that I no longer have chain slap against the rear chain on a fast bouncy decent, chain suck, failure of the chain to shift to the lowest chainring when starting a climb, or drop the chain off the small chainring when making a big downshift from the large chainring at the start of a steep climb(happens quite a bit even with the front derailleur properly adjusted). Also I have never experienced a chain drop-down from backpedaling. In addition it is great to have the dropper post lever mounted where the front chainring lever used to be. But I do miss the lower gearing on really steep climbs in terms of cadence that a 3x system provides. However, I will stick with the 3x system on my road bikes as I don’t see any positives to switching to the 1x system, only negatives in terms of cadence, friction, and wear and tear.

      I agree with Bob. 2x and 3x is nice as it allows you to help avoid crosschaining, and has more of a selection for gear ranges. But 1x is also nice because you only have one shifter to worry about, and can use a southpaw lever where the front shifter was for the dropper seatpost. That is one of the main reasons why I'm switching to 1x on my mountain bike.

You can really see the mountain biking industry in the last 10 years has so many different standards/sizes for everything from drive trains to axles to wheels to suspension. It is great to have choices but sometimes it is a bit much.

    It is funny that every new trend (I won't call them innovations) is sold as a replacement, not as a supplement, to all that is currently sold. The manufacturers have to legitimize your purchase of parts you don't probably need by convincing you that you are falling out of fashion and losing time if you don't buy the new stuff. Are 1x setups better? For some riders and situations they absolutely are. Are 2x and even 3x setups better for some riders? Absolutely they are. We need to stop trying to buy ourselves into being faster or more fit and try to do it through riding what we have.

      1x setups are actually still pretty infant, at least on the side of the large manufacturers. The smaller ones satisfied an existing demand with narrow/wide chainrings, conversion kits and what not. They didn't push anything, they just saw a demand for something that was not too readily available. And so, just now are Shimano and Sram catching up with this trend. There's a huge demand for 1x setups and nobody is pushing it. Manufacturers are struggling to keep up.
      27,5 and 29 wheels have overthrown 26" wheels. Many see it as a conspiracy of manufacturers. But consider the fact that all three sizes have been available for several years. It's just that sales of one of the sizes were not justifying continued investments. That's why most brands don't have high-end 26" bikes. They just don't sell.
      if you think of it, 26" wasn't established because it was the best possible solution, but because at the time it was the most common on mountain bikes. So all the research and development was made around a 26" wheel. It was a trend at the time and it took a long time to make a viable alternative. When the alternative was available, people spoke with their wallets.

      Limited; Romanticizing a new thing is pushing for sales. dropping production of something that has slowed in sales is creating market. notice how the two are linked. Even I would not stock 26" bikes right now because there is too much hype for the bigger wheels. I'm sure that Nino would beat me senseless on a three-by, 26r. A wise man once said " Skip the hype, ride the bike..."

      There is a large population of MTB riders who ride purely for fun and not competitively. Many of us also ride highly technical trails that require mix of climbing and downhill, not to mention highly varied version of both. 1x and "lighter weight this" "less chain drop that" are all fine and dandy, but I'd rather get a wider range so I can climb more efficiently, and if the chain drops going DH (which is usually where it happens), it's not going to prevent me from going DH. 1x setups actually benefit you in way fewer situations than what manufacturers are trying to promote, and it's more of a fad fueled by ignorance and marketing than anything else.

  • @LukaVelic
    @LukaVelic 7 лет назад +17

    Everyone should try 2x11 and 1x11 before buying a new bike, I find it more a personal preference than anything else. I have the cheapest SRAM NX 1x11 system and it works great for me on my hardtail. No backpedalling problems and downhill speed is a non-issue since when you're going 40kph+ you're not going to pedal anyway since it's too bumpy and pedal strikes can occur.
    I agree that the components wear faster and it could be an issue on some more high-end groupsets which tend to wear faster anyway and are more expensive to replace all the time.
    Anyway, try both and see which you prefer.

    for riding technical trails I often found that trying to change the front chain ring gears fast resulted in chain drops or chain jams. I'm testing the 1x drive train now and so far it seems better for me. Also, I never run out of low end or top end speed on those kind of trails with steep uphills and technical downhills.

      Of course there will. We all used to ride 1x way back in the day ffs, but then people invented the 2x and 3x because it was an improvement! More gears gave you more options, smaller "jumps" between gears etc. That didn't suddenly just stop being the case. It's quite clearly a marketing push and nothing else.

I feel like left behind when new bikes are at the park / lights, in their pretty group sets, but having the range makes all the difference day after day. AND I never need to change setup for the next event. lLve the channel. Go Poland, great decade for pro racing!

