I tested a 1x setup by riding in my 50t chainring all the time and I could climb all the major hills in Montreal with an 11-30 cassette. I will actually go full 1x with a 11-32 cassette next season.
Would you be able to use an 10 or 11 speed 1x chainring with the 12 speed chain? Since the internal width of the 12speed chain is the same as 8,9,10,11
You can save a whole lot more weight by going 1x in the rear (single speed) perfect for flat lands and big guys like you. I use SS for my Z2 flat rides.
@blueshun That's exactly why my 12.8kg fat tire road bike is such a steamroller on flats! People underestimate the rig until they see what I can do in a makeshift TT position (forearms resting on flats, head tucked). It just plows!
I don't mind 1x, I have it on my gravel/allround flatbar bike that rarely sees proper hills, but I never understood argument of better chainline. I guess if you compare it to cross-chaining on 2x, but if you shift in the front when needed for sure chainline is better than in 1x extreme gears.
I think the idea is that you spend most of your time in about 3 gears next to each other and you can optimise the 1x to have perfect chainline for those gears. When you have 2by you have perfect chainline in really fast and really slow gears. I don't know if it works out that way in practice tho.

What you do you think of the this being a thing in the future 1x13 drivetrain, and getting rid of front derailer all together? where to buy this chain ring: alugear.com/chainrings-1x/290-15690-round-1-speed-for-12sp-110-bcd-4b-shimano-asymmetric-roadgravel.html#/40-size-52t/15-color-green
Hopefully we would never see the day where manufacturers only releasing 1x compatible only drivetrains just like disc brake nowadays. It doesn't mean that if Wout Van Aert use 1x that suddenly that's what you gonna use with your bike. I'm all about proper gearing even though let's say you're just gonna ride flats today having extra gearing makes more sense than faffing around changing your 1x crank set when you wanna ride on the hills.
1x is not for everyone and every situation. For certain situations, 1x is definitely the way to go. For most of the riders/situation, 2x is the way to go. I have 1x as well as 2x bike and use 1x mainly for my gravel bike.
I could seem them easily push this in the future making a 13 speed group road oriented and having a 1x chainring, having a 10-50 in the rear or something like that and a 48 in the front
@@GCPerformance18 I did some more research and what I found suggested that 1x is about 3 watts less efficient on avg, because you get more bend in the chain at the high and low ends of the cassette. With the 2x setup you can be in the optimal front ring to decrease bend.
In a one-by the chain is under extreme stress at the top most and bottom most sprocket gears. The front derailleur helps with that. The entire drivetrain suffers worse than a 2-by.
I am using 50-34 with 12-25 or 11-23 cassette on the flat. I wanted 1X, but my bike was 6.8kg with double. I think the 11-speed 12-25 with a good sized 1x chainring is the best for flat roads.
@@thedownunderverse it was a perfect fit as long as you are mindful when sliding it over the crank it won’t get scratched if you want to be extra careful I recommend I few pieces of painters tape on the crank before installing the chainring then just peel it of when it’s installed
My thought is 1x even in the hills, but like 13-36 on the rear and like 48 on the front. Very rarely am I 10, 11 or 12 and if so I’m downhill and a lot of time I’m coasting. How often am I drilling it going downhill when I don’t race my bike?
For me wide range gear on a road bike is a huge no, recently swapped to a 42T inner (52T outer) with close ratio 11speed : 11-25 cassette, this is the best upgrade i have made for efficiency, yes, it is not as light but far more useable than a 1x, perfect cadence at all speeds. I use 1x on a Cannodale Slate gravel bike and it feels like I'm constantly in the wrong gear.
1-"Just get better at cycling" I live in a hilly place. Not too much, but we frequently ride at our smaller chainring in a group. Let's make the calculation and find out how good I have to be. 4% gradient and want to go without grinding. If I run with 50x14 at 90 RPM, I ride at 26kph. (75kg rider) I have to run at almost 380 watts.!!! You can always run with your smaller chainring. In this case, you have to cross your chain. If you live in a flat area and even a beginner can average 30 km/h, then use the 1x system. But if you live in a place with some hills and if you have to climb more than 3% or 4% in your daily rides 1x system does not make sense. (Talking for mortals among us) I'd like to see how you get uphill comfortably with your 1x setup. Then we can talk about "being a better cyclist" 2- You only get a better chainline for 1 gear... In 2x Setup you get 2 straight chain lines.
Just to add to your second point, the outer cogs actually get worse with 1x. Most people would never cross chain that far up/down the block on a 2x, but you have to with 1x
so the 1x set sits in between the big and small chainring, thats where it lies, so when people are in big and big already, how it would it be worse then? people do cross chain people do run those big gears in the big chainring, but if the 1x setup is closer to the frame, in what world is it worse?