  • @thesuperkat943
    @thesuperkat943 7 лет назад +83

    1. Nobody needs to backpedal 8 rotations super quickly in any situation
    2. Riders DO have a choice. 2017 uci downhill in vallnord saw many 29" bike riders switch back to older bikes on 27.5. Why? Because it made them faster, and that's what matters.
    3. They don't have to use what the company specs on the bike. One of the pro downhill bikes (forgot what event, but I can find it if it's super important) had a custom rear shock built by the team mechanic, again because it made them faster.
    4. While the louder cassette does show there is power loss, I would have to argue that the loss of weight from removing 2 rings, 4-8 bolts, and extra crank material will make up for the power loss.
    5. The "lack of gears" argument is total bs. With 2x and 3x drivetrains, many of the gear ratios overlap, so a bike with 20 or 30 combinations only truly has 12-15. On a more personal side, I run state XC races with a 11-34 10sp with a 38t up front. I don't even use my lower 3 gears, so don't tell me that I need A) more weight and B) another point of failure.
    5. The lack of cadence argument doesn't matter, because this isn't road biking. Mountain biking is designed to make riders deal with rapid changes that are dealt with by either rapid pedaling or slow, powerful strokes. And again, you don't get that many more unique gears.
    6. A 500% range in gears for now 500$ with gx eagle will provide for plenty of range, with great affordability. This means that for 500$, someone could outfit their bike for enduro type events.
    7. If you are running out of gear, get a bigger chainring.
    8. Matinence with a 1x is cheaper and easier than a 2x or 3x. While it *might* wear out faster, you are not replacing front cogs or a front derailleur. And if the chain is your main concern, just find a kmc x10, X11, or x12 sl dlc chain for ~60$ (with some shopping), and never change a chain again. I've had dropping problems with shimano chains due to stretch as early as 6 months in, but have been running the same kmc chain for close to 3 years now.
    9. The chain would pull on the rear derailleur anyways, and carbon flexes without fatiguing, so it wouldn't matter anyways.
    10. If you really don't like 1x systems, why do all of the bikes shown run 1x?
    11. Dropping a chain in 1x is easier to fix than dropping on a 2-3x. A 2-3x also runs the risk of twisting a chain or pinching the chain if it catches. 1x drivetrains are also less likely to drop because of clutch mechanisms holding tension and front cogs, such as wolftooth, having longer than standard teeth to lock in gears in addition to more effectively designed teeth. I will add in that I have dropped chains on the 1x system, but these drops were due to chain stretch, a disengaged clutch, a worn out narrow wide with shorter teeth, and bad line choice, but only took 5s to fix. Also, chain guides exist.
    12. The new sram narrow wide cogs are now made with longer teeth and more efficient mud shedding geometry than present on 2x and 3x systems.
    Going back to the price argument, with a 1x, you won't have to buy a front shifter, front derailleur, or front cogs.
    13. You don't get enough speed because you put a 30t on it like a tard.
    14. The fact that you chose the bike with the smallest gear range, chain hop when reversing, and the one that's more road oriented than mountain oriented is pretty ironic and counter intuitive from my perspective. Just saying.

      To be honest I held back from 1x for a while. I converted a 2x10 to 1x just to see. Moving the front chainring more inboard so it is more in-between the original 2 chainrings. In extremes the angle is fine and I get zero problems if I were to back pedal. Will I go back to 2x? No
      I agree whole heartedly with you.

  • @matthewkramer8613
    @matthewkramer8613 5 лет назад +11

    Have been eyeing the 1x11 bikes and admiring the industry effort to put such a system together as a wide spread standard. Previously, I road a 1x1 mtn bike and really appreciated the simplicity. Obviously this is very different than 1x11 but not having a front derailleur lends to just more focus on the peddling. I have also spend a great deal of time on 2x10, 3x10, and 2x11. For mountain and road bikes, my vote is the 2x. With 2x the range for high and low can be better grouped with decent chain lines, and more often than not the front chain ring will stay in one ring most often. But this does depend on the cassette group you have and where you ride. Where I live, it is modestly hilly. Therefore my lower range gets the most use. So again a clean chain line is important. I believe most people will not bother with refining these details of their bike and just go with the stock setup. And this is maybe why 1x11 -etc. had gained popularity, intending to try to keep the drive train simple for the average rider.
    Having an extreme chain line with questionable low gears seems less appealing.
    Additionally, when I look at the back wheel with all that metal and think shouldn't the rear wheel be lighter.. I mean this is where all the power is being pushed to and should not be bogged down with all these monster sprockets.. The weight comparison has got to be more for the same gear ratios. Maybe someone should do a video on that.. Personally, I like to keep the bike light. With 2x all those cassette sprockets can be smaller, with only the one additional chain ring on the crank. ( maybe with the extra shifter and front derailleur it all evens out, but would be fun to reveal)
    One thing that is appealing for 1x is the amount of torque and leverage when using a smaller chain ring with the bigger cassette rings.. For off-road this ideal especially with the lower range.
    Maybe being a little more old school, I am more biased.. I am sure that at some point my 2x drive trains will be toasted, and if 1x is still a thing I will be joining the club but only as a last resort.

  • @raheemgahelable
    @raheemgahelable 5 лет назад

    Hey, sick biker; 3 things you may have forgotten to consider.. ; 1. The brand of the chainring compared to the brand of the chain. 2. The brand of the biggest rear cog compared to the brand of the chain again. 3. The proper alignment of the chainring using spacers if needed! I've been using 1x10 for 4 years now , and sometimes the chain drops if I pedal backwards on the biggest gear in the rear ( 30tx 42t) , I personally think that the only way to know if your chain is lined up right, is that when you see a 100% straight line chain when you shift to the 5th gear if you're 1x10. This is just my personal experience.

  • @TheTurboGfx
    @TheTurboGfx 7 лет назад +12

    Tested 1x11 for about 4 months now (27.5 Enduro bike with 32t to 11-42) and I have to say it works great for me. Lowest gear is more than enough for the climbs I do. I agree with you that you could spin out on in the highest gear but this only happens to me on the road sometimes. On the trail I have none such issues because if I go faster then this gear would allow me I wouldn't want to pedal or wouldn't be able to cause of the terrain. My bike came with 3x10 and I had serious chain drop problems in the front nearly every second ride. Now they are gone with a little top guide. Also I found myself like never using the 40t chainring especially off road. So long speech short: 1x11 works really well for me on Enduro, freeride but I see that in other categories where your cadence and pedaling skills are more important 2x10 or 2x11 would be better. Cheers.

  • @MrSkurnz
    @MrSkurnz 4 года назад +4

    Thank you. Fantastic film and I do agree with you. I have always felt multiple chain rings on the front is better, like you say for the bigger range of gears. Another problem with x1 is big steps between gear ratios, but that will happen as you have less gears!!
    Most riders go 1x as it's what the manufacturers fit them and also it's fashionable. I think another reason riders like 1x is that a huge amount of then don't know how to setup and adjust front derailleurs.

  • @richarde1355
    @richarde1355 4 года назад

    Bravo! I am so glad you posted this video. I can't tell you how many people call their 1x conversion an "upgrade"; I don't view it as an upgrade, I just view it as a conversion. It's just different, not necessarily better or worse. There are arguments can be made for 1x, 2x, and even 3x systems. Unless a person is competing, a 2x or 3x system offers many more cranking options than does a 1x. It's just math. And, as you pointed out, cadence can get out of whack when there are such big gaps in between gears. And, then there is the cross-chaining issue. Finally, I can't believe how many people will say they have issues with sprocket changes on a 2x or 3x; I find many of those folks who say that have never even had a bike set up that way! They have been fed certain information and are just repeating what they've been told, not sharing their experiences.
    Unfortunately, many new or modern bike riders have been taught only 1x systems are good, slacker fork angle is better, super wide bars for mountain bikes is better, you can't stop your bike if you don't have 4 piston brakes, etc. Makes one wonder how those competitive bikers in, say, 2010, did as well as they did? In my opinion, but perhaps folks should focus more on their technique and conditioning instead of their equipment. I believe it's because it's a lot easier to change the equipment than it is to get fit and more skilled...
    Thanks for all of your awesome videos.

    Thanks for these opinions - I liked the 3x7 setup on my entry-level MTB 10 years ago. The gear ratios & range were already optimised, and the outer plastic chain guard at the front would prevent the rider's leg contacting the greasy chain, and also helped stopped the chain falling off to the outside (better it jammed in the gap between the large chainring and the plastic guard, perhaps). Good practice as well for the mind, to operate both derailleurs all the time!

    My pros and cons:
    + 1x lets me focus on the trail and not on shifting - great help on unknown technical trails when you don't know what's around the corner.
    + Dropper lever doesn't fight for space with the shifter.
    + Lighter.
    + No dropped chains when narrow wide chainring was new-ish, no chain device.
    + No backpedalling issues.
    + 32x(11-36) on 27.5 is just fine for the trails I ride (no roads, no smooth downhills).
    + More clearance (smaller chainring).
    + Can use Zee derailleur - super compact, light, cheap & works great.
    - Chainline not perfect (need to get some spacers for chainring next time). But it's okay, no backpedalling issues.
    - Dropped chain a few times now (chainring worn out).
    - Chainring wears out quicker.
    Verdict: I'm loving my 1x10 converted from 1x20 :-)

Brand new bike with new XO1, I was really looking forward to trying this new drivetrain. Several times I was looking for higher gears, and on quick descent to ascent sections, I couldn't change gear quick enough; a problem I never used to have with my 2x drivetrain. Could be a matter of getting used to the new drivetrain, time will tell. Well done for sharing this vid with us all.

    Lack of gears is the killer. When I bought a Mach4, I could not afford the 2x build kit ($1200 more than the base model). So I'm living with a 1x11. The lowest gear is barely adequate, and the highest gear SUCKS, I can't goose it on those fast downhills.

      Ed, I found I, too, lost range when I went with a 1x10. Not only that, but I’d have to run through all 10 gears to get from high to low, instead of just dropping into my smaller chainring. I went back to 2x10, because wanted the extended range.

Gives me about 3 more gears to drop and I get the speed I want. Love the bike now. I found before changing to the oval I was only using 5 gears out of 12 now am using 8 or 9 out of 12 now.

I'm pretty sure in a couple of years when most of us are annoyed by this 1× hype, the bike industry will come with something totally new and revolutinary: Brand new hot 3×13 drivetrain. For my part, luckily I got one of the rare 3×11 equipped Bikes (Centurion Numinis 2000.27 2016) with Shimano Deore-XT (M8000 series). Year, this thing really rocks as well on the steepest uphills as on fast trails or downhills. It has simply none of the disadvantages you mentionned. XT 3×11 is still available with a FC-M8000-3 crankset.

  • @z1522
    @z1522 6 лет назад

    Thank God a person actually clarifying the shortcomings of the latest fad. Especially for MTB, the change from 3x10 say, to 1x11, is a sacrifice of yes, 19 lost gear options! Less a few near redundant ones, the change results in very large steps between gears, opposite of what roadies have learned regarding cadence and spinning optimally at every speed; either high or low gears are always sacrificed as well, because the single front ring dictates what the maximum is going to be, and no one is making a 72 tooth cog -yet. For the majority of riders, a 2x system is the minimum for optimizing gear range, intermediate gearing steps, and avoiding the extreme issues introduced with the 1x fad foisted initially by SRAM.