@@GCPerformance18 If you get a straight line at 6. gear on your 1x System, you get at both 4. and 9. strait lines on 2x System. You have to cross your chain more with your 1x System if you want to use your biggest and smallest rings. @facingup1624 is right. No one who understands the gearing system will go 52 front and 30 rear in the 2x system anyway. They will switch to 36 front and 24 rear...
a shop that tells me to get better at cycling when i say I think something might not be right for me, is a shop i wont spend money in. And yeah, Florida might be one big pancake, the rest of the world has hills. Also, the best advice i've ever got for tracking down the source of creaks is to get yourself a stethoscope
How do your easiest gears work? I have this same setup with Alugear 54T and 105 di2 RD + 11-34 cassette. Top 3 gears grind and are incredibly loud. Wondering if it will get better as the ring wears a bit
I have no issues, depends sometimes on chain compatibility, as you can see i am running a mountain chain on there for looks, but sometimes certain chains until they wear down they are noisy at first
14:29 I always wondered if that's normal. The chain is flapping enough to hit the chain stay. I had this happened to many of my 1x drivetrain bikes. I used frame protector to temporarily solve the issue. I guess it's a common 1by problem.
Hey great vid! I tried this setup. Same Chain Ring, same Groupset. How do you deal with cross chain? It has weird noise on low gears and high gears extreme
I wonder if i can do this to my2x mechanical grx 810 on my cervelo since i have never used the small chainring?can i fit a 50t chainring with the grx 2x derailer its running a 48/31 now
Not from my experience. I've used my current 1x setup for around 6 months and not a single chain drop. I live in the UK where the roads are known to be full of potholes too.
I have always enjoyed your videos. And when I come to visit my son in Ft Lauderdale, I would like to stop in your shop. But this is a crazy setup for me. I live close to boulder of, South Carolina, and North Carolina. Often to bike the Blue Ridge Parkway. Where I live in the Upstate of South Carolina, my rides are often 50 miles with 3000 feet of Climbing. I would have no problem with a 1x; I never use my small chain ring. A 53 -34 is no problem, but once I get into the 3 to 8-mile at 13 to 15 percent climbs of the mountain in North Carolina, I love the 36 - 34. Not unusual to climb 8000 feet in 70 miles. 1x setup is for the birds.
Just bought one of these because my fd broke and I don’t really need it around here in Chicago. Anyway I was wondering if I would need a new chain that a few links longer or if my chain that I have right now will be fine. I’m going from a 50-34 to just a 50 tooth.
Hi Grant, I have a question for you regarding the frequency of chain drop issues with Shimano compared to Sram and Campagnolo. I'm curious if Sram's marketing tactics have influenced your perception, as my understanding is that Sram front derailleurs are often associated with chain drop problems. It seems like rather than addressing the issue directly, they market their 1x setups as an innovative solution. Additionally, I wonder if many professional cyclists are compelled to use 1x setups due to sponsorship obligations. There are several videos highlighting instances where pros on sponsored teams don't use Muc-Off products due to issues.
I don't think Sram has that much sway over the strongest team of the tdf. I honestly think it was the better setup for them. Less weight and more aero. It's not like they need extra range.
What is the offset on the Alugear chainring? Did you need to add spacers to the chainring bolts or bottom bracket to get the right chain line? I’m getting ready to convert to 1x with a SRAM dzero 110 bcd spider and a Garbaruk 1x aero chainring (48 tooth with 0mm offset). Comparing a SRAM 1x direct mount chainring 40 tooth to Garbaruk, the SRAM is offset 3mm closer to the frame. Worried I may have some chainline battles ahead. Therefore, I’m curious if the Alugear has offset.
I do not know off the top of my head but mine is shimano so I do not need spacers for mine but for sram dub I would run the same bb spacer on the crank that comes with the same chainring
What chain and lube are are you using? I have the ALUGEAR 52t and a 11/30 cassette, but are getting a lot of noise from the chainring. Only 3 position on the cassette is okay, the rest are so loud (noise) 🙄
Yep I just noticed this too! Garbaruk’s are excellent .. and alugear is veeeeery similar (right down to the font and etching on the ring) so I’m guessing these will be great. Prolly come out of the same factory
I just installed the chainring for 12 speed but need to sent it back cause the chain cannot align straight when the gear in the small or the biggest position.
really? that is weird, I have not had this issues, and i ran it on 2 different bikes. what group you run? and also is the bb installed correct for spacing?
I live in actual mountains. My weekend ride often includes Mt Mitchell. I’m not going to 1x on my road bike any time soon. But when I lived in the flat? It would be very tempting now.
I've done a bunch of rides with my SRAM 48/35x10-36 setup where I haven't left the big ring. And I don't live in Florida (usually I get more than 100m of elevation per 10km around here. Sorry, too lazy to convert to freedom units). Granted, those were fast group rides and I wouldnt want to be stuck with a 48x36 easiest gear when I want to do a Z2 ride. But for a N+1 scenario, I probably would build a 1x road bike like this just because it looks good and is a nice flex.