  • @spooky8172
    @spooky8172 7 лет назад +5

    Thanks for sharing your findings. Maybe some of the points also need to be distiguished as to going to a 1x standard range (say up to 36t) or 1x wide range (anything over 36t ie 40 - 50t), as the wide range setup creates it's own additional problems over sticking with standard cassettes, chainline/chainangle, lower RG pulley etc
    May I add a few of my findings?
    a) - / + Chainline
    The chainline in the low gears on bikes that were not specifically made to be compatible with wide range 1x drivetrains is horrible and will cause problems like noise due to chain angle and dropping the chain when backpedalling. HOWEVER, there are manufacturers that have addressed this issue and have adjusted their current frame designs to suit 1x drivetrains. I believe Cannondale have done this with their asymetric rear end which is why your CD is working quite well. LITEVILLE have also developed their free to all manufacturers EVO6 rear dropout standard (hopefully more will pick it up) which is based on BOOST but adjusts the chainline to work better with 1x drivetrains.
    b) - dirt and grit on the front ring
    Dirt and grit on a wide narrow ring causes horrible grinding noises and acceplerated chain and ring wear due to the tighter fit. This causes rings to wear quicker, and in winter and makes riding less enjoyable.
    c) + cleaning
    Cleaning the front ring from grit and dirt is a reason why I love 1x drivetrain. it is so simple to engage the RD (SRAM), pop the chain off and clean the front ring, this was always a pain with 2x and 3x drivetrains.
    d) - / + range
    Of course with a 1x drivetrian you lose range. For some it is a problem for some it is not, everyone needs to decide for themselves. I personally am looking forward to trying 1x12 with larger range. The issue I see though, and again this needs to be decided individually, is how far the derailleur pulley drops down. It amost touches the rim!
    e) -/+ Clutch
    Many people don't realise the clutch mechanism wears and at some point the clutch actually no longer serves it's purpose without an adjustment of the friction it provides. It happened to me. X01 drivetrain worked a treat until 6 months down the track: race run after having no problems in training. Chain dropped off. I later learned my clutch had worn and needed adjusting to work again. A 1x drivetrain without a working clutch will drop chains.
    a) - bearing wear cassette
    The inner bearings of freewheelbody are usually made to withstand the torque from the cassette with a standard cassette. Many freewheelbodies are not yet adapted to the higher torque that wide range cassettes provide and you'll just distroy the internals in a quick time. Some manufacturers have upgrade kits available so that you don't distroy the internals. Just something to bear in mind many people would overlook when upgrading to 1x.

      With the 1x12 with range of 10 to 50 teeth there is still a range problem becouse the gap between the gears is very big, so you still have to compromise for these.
      What you say as the last point is plain wrong I think, since your max speed is much lower with a 1x groupset, the maximum power put on the cassette is also lower (no the power you produce, but the mechanical power brought over by the chain), so actually the new cassettes are better for the freehub (if used as 1x setup as intended), but even if not so, the Tork a amateur can produce is still nothing in comparison with a pro, so the bike will probably handle it well.
      To get a good chain line when upgrading you should also look at the offset in the front, to get it aligned nicely, or as nice as you can get for the reasons mentioned in this video.

    Thank you so much for your review. I am a 61 year old 'Touring' bike rider and was being tempted by all the hype etc to swap to a 1 x system, but having gone from a 9 speed 3x by taking off the 42T front chainring and just using 32 /22 at the front and a 11-42 cassette my knees have found great happiness.
    I should also add that recently I made it up Bealach Na Ba fully loaded with this gear set up, although it did take some time!!.
    Thanks again

    Hi. I have walked trough the following path with good results:
    1st - Own a training bike 2x10 that is also apply for special XC ocasions with a M6000 group.
    2nd - Keep a customized racing bike 1x10 with XTR Rear Derailleur +XTR Shifter and a Deore Crank Set with 38T Narrow-Wide Chainring that gives me enough speed with a Sunrace+SuperCog 11x48 Cassete
    Lesson Learned: ALL purpose bike is almost an Impossible Mission if you want to balance performance, components lifetime and cost saving! (my experience...)

    Always knew sponsored riders - being paid - aren’t going to be upfront and if they want to get sponsored, will parrot what the manufacturer tells them. That’s the way it works.
    Obviously, 75% of MTBers will go with the marketing flow. Those who ride more often, push harder, will soon realize the costly downfalls in the newer technology. I never had issues with front derailleur and enjoyed the ability to drop quickly to a lower gear. I never replaced a front derailleur. I can see that cross chainline as being a major issue for wear and replacement if you ride in mud, sand and peddle hard. Not to mention the tension arm and pulley swinging even lower than ever for those big gears.
    As a consumer, we’ll have to adapt as I don’t see any new bikes with 26” wheels and front derailleurs.

    Great video! I just started riding this summer and got a mid-level XC bike with 3x and as a newbie I of course wondered why all of these 1x was thought of as the best. Mainly actually because of some of your problems - mainly 3 and 4 (and now two other things to think of). I have been using all gears in the 3x (although seldom the smallest one), and since I'm still quite physically unfit (fat) I'll keep it that way until I really have to upgrade or buy a new bike in which case I think a 2x will be the best for me. Also - as a new subscriber, thanks for many other great videos!

    I'm so happy to hear you bring this up. I recently bought a new full suspension bike and made sure it had 2x10 system. One thing I find which is never discussed is street riding, which I do a lot of, I use my lower ring about 30% of the time. This is significant. Basically the math does not work for me. 2x10 is better than 1x12. The wright savings aren't big enough(that huge 12 ring has to weigh a lot). The loss of the front gear mech means nothing to me(I like symmetry). And I love my cadence!

    @jackmitchell5187 3 года назад

    This is one of those videos that I'm so glad somebody came forward to point out the pros and cons. My one by 11 drivetrain on my Roscoe 8 came stock with quite a small sprocket. I picked up an oval 34 tooth sprocket in gold looks great performs quite well. So that's what I did to attempt* to remedy some of the same complaints I have about one by drivetrains. If someone was looking to put a larger one on I wouldn't go much larger than that, he clearances were pretty close. The oval does have a different riding characteristic and helps improve hill climbs but I literally have all the issues you pointed out in this video! LOL the one that drives me the most crazy is not having crisp shifts all the way up and down through all 11 gears. I brought it into the shop and they helped me adjust it pretty well last year but now it's going back out of adjustment. I started throwing at it the other day got a little bit better but man I wish it was more improved. Feeling like the overall design should should have stayed 1 by 10. You made some excellent points very well outlined, Thanks so much for sharing!!

  • @gmatochautube
    @gmatochautube 7 лет назад +91

    #1 - gear skip on backpedal - good demonstration, but in 3 years of riding 1x10, I've never had it happen.
    #2 - power loss - Sure there's a bit of power loss in the chain line, but there is power loss in a 2x or 3x setup too, just to a smaller degree. So it's not like you're NOT losing power with a 2x or 3x, so it's a matter of degree...probably fractions to single digits of watts. How much power is the extra weight of a 2x setup costing you on the same climb?
    #3 - Lack of gears. Absolutely fewer gears. But for most people on most trails most of the time, they don't use the full range anyway. So do you want a bike that's optimized for 95% of your riding? Or add weight, cost, and complexity just to pick up that extra 5%? But your point about racing is spot on - if you're a competitive race, you might use the extra gears.
    #4 - Maintenance - any additional maintenance induced be 1x would, IMO, be more than offset by eliminating maintenance on the front derailleur and its associated components.
    #5 - chain drop - again, it just doesn't happen for most people (more than on a 2x or 3x) with a proper setup.
    I agree with Martin - great video with good demonstrations and kudos for selecting a range of bikes. But your "big problems" are not "real world problems" and don't outweigh the "real world advantages" of 1x for most people.

      @substance1 7 лет назад +3

      And the cost savings is not so great when you look at the price to replace an 11 speed cassette, and it will need to be changed more often because of the dreadful chain-line, ditto on the derailleur.

    • @mohammadfahmy7976
      @mohammadfahmy7976 7 лет назад +1

      One of the main advantages (at least for me) is the reduced weight by removing my front derailleur, and a chainring. This ,of course, is a preference. You can offset the added weight of a 2X or 3X system by the wider gear ratio. However, that means more maintenance with the 2X or 3X system (derailleur, cables, housing, and more chainrings to take care of and replace when worn). 1X doesn't give you the same amount of gear ratios but to me I don't need a wide range of gear ratios. However, in 2X and 3X systems you ratios overlapping so the difference isn't as big as one imagines. I would go for a 2X system if I'm racing to get some good speed from a larger chainring, which I wouldn't use when commuting around the city. If you think of converting your bike to a 1X system make sure you set it up properly. Key factor (for me) was the chain alignment, with 11 and 12 speed cassettes because they cause the chain to be in an awkward position (i.e. not being straight in the drivetrain) making it susceptible to dropping.
      In summary: reduced weight, and less parts to maintain/fix/replace :)

    I converted my Shimano 105 road bike to a 1 by 8 drivetrain flat bar bike. I replaced the 50/34 crank with a 44 teeth crank , wich is almost in the middle of 50/34. Luckiliy I did not have to adjust the chain line. In order to not loose the chance to maintain the optimal cadence (80-90-100 rpm) I have chosen the proper cassette for it, and everything works just fine so far. I can't hear any bad noise from the rear also. I think if people dont forget the chain maintenance then such a drivetrain should work just as smooth as a 2 by 10 or 11. And if You stick with a 3/32 chain (5 to 8 speed systems) the chain or cassette wear is not an issue since they're much much cheaper than the 9-11 chains and cassettes.

    Very well balanced arguments! Well worth the watch-time. Even though I personally still prefer 1-by and hadn't had that much issues. Probably because i prefere more technical, and thus slower decends - combined with rather pushing/carrying the bike on steeper/more technical ascends.

    Great explain, driving now 1 x 10 drivetrain , singlespeed 32 - 11-42 , at the beginning my chain was falling off , fixed it by install a chain guide and a better chainring. Now my experience is that a 32 chainring with a 11-42 casette the difference between the gears is to high, example i can climb now at gear 4, I'm driving a 1 x 10 drivetrain, so i will go to 36t at front. Also i have problems with switch the gears but the main problem is my derailleur from SLX is designed for a maximum casette 11-36, so im considering to go back to a casette 11-36. Well , still love mountainbiking, nothing will stop me :)

    I ride a 3x8 mountain bike and I have no need for a 1x drivetrain. The 3x8 system gives me plenty of gear for steep technical uphills and downhills on the road. It's a lot of fun to see a huge hill and jump down a whole bunch of gears with the front derailleur. Sorta like engaging the lo-range on a 4wd vehicle. For me, training myself to operate the bicycle better in terms of shifting a complicated drivetrain is more fun than eeking out a few more watts or few seconds on a course.
    1x drivetrains make sense for someone who races and has a lot more on their mind. Not having a front shifter frees up space on the handlebars for other buttons like dropper posts or active suspension control.
    But for me, a front derailleur is not that complicated, makes fun clunking noises, makes bike operation more rewarding, and as a non-racer, who cares about a few extra grams.