Alugear products bare a striking resemblance and the same chain compatibility as Garbaruk chainrings (which are excellent). Another interesting observation - both are made in Poland
@@GCPerformance18 What’s the chainline like on this setup? Does the Alugear chainring on the 105 crank line up dead straight with the middle cog on the cassette? It’s a super important aspect of 1x setups….
Any reason you picked the alugear over the garbaruk? Also are you still happy with the alugear? I also live in South Florida and looking into going 1x on my ultegra 12 speed crank. Thanks
II have an 11 Speed Ultegra set up. Are there any issues with just removing my front deraileur and leave the Crankset alone for now. I am not worried about weight. I just hate any chain rub noise. I never use the small chainring. Thanks in advance... Great Channel
If you’re running a 2x Ultegra 12 speed groupset on the Elves, can you run a 54/40 chainring setup with that bike? And what’s the largest that you could run on that same frame if you’re running a 1x?
I don’t see why a 12 speed 54/40 crankset from Dura Ace can’t work with 12 speed Ultegra. They’re basically the same 12 speed group. Look for large 1x TT chainrings. FSA has full carbon 64T chainring used in last years 2022 Tour de France time trials.
yes u can run a 54/41 that is a new standard and it replaced the 53/39 so there is no issue, you can run a 54 1x on there they make the bigger chainring options with a little more offset
My last ride was 87.5 km and 2205 m of elevation. All within a 12 km radius from home. Including some very steep sections peaking over 20%. So, yeah, for me a 1x is not the ideal solution. I'd need a MTB cassette and I don't think that would be the best for road riding. But, on flatter regions of the world... Yeah, why not?
I could never find a good cadence with the limited range one bys provide. It's not worth losing that range and chain efficiency because you're to lazy to shift the front rings. Ofc on a singular type of terrain it works but I like to pedal up hills as well a down them
In FL 1x makes the best sense. It’s a clean look on that bike! Question would it be better to space the big ring more “in board” to get a better chain line?
This is a huge downgrade. Good if you like to run on a flat track. Terrible if you go up hills in the city And the chain line is not straighter. It is straighter for beginners who forget to shift their front. Triple is the one that actually gives straighter lines assuming the rider is experienced at not cross chaining.
Ive seen that brand of chainring online and the little ends to finish off the spider arms. Seems to be a popular thing now having a single front ring. I've purchased the Specialites TA with their 'spider arm' ends to finish it off, but I've still kept the 50t/34t, for my new 2023 Bianchi Oltre Comp. Love that frame and bike, it looks very cool indeed Sir
What would I need to buy if I have the older sram red etap to go to a 1x11? Im good with all the gearing since I’m in Florida also and never go into the small ring.
I have the 1x prev gen allez sprint and building a new gen with a 1x as well. I really like the fact that I don't have to shift from small to big ring at the summit of those rolling hills in Tenn. I did struggle a bit climbing long steady 12%+ grade when I took that thing to Taiwan. I have looked at the Jumbo Vismo's setup as well.. most of them ran a 48 to 54t with 34 or 36 rear on their S5. Not sure about their R5 climbing version
I'm from where Pogacar and Roglic are and here we need setup like Roglic had on the last stage of Giro. But with that setup its hard to ride in a group. 13s Ekar would be much better but still gears are to far apart for climbing and riding in group. We have too many hills 😅
I'm running 50-34 on the front with 11-34 on the back. That 34-34 gets used up the 15% and greater climbs around here. I suppose a 50 front and 11-50 on the back would work, but would it really?
How do you feel about chainlink when in the largest cog? I have the same chainring on BB30 (130 bcd) in a 46 11/34. Very noisy in the 34. I'm using KMC chain ? Have had wolf tooth in the past, and they seemed to a more quiet.
I like the ultra wide 2x from Wickwërks. Said it also work with SRAM chains so going to test it at my new TT build. 53/34 with 10-28, if it works. But otherwise I run 11s on my roadbike. It's so with that range. Wherever you go you have the gearing you need.
The argument surrounding pros being 'strong enough' to use a 1x is completely superflouous. It doesn't matter how strong they are. They want to be as efficient as possible. If 1X is more efficient, for them, it's more efficient for everyone. If it isn't, it's not. Yes, they could muscle it up a 10% climb better than we could, but they're up against other pros on 2x, so if that's the better option, they're wasting energy.
Love my 1x drivetrain!! I have plenty gears for going uphill, i have a 40t chainring with a 11-52 cassete which is more then enough. If anything ill go with a bigger chainring if i need more speed.
I'm in decent shape and 1x on a road bike is not enough gear for me here. I run a 38 11-51 on my gravel bike because we have a bunch of 20% climbs and its ok for gravel but im spun out in groups and descents on a road bike. Id like it though because i hate front derailleurs.
I need a drive train for my touring bike for my transamerica ride...I will be loaded with 50lbs of gear on my steel frame bike. I'm not a strong cyclist so need to sit and spin when climbing.
1x is not effective if you live in a hilly place. I run a 48/31 with the 11-34 and anything about 4-5% grade and I need the 31 to climb. With that being said I would need like a 42 front chainring or smaller if I want to be able to still climb above 5% grade. Here comes the big issue with that, when I go downhill I’m already running out of gearing with the 48 up front so a 42 going downhill would be useless! 1x are for very fit cyclists or cyclist who don’t climb.
would have like to see the front mech hanger to be removed for aero and weight gains (but l run an alugear on my TT bike and 1x on many bikes like offroad and commuter. not on the training road/race bikes since it's medium hilly over here and need the range) so yeah ... would like shimano to come up up a proper 1x road groupset or at least a cool crank and not just the GRX
It doesn't give you a better chain line though, unless you're in the middle of the block. As for weight saving, well you're going to need a bigger cassette which will be much heavier unless you spend big money and DA only go upto a 34T cassette, and you're gonna be grinding up hills with a 50-52 chain ring and if you use a 46 or 48 chainring you'll be spinning out on decents. I guess it could be beneficial if you live somewhere flat.
The climb to my house hits 18%. The shortcut has a long 24% section. I can do a 50 mile ride to a ski resort that tops out at 10 or 11%. No matter my local ride, the last 1/3 mile is always the toughest. No 1x for me (except my XC bike with a 34 ring and 10-50 cassette.) Also, doesn’t a 1x have MORE cross chaining? Big-big or small-small is slightly straighter than middle-big or middle-small. And why worry about a few grams on the flats? Yeah, for Florida, I can see going to 1x, but the day you take the bike on a trip for an epic ride, it could be painful. Maybe it depends on if you’re a grinder or a spinner. Me? I’m a 65yo spinner. And I couldn’t compete with the pros when young. 2x for me on the road all day long.
But to account for what? The big cog, little cog, 3rd from the right? The big ring will always nudge things towards the little sprocket and the little ring will always nudge it towards the big sprocket. Isn’t that what we want? When people say that “a 1x gives an optimum chain alignment”, I think they’re just repeating a bad line. It’s optimized for what, one gear? It can’t possibly be better aligned for them all - especially at the extremes of the cassette.
I am using 1X, but 40T chainring, it's way enough for me. Do you really need 52T chainring? 52T with 10T in 90 cadence will be 61kph. I don't know man, not many people can ride this fast
It's more efficient because (1) the chain is straighter and (2) you are using the larger cogs. A lot of people think it's for max speed and focus on that too much. I'm running 54/40 in FL. Much better than the 52/36 I had.
I don’t think I’d do it without a rear derailleur without a clutch. Also, please enjoy riding up 12% with 50t/33t small gear. I’m not Jonas Vingegaard lol.
I don't buy the single chainring crossing less. The outer chainring is closer to the 11/10 sprocket, and per Shimano specifications I never go past the 8th sprocket either (21 on a 11-30 cassette). For super flat terrains is OK cause you'll rarely get to the extremes of the cassette.
Florida man tells cyclists to get better at climbing, installs 1x on a Shimano drivetrain because SRAM can't make a good front derailleur.
Hahahhaha

@@patrickrenschler3 watts is totally lost in the noise. Its nothing unless you’re WvA - are you WvA?

What crank are u running on there? GC used FC-R7100 but alugear site says its compatible with 12sp Dura Ace and Ultegra.. it doesnt mention 12sp 105
@@thedownunderverse I’m using mine on 12 speed 105 di2
@@catchthedream1142 amazing! thanks for responding… was it a good solid fit without being too tight and scratching up the crank?
@@thedownunderverse it was a perfect fit as long as you are mindful when sliding it over the crank it won’t get scratched if you want to be extra careful I recommend I few pieces of painters tape on the crank before installing the chainring then just peel it of when it’s installed
I am running 1x for many years now on all of my bikes (MTB, road & gravel) and I love it. Not going back.
My thought is 1x even in the hills, but like 13-36 on the rear and like 48 on the front. Very rarely am I 10, 11 or 12 and if so I’m downhill and a lot of time I’m coasting. How often am I drilling it going downhill when I don’t race my bike?
not sure how 1x is more efficient in terms of chain line.
For me wide range gear on a road bike is a huge no, recently swapped to a 42T inner (52T outer) with close ratio 11speed : 11-25 cassette, this is the best upgrade i have made for efficiency, yes, it is not as light but far more useable than a 1x, perfect cadence at all speeds. I use 1x on a Cannodale Slate gravel bike and it feels like I'm constantly in the wrong gear.
Perfect cadence on hills below 7% maybe!
1-"Just get better at cycling" I live in a hilly place. Not too much, but we frequently ride at our smaller chainring in a group.
Let's make the calculation and find out how good I have to be.