    I use a 1X system on an old 1996 road bike. Only seven gears with 38T front and 12-32T rear and it works quite well for me as a slow casual rider. Chain cross over is not very extreme with only 7 gears and I don't get chain drop with a front narrow wide chain-ring and not much chain slack on the highest gear. The derailleur is an old 1996 Shimano meant for a 2X setup but works fine.

  • @1972hermanoben
    @1972hermanoben 4 месяца назад

    A front derailleur is useful when cadence matters or when touring with heavy loads and lots of hills or varying terrain: for 90% of the rest of us, a 1x presents a minimal drop in efficiency in exchange for less hassle and a small reduction in weight - just remember to check your chain regularly. However, you might find your drivetrain showing wear much more quickly. In the absence of ‘missing’ gears, you may end up putting down more power in order to compensate, putting more strain on the system. Chains last longer on a well-set-up 2x / 3x system.

  • @avoycendeether8869
    @avoycendeether8869 7 лет назад +4

    Cross-chaining losses on your biggest cog are somewhat (largely) ameliorated by the fact that bigger gears are more efficienct than smaller gear combos. But there are still losses. For example, 53-28 vs 39-21...similar gear ratio, bigger gears in for the former but it's cross-chained. In that case you're talking about ~7.75 watts of friction vs ~7 watts of friction. So it's definitely a measurable difference but probably not meaningful to most. Definitely the frictional loss would measure in the milliwatts in most cross-chain scenarios, at least vs the realistic alternative which isn't perfectly aligned either.

    • @avoycendeether8869
      @avoycendeether8869 7 лет назад +2

      I should add that the real cross-chain concern in 1x setups is not on the bigger cog because, again, bigger gears are more efficient & that ameliorates the cross-chain inefficiency to some extent. BUT if you pick a chain line that cross-chains on your smallest cog you have some real inefficiency when you're in the 11. (again, smaller gear, less efficient) For example, 53-15 vs 39-11...pretty much same gear ratio but the 53-15 combo generates something like 7 watts of frictional loss while the 39-11 combo generates closer to 10 watts. So if you pick a chainline to optimize your largest cog cross-chain...you'll get dropped in the flats. You're much better off picking a chainline to optimize your 11 cog or closer to the 11 clog at least.

      How do you figure that 3 watts is going to get you dropped in the flats? Riding on the hoods at 20-25 MPH means you're expending 200-400 watts. So that's about .75 to 1.5 percent-not enough to matter in any practical sense, unless you're a pro racing for several hours or days.

    There are more than 4 problems with 1x anything:
    1. chain does not like to travel by side/diagonaly, and when it goes it wears teeths by side, wears itself by uneven load on pins of chain, front ring gear is more loaded on left side in touching point of chain for low gears and more loaded on right side on higher gears ( so more powerloss, noise and wear of components)
    2. to ensure high range of gear ratios, rear derailleur is more loaded by chain tension on lower gears so here is more powerloss, noise and wear( pulley of derailleur are more loaded and in some cases upper pulley can touch teeths of first gear)( my 1995. dura ace metal pulley lasts 60000 km)
    3. gear rings will live longer if for same conditions are used ring gears with more teehts( for ex: 22/18 has same gear ratio as 32/26 so if is not to much chain diagonal is better to use 32/26 than 22/18, for 2/3x systems
    4. if chain falls from front gear ring , it has to be set by hands( no front derailleur)
    5. there is only 1 gear ring for same gear ratios/speed so some gear rings will be worn faster because are more in use ( for 3x 8/9/.. rings can be combinated for same ratio)
    Summary : manufacturers offer worse option that will last shorter and they will earn more money ( on naive people)

    I think there is entirely too much hype surrounding the latest greatest bicycle stuff. Truth of the matter is unless you are physically capable of placing in the top 10 in just about any race consistently, then you are just spending money to spend money. Chris Froome for example would still kick your ass on a 200 dollar 3x7 Tourney groupset bike from Walmart if he didn't explode the bottom bracket out of it. People are always so concerned about the latest greatest lightest stuff...you want lighter? Put down the cake and pedal more. You want faster? Train harder. The thing that makes the most difference on a bicycle is the legs pushing on the pedals.If I get dropped, it has nothing to do with what bike I am on, it all has to do with ME and that is free to upgrade...with work and effort. Some of the fastest people I know are riding steel bikes from the 70's-90's they pulled out of scrap piles and restored.

      I also don't know if this helps anyone else, but my auto insurance agent knows how much I ride (I work with her husband) so she was able to get an auto insurance discount for me.