4% gradient and want to go without grinding. If I run with 50x14 at 90 RPM, I ride at 26kph. (75kg rider) I have to run at almost 380 watts.!!!
You can always run with your smaller chainring. In this case, you have to cross your chain.
If you live in a flat area and even a beginner can average 30 km/h, then use the 1x system. But if you live in a place with some hills and if you have to climb more than 3% or 4% in your daily rides 1x system does not make sense. (Talking for mortals among us)
I'd like to see how you get uphill comfortably with your 1x setup. Then we can talk about "being a better cyclist"
2- You only get a better chainline for 1 gear... In 2x Setup you get 2 straight chain lines.
Just to add to your second point, the outer cogs actually get worse with 1x. Most people would never cross chain that far up/down the block on a 2x, but you have to with 1x
so the 1x set sits in between the big and small chainring, thats where it lies, so when people are in big and big already, how it would it be worse then? people do cross chain people do run those big gears in the big chainring, but if the 1x setup is closer to the frame, in what world is it worse?
@@GCPerformance18 If you get a straight line at 6. gear on your 1x System, you get at both 4. and 9. strait lines on 2x System. You have to cross your chain more with your 1x System if you want to use your biggest and smallest rings. @facingup1624 is right.
No one who understands the gearing system will go 52 front and 30 rear in the 2x system anyway. They will switch to 36 front and 24 rear...
As with most things in cycling, the manufacturers will not give the consumer a choice in the matter.
What is the weight difference for the change to the larger cassette?
a shop that tells me to get better at cycling when i say I think something might not be right for me, is a shop i wont spend money in. And yeah, Florida might be one big pancake, the rest of the world has hills. Also, the best advice i've ever got for tracking down the source of creaks is to get yourself a stethoscope
Is there any limit to how small gear you can go? For example if you go 48t and a 10-44. Anyone tried? ;)
How do your easiest gears work? I have this same setup with Alugear 54T and 105 di2 RD + 11-34 cassette. Top 3 gears grind and are incredibly loud. Wondering if it will get better as the ring wears a bit
I have no issues, depends sometimes on chain compatibility, as you can see i am running a mountain chain on there for looks, but sometimes certain chains until they wear down they are noisy at first
14:29 I always wondered if that's normal. The chain is flapping enough to hit the chain stay. I had this happened to many of my 1x drivetrain bikes. I used frame protector to temporarily solve the issue. I guess it's a common 1by problem.
Hey great vid! I tried this setup. Same Chain Ring, same Groupset. How do you deal with cross chain? It has weird noise on low gears and high gears extreme
If you wax the chain it helps a lot but it’s just for a little for the beginning wear of the chain on the chainring
@@GCPerformance18 Do you mean that as time goes by the weird sound will just go away due to normal wear?
I wonder if i can do this to my2x mechanical grx 810 on my cervelo since i have never used the small chainring?can i fit a 50t chainring with the grx 2x derailer its running a 48/31 now
The rear derailleur needs a clutch, or any bump could drop the chain from the single ring
Not from my experience. I've used my current 1x setup for around 6 months and not a single chain drop. I live in the UK where the roads are known to be full of potholes too.
@@lemonshire1agree, a good quality RD and good quality ring are enough for all but the narliest off road
I have always enjoyed your videos. And when I come to visit my son in Ft Lauderdale, I would like to stop in your shop. But this is a crazy setup for me. I live close to boulder of, South Carolina, and North Carolina. Often to bike the Blue Ridge Parkway. Where I live in the Upstate of South Carolina, my rides are often 50 miles with 3000 feet of Climbing. I would have no problem with a 1x; I never use my small chain ring. A 53 -34 is no problem, but once I get into the 3 to 8-mile at 13 to 15 percent climbs of the mountain in North Carolina, I love the 36 - 34. Not unusual to climb 8000 feet in 70 miles. 1x setup is for the birds.
Just bought one of these because my fd broke and I don’t really need it around here in Chicago. Anyway I was wondering if I would need a new chain that a few links longer or if my chain that I have right now will be fine. I’m going from a 50-34 to just a 50 tooth.
nice!!!! no problem at all it is the same size so you wont worry
@@GCPerformance18 alright perfect thank you
You think it will fit iwth 4iiii double side powermeter in the cranks?
yes of course
Hi Grant, I have a question for you regarding the frequency of chain drop issues with Shimano compared to Sram and Campagnolo. I'm curious if Sram's marketing tactics have influenced your perception, as my understanding is that Sram front derailleurs are often associated with chain drop problems. It seems like rather than addressing the issue directly, they market their 1x setups as an innovative solution. Additionally, I wonder if many professional cyclists are compelled to use 1x setups due to sponsorship obligations. There are several videos highlighting instances where pros on sponsored teams don't use Muc-Off products due to issues.
I don't think Sram has that much sway over the strongest team of the tdf. I honestly think it was the better setup for them. Less weight and more aero. It's not like they need extra range.
What is the offset on the Alugear chainring? Did you need to add spacers to the chainring bolts or bottom bracket to get the right chain line?
I’m getting ready to convert to 1x with a SRAM dzero 110 bcd spider and a Garbaruk 1x aero chainring (48 tooth with 0mm offset). Comparing a SRAM 1x direct mount chainring 40 tooth to Garbaruk, the SRAM is offset 3mm closer to the frame. Worried I may have some chainline battles ahead. Therefore, I’m curious if the Alugear has offset.
I do not know off the top of my head but mine is shimano so I do not need spacers for mine but for sram dub I would run the same bb spacer on the crank that comes with the same chainring
Nice setup! Is that Alugear compatible with the Magene PES 505 Power Meter?
Yes I am currently riding it right now
@@GCPerformance18 Sweet! Thanks for the feedback!
Can you do a video on Rotor Aldu Carbon aero crankset ? Significantly lighter that dura-ace, with very tight manufacturing tolerances
What chain and lube are are you using?
I have the ALUGEAR 52t and a 11/30 cassette, but are getting a lot of noise from the chainring. Only 3 position on the cassette is okay, the rest are so loud (noise) 🙄
I am running sram eagle chain and silca super secret lube
Can you show us what the alugear chainring and the Magene power meter cranks look like together?
yes I have them on video with the prestacycle cassette
Yeah, I like it. And that chainring is cool. And when you're using the small range road cassette, it saves even more weight than a big 11-44
Alugear are made in Poland, the same as Garbaruk, or Absoluteblack ;)
Yep I just noticed this too! Garbaruk’s are excellent .. and alugear is veeeeery similar (right down to the font and etching on the ring) so I’m guessing these will be great. Prolly come out of the same factory
@@thedownunderverse They are not from one factory, everything is made at home, in different cities, but both are made in Poland ;).
I just installed the chainring for 12 speed but need to sent it back cause the chain cannot align straight when the gear in the small or the biggest position.
really? that is weird, I have not had this issues, and i ran it on 2 different bikes. what group you run? and also is the bb installed correct for spacing?
I live in actual mountains. My weekend ride often includes Mt Mitchell. I’m not going to 1x on my road bike any time soon.
But when I lived in the flat? It would be very tempting now.
I've done a bunch of rides with my SRAM 48/35x10-36 setup where I haven't left the big ring. And I don't live in Florida (usually I get more than 100m of elevation per 10km around here. Sorry, too lazy to convert to freedom units).
Granted, those were fast group rides and I wouldnt want to be stuck with a 48x36 easiest gear when I want to do a Z2 ride. But for a N+1 scenario, I probably would build a 1x road bike like this just because it looks good and is a nice flex.
With sram the best part is you can build a 1x roadbike for 30€ in 10 min. Just screw off the front mech and put on a 1x chainring.
Alugear products bare a striking resemblance and the same chain compatibility as Garbaruk chainrings (which are excellent). Another interesting observation - both are made in Poland
Thanks for the info!
@@GCPerformance18 What’s the chainline like on this setup? Does the Alugear chainring on the 105 crank line up dead straight with the middle cog on the cassette? It’s a super important aspect of 1x setups….
Any reason you picked the alugear over the garbaruk? Also are you still happy with the alugear? I also live in South Florida and looking into going 1x on my ultegra 12 speed crank. Thanks
II have an 11 Speed Ultegra set up. Are there any issues with just removing my front deraileur and leave the Crankset alone for now. I am not worried about weight. I just hate any chain rub noise. I never use the small chainring. Thanks in advance... Great Channel
What up GC....Do you have to resize or get a new chain when you go 1x?
no you dont need to, if its the same size chainring
If you’re running a 2x Ultegra 12 speed groupset on the Elves, can you run a 54/40 chainring setup with that bike? And what’s the largest that you could run on that same frame if you’re running a 1x?
I don’t see why a 12 speed 54/40 crankset from Dura Ace can’t work with 12 speed Ultegra. They’re basically the same 12 speed group.
Look for large 1x TT chainrings. FSA has full carbon 64T chainring used in last years 2022 Tour de France time trials.
yes u can run a 54/41 that is a new standard and it replaced the 53/39 so there is no issue, you can run a 54 1x on there they make the bigger chainring options with a little more offset
Does a 54 alugear chainring fits the new 105 crank?
yes it does
I also forgot to say. On the way down those climbs, I need the 53 -11 in order to keep in contact. We have no flat rides.
how do i get in contact with you at your bike shop for any orders....thanks....scott
You can email me at gcperformanceyt@gmail.com or call the store bicycle generation Deerfield beach Florida
My last ride was 87.5 km and 2205 m of elevation. All within a 12 km radius from home. Including some very steep sections peaking over 20%. So, yeah, for me a 1x is not the ideal solution. I'd need a MTB cassette and I don't think that would be the best for road riding. But, on flatter regions of the world... Yeah, why not?