    It's great to hear this as we know that crossing chain rings is a bad thing, so why we think because it sounds good to have a "simpler" way to shift that somehow magically without something obviously addressed visibly to counteract the major crossing that would have to be occuring with even a seven speed heck we all hear the noise that occurs when it is 4 gears changed at best without the front shifting down or up/in or out. In my opinion a 3 ring cassette, or freewheel is the most one can get away with without clear hints being audible which means obvious damage is occurring for all to witness as it is happening. You can ignore it, but you better be prepared for two things which is having money on hand to change parts which should last a lot longer instead now you’ll be replacing it often in comparison as well as not being as efficient on your best day as a 2-3x chainring depending on how many gears you have. It sucks to hear, but it should be a duh moment as this is nothing new to anyone of us even slightly familiar with how a shifter works and why they were invented in the first place.

    Im a 1x guy.
    I rode 3×10 shimano slx for 2 years now.
    Last week I replaced my my old 3× m612 crankset with a 30 tooth raceface affect crank.
    And after one week I can already tell, its a hell of a difference.
    1. Its 550g lighter
    2. I never had a chaindrop and I have zero problems with backpedaling.
    3. The narrowwide chainring does not even need a chainguide
    4. Its quiet now. The old shimano front derallieur produced a hell of a noise which was ultra annoying.
    5. It looks so clean.
    6. I have now less gearratio (11-36) but it works for me (iam more the freerider , iam not racing)

  • @drewc6842
    @drewc6842 4 года назад +1

    The first two problems could be fixed by running a bigger offset chain ring (running a non boost chain ring on a boost bike). But yeah 1X is really an enduro thing that has been trickled down. XC probably should have stayed 2x but the industry tends to follow gravity trends (thru axle, boost, dropper post). Ix is good for gravity less likely to drop a chain down onto the smaller front chain ring as there isn't one and you can run a wide narrow which won't drop a chain as easily (and gravity doesn't need the choice or efficiency that XC does). For me 1X is way better and the 2x derailleur used to let the chain fall off anyway, its not a substitute for a chain guide in my experience.
    Though I do think 11 speed and 12 speed are stupid, we end up with very skinny chains and super fiddly derailleur indexing (a small bump of the rear derailleur will wreck the shifting) as the gears get closer together. The chains, cassettes and chain rings wear faster and are weaker. All I want is the range of eagle on a 1x9 or 1x10, way more reliable, stronger and way easier to setup. I don't need the choice of gears, us gravity riders have strong legs :D

  • @szaboattila5081
    @szaboattila5081 5 лет назад +1

    Gear drop while padelling backwards is not because of "chain line". Used to have a 3x10 with a 11-38. I know it is not okay, but even at the worst chainline (biggest in the front and at the end too), it never ever dropped, even though it is a lot worse compared to a 1by. 1by was perfect with a 11-38 casette. Then I put on a 11-42 casette, and it dropped from the 42-40 cogs. Chain drop is caused by the fact that your rear derailleur has a capacity for the biggest cog. If you put on a casette with bigger cogs than the capacity of your rear d., itll drop. You can buy hanger extenders online (forget LBSs) and it will give the rear derailleur extra 4 teeth capacity.

    I have about 20 years old MTB. Really old school one. What I love about front derailleur is that if I ride on flat, leveled surface and there is short uphill part all I do is drop one step on front chainring, pedal up that short hill and when back on leveled road just go back on bigger one in front and thats is. So it takes only one shift down and then one shift up. If I would want do that on rear casette, I'd have to shift about three steps up and then three steps down again for the same effect. I am really a casual cyclist and there is still original chain and all drivetrain on that bike after 20 years.

    It makes sense simply because a chain will need to move in like 10-12 different angles so it would put more wear. I have a 1x10 Marin Rock Spring 2 hard tail mountain bike and I have not experienced any shifting issues (Deore) at all as it is so buttery smooth. Never chain dropped and never crunchy grinds at all. Before I purchased the bike, I thought that it would be little bit slow but I was surprised how fast I could go. I hit 30mph on it with its thick knobby tires on the road. I don't see myself needing to go any faster than that or near that especially on mountain bike trails. I climb very well too. I do like the user simplicity of a 1x drivetrain and also the reduced weight from not having another crank, another derailleur and another shifter and cables. Everybody tries to find ways to reduce weight. Do I think the 2x can go faster and has more various useful speeds? Sure.... Price is also a big factor too and I was able to get my bike for an awesome sale price and the 1x likely helped lower the price vs a more expensive 2x with additional parts.

    This guy is completely right, this is why i`d much rather use my old 7x3 vintage mtb or my 6x2 1983 road bike. On the road bike, cross-chaining is basically non-existent, the original drivetrain lasts forever. Meanwhile, the new 9/10x3 drivetrains need replacing every 4 years, which isn`t exactly cheap. The industry is going backwards while telling people what an improvement the new stuff is. Most costumers are fools anyway.