Bro I subbed cuz of the video editor jokes bahaha 😂😂
Great Video ! I use a 46 Wolf Tooth chainring GRX 1X & 9-46 helix rear cassette on my Sirrus X 5.0 , no dropped chains
200feet on a 30 mile ride, I would go 1x but I live in the hills and most tours start with 600 feet after 8 miles :D
Honestly im thinking of ditching the fd too… 1x also looks so much better
I could never find a good cadence with the limited range one bys provide. It's not worth losing that range and chain efficiency because you're to lazy to shift the front rings. Ofc on a singular type of terrain it works but I like to pedal up hills as well a down them
In FL 1x makes the best sense. It’s a clean look on that bike!
Question would it be better to space the big ring more “in board” to get a better chain line?
They have a built in 3mm offset (inboard)
I actually live by Hawaii Street which is 2nd to NZ / LA's steepest hills. I'd consider this because bunny hoping pot holes is fun
works really well
This is a huge downgrade. Good if you like to run on a flat track. Terrible if you go up hills in the city
And the chain line is not straighter. It is straighter for beginners who forget to shift their front.
Triple is the one that actually gives straighter lines assuming the rider is experienced at not cross chaining.
Ive seen that brand of chainring online and the little ends to finish off the spider arms. Seems to be a popular thing now having a single front ring. I've purchased the Specialites TA with their 'spider arm' ends to finish it off, but I've still kept the 50t/34t, for my new 2023 Bianchi Oltre Comp. Love that frame and bike, it looks very cool indeed Sir
Gotta have a 2x in NYC. However our roads have a little of everything so a 1x would make me respect you even more in these roads
What would I need to buy if I have the older sram red etap to go to a 1x11? Im good with all the gearing since I’m in Florida also and never go into the small ring.
Depends on what you ride but a 52 is nice.
I have the 1x prev gen allez sprint and building a new gen with a 1x as well. I really like the fact that I don't have to shift from small to big ring at the summit of those rolling hills in Tenn. I did struggle a bit climbing long steady 12%+ grade when I took that thing to Taiwan. I have looked at the Jumbo Vismo's setup as well.. most of them ran a 48 to 54t with 34 or 36 rear on their S5. Not sure about their R5 climbing version
I'm from where Pogacar and Roglic are and here we need setup like Roglic had on the last stage of Giro. But with that setup its hard to ride in a group. 13s Ekar would be much better but still gears are to far apart for climbing and riding in group. We have too many hills 😅
I'm running 50-34 on the front with 11-34 on the back. That 34-34 gets used up the 15% and greater climbs around here. I suppose a 50 front and 11-50 on the back would work, but would it really?
You can run sram xplr 10-44 with a 44 chainring and have pretty much the exact same ratios.
How do you feel about chainlink when in the largest cog? I have the same chainring on BB30 (130 bcd) in a 46 11/34. Very noisy in the 34. I'm using KMC chain ? Have had wolf tooth in the past, and they seemed to a more quiet.
Mije is noisy too its crap
Who'd that 200' of elation work out for you?
I like the ultra wide 2x from Wickwërks. Said it also work with SRAM chains so going to test it at my new TT build. 53/34 with 10-28, if it works. But otherwise I run 11s on my roadbike.
It's so with that range. Wherever you go you have the gearing you need.
yea it is nice
I live in Florida too but use my small ring for zone 2 rides
Then of course. If you have an agenda for training then keep what you need as needed
If i ever go back to Shimano it will definitely be 1x. I love the simplicity of scram, but hate the ergonomics of their shifters
Plus dot fluid sucks
Glad I’m not the only one thinking of these things over! Good video and insight
Been running 1x in Miami since 2016. No need for a 2x down here!
Exactly you understand me lol
The argument surrounding pros being 'strong enough' to use a 1x is completely superflouous. It doesn't matter how strong they are. They want to be as efficient as possible. If 1X is more efficient, for them, it's more efficient for everyone. If it isn't, it's not. Yes, they could muscle it up a 10% climb better than we could, but they're up against other pros on 2x, so if that's the better option, they're wasting energy.
Love my 1x drivetrain!! I have plenty gears for going uphill, i have a 40t chainring with a 11-52 cassete which is more then enough. If anything ill go with a bigger chainring if i need more speed.
But any road -2% or less will make you coast at 40kmh. Gravel setup? Or bike packing?
I'm in decent shape and 1x on a road bike is not enough gear for me here. I run a 38 11-51 on my gravel bike because we have a bunch of 20% climbs and its ok for gravel but im spun out in groups and descents on a road bike. Id like it though because i hate front derailleurs.
Do someome know a good chainring about 48 or 50 teeth for sram rival
I have rival 2x powermeter but i want to keep my power meter
ccc, cross chain city, the aerodynamic gains doesn't apply on the road but only on track and there's other better things to change for a lighter bike.