  • @dylanwillick7919
    @dylanwillick7919 7 лет назад +1

    I'm a bit bias because I really like my xx1 set up, but some of these problems are really nit-picking in my opinion.
    First Issue- it's rare that you spin backwards for more than half a stroke which is almost never enough to throw the chain off
    Second- The wattage loss is really so minimal, none of us are pushing 800 watts for more than a couple seconds so even if you lose 5 watts it's not statistically relevant, would equate to fractions of a section each ride
    Third- Sram has better gear range than shimano and if you can push 800 watts you can push a 34t chainring uphill. In terms of cadence I've always found its dictated by the trail more than your gears
    Fourth- maintenance is an issue but at least each time you replace a cassette all the gears are roughly equally worn whereas there are overlap gear combinations on 2/3by that mean some cogs see little use
    Cost is definitely high, but the way I look at it is when it comes time to replace components, it's gonna cost about the same as a similar spec 2by and I think it's a better option. Also, I've dropped a chain once in the last year and a half on my 1by or there's the ever effective 30 gram chain guide if you're paranoid

  • @josh33172
    @josh33172 6 лет назад +12

    The two chain drops has more to do with the tension of the rear derailleur and the clutch adjustment.
    Also keep in mind, SRAM and Shimano didn't design their 1X systems with Cannondale's chainring in mind.
    Also what adjustment do you have in the chainline with a BB30 bottom bracket. So yeah, the C'dale may have been optimized for a 2X system, but that is due to the specific bike design...and once again, SRAM/Shimano didn't design their 1X systems with that C'dale in mind. They have to design their systems to fit a plethora of bike types and brands. If companies aren't designing their bike around these drivetrain systems, that's on them.
    As for the gearing of the trail bike. In all reality, they are not really designed to hit those super fast AND SMOOTH descents that you're doing 40+km/h......as weird as that sounds. They're designed to descent more technical terrain FASTER than your C'dale hardtail. There is a threshold in which speed is no longer useful on those bikes because you're either going to hit a jump that is outside the bikes capacity or too rough for the suspension to actually keep up and allow you to remain in control. Your test is outside the scope for what the bike was designed for. You get that Canyon in it's native environment....twisty, rocky, technical, loose, rooty, drops, step-ups, step-downs and you'll see yourself using every bit of that suspension, every bit of the gearing, and it will blow that weight-weenie FSi away. They're two different bikes with two different focuses in mind, and different gearing to match.

  • @Jordan-bq9sp
    @Jordan-bq9sp 7 лет назад

    The big thing is that manufacturers are starting to make bikes specifically for 1x drive-trains. They include shorter chain-stays, which helps with cross-chaining and other issues mentioned. additionally a lot of 1x systems built from random parts won't match up. If you get a bike that is built for 1x, with a 1x drive-train with components that are actually meant for each other, issues are minimal. Look at the engineering in XX1 Eagle. That's a system that is meant to work and does so near seamlessly.

My 1x has a 38t chainring, which is a good ratio for speed and cadence on the flats. It's also provides me work great speed on the decent as well.

  • @MrPunkassfuck
    @MrPunkassfuck 7 лет назад +43

    That backpedaling and chain dropping would be HUGE for me offroad. I did that ALL the time. The only relevant argument for 1-by seems to be that it's easier to shift. Really? Who struggles with shifting? Show me one person. I would counter it by having to gearshift LESS if you have 2 or 3 front chainrings. Since you can drop the chain down by one on the front chainring instead of shifting with rear derailleur 5 times. 1 press vs 5, which is easier?
    Companies have to make stuff incompatible and poor quality. Otherwise no one would buy anything. If bikes lasted for 20 years, how long b4 a company has sold all the bikes possible? And theres 20+ companies making bikes, right? Would it take a year? 2 years? To make a billion or so bikes. They make stuff incompatible so you would be inclined to upgrade. And make it look like it's different. Just different enough. I don't trust anyone who starts a sentence with "We have all this new technology and therefor...". Metal is metal, carbon is carbon. The bike has looked the same pretty much since 1885. Quick release was invented in 1927!
    Ooh, aerodynamics of bike was increased by 2% compared to last generation. And the bike is at most 20% of the drag factor. so 2% of 20% = ....0.4%? Wow, much impressed, such innovation!

      OR
      hold and press gearshifter til you find the right gear, going up or down approx. 5 gears in the rear? What is that? Pumping shiftlever twice? And counting how many shifts that was?
      I would choose option number one.

    • @lucasgauci
      @lucasgauci 7 лет назад +10

      Obviously you don't go over rough terrain. With 1X system, it allows you to run a narrow wide, and a chain guide which great stops chain drops. With 2X and 3X you can't do this, and the front mech is so inefficient at shifting as you have to back of the power a little to change.

      Your logic is ridiculous. Penicillin was discovered in 1928 and do you think we still use the same exact drug today? No! The basis is the same but over the years it has been improved. The Ford model T was made in 1908. Do we still drive it or use the same technology today? No! The basis is the same but over the years it had been improved. more RESEARCH and DEVELOPMENT has concluded with today's cars being very safe and efficient. Therefore saying that the bike is the same is very ignorant of you. And if you start talking about a 2% increase compared to last generation, over 10 years that equals 20%. And that is a big difference. In the Olympics do you see the 100 metre time get broken by a whole second? No, every 10 years of so it is broken only by a little bit. Do you understand how ridiculous you sound.

    • @MrPunkassfuck

      Well, someones pissed off...Good.
      You are comparing machines to humans with the Olympics stuff.
      Are you still driving a Ford Model T? Are those for sell? Because quick releases are.
      Do you understand how bacteria work? They mutate every 20 minutes or so. Of course the same penicillin wont work for long, same with antibiotics. So the medical field HAS TO create a better version, one that bacteria can't circumvent. A bike doesn't rust and fall to bits if theres no innovation.
      2% of 20% is still 0.4%. So in your argument that would total 4% over 10 years. Bike manufacturers don't necessarily release new gens every year. Not with aero improvements.
      Why do we still sit in the same position? Why aren't racing bikes more like recumbents? Or a bike where you sit like superman? Wouldn't that halve the aerodrag? Since we would be twice as low.