I still prefer x2. Too light bikes are also not good unless you're a heavy rider. I think the x1 setup will suit the aero bike, which is heavier.
Make your choice. Tight ratios or range.
6:35 Lmao best editing of 2023
lmaooo I have to give hima raise
I need a drive train for my touring bike for my transamerica ride...I will be loaded with 50lbs of gear on my steel frame bike. I'm not a strong cyclist so need to sit and spin when climbing.
“Just get better at cycling” Woot Van Ert” 😂😂😂
New video in 2 months: "why I switched back to 2x"
Just leave the house 7 seconds earlier and you get the same savings.
😂
1x is not effective if you live in a hilly place. I run a 48/31 with the 11-34 and anything about 4-5% grade and I need the 31 to climb. With that being said I would need like a 42 front chainring or smaller if I want to be able to still climb above 5% grade. Here comes the big issue with that, when I go downhill I’m already running out of gearing with the 48 up front so a 42 going downhill would be useless! 1x are for very fit cyclists or cyclist who don’t climb.
Nice idea in theory but wouldn't majority of weight savings be countered by a larger cassette?
I mean I am already running the larger cassette
That chainstay destroying backlash at 14:27-ish
16:27 - as a percentage of time I spend in the workshop? Not much, to be honest.
fucking hard grabbbb
A one by is great for crits since no climbing also warp gainzzz
would have like to see the front mech hanger to be removed for aero and weight gains (but l run an alugear on my TT bike and 1x on many bikes like offroad and commuter. not on the training road/race bikes since it's medium hilly over here and need the range) so yeah ... would like shimano to come up up a proper 1x road groupset or at least a cool crank and not just the GRX
l do feel like the alugear chainring (54 for me) is not a stiff and l had to file down the brake pad bolt on my tt bike ...
So how does the chain run more straight with a 1x
It doesn’t. In fact it is WORSE
@@savagepro9060false.
you should say " in Florida". each time you say 1x
Hahaha
In Florida it’s ONE-BY, more BANG for the BUCK. In Los Angeles it’s DRIVE-BY . . . BANG! BANG! OUTTA LUCK!
It doesn't give you a better chain line though, unless you're in the middle of the block. As for weight saving, well you're going to need a bigger cassette which will be much heavier unless you spend big money and DA only go upto a 34T cassette, and you're gonna be grinding up hills with a 50-52 chain ring and if you use a 46 or 48 chainring you'll be spinning out on decents. I guess it could be beneficial if you live somewhere flat.
i need help on doing this i have a 2019 cinelli ..shimano 105 r588 anyone can help me?
They aren't running 1x by sheer choice. They are just afraid of dropping their chain with the lackluster SRAM front derailleurs. 🧂
Which I mentioned in the video as well
@@GCPerformance18 I saw. I wrote that before I got there though. Don't mind me, I just neg people for fun.
The climb to my house hits 18%. The shortcut has a long 24% section. I can do a 50 mile ride to a ski resort that tops out at 10 or 11%. No matter my local ride, the last 1/3 mile is always the toughest.
No 1x for me (except my XC bike with a 34 ring and 10-50 cassette.)
Also, doesn’t a 1x have MORE cross chaining? Big-big or small-small is slightly straighter than middle-big or middle-small.
And why worry about a few grams on the flats?
Yeah, for Florida, I can see going to 1x, but the day you take the bike on a trip for an epic ride, it could be painful. Maybe it depends on if you’re a grinder or a spinner.
Me? I’m a 65yo spinner. And I couldn’t compete with the pros when young. 2x for me on the road all day long.
1x chainrings (good ones anyway) have an inboard offset built into them to account for this.
But to account for what? The big cog, little cog, 3rd from the right?
The big ring will always nudge things towards the little sprocket and the little ring will always nudge it towards the big sprocket. Isn’t that what we want?
When people say that “a 1x gives an optimum chain alignment”, I think they’re just repeating a bad line. It’s optimized for what, one gear? It can’t possibly be better aligned for them all - especially at the extremes of the cassette.
I am using 1X, but 40T chainring, it's way enough for me. Do you really need 52T chainring? 52T with 10T in 90 cadence will be 61kph. I don't know man, not many people can ride this fast
It's more efficient because (1) the chain is straighter and (2) you are using the larger cogs. A lot of people think it's for max speed and focus on that too much. I'm running 54/40 in FL. Much better than the 52/36 I had.
Downhill?
I don’t think I’d do it without a rear derailleur without a clutch. Also, please enjoy riding up 12% with 50t/33t small gear. I’m not Jonas Vingegaard lol.
you dont need a clutch just a nice chainring that has some nice grabbing teeth
I don't buy the single chainring crossing less. The outer chainring is closer to the 11/10 sprocket, and per Shimano specifications I never go past the 8th sprocket either (21 on a 11-30 cassette).
For super flat terrains is OK cause you'll rarely get to the extremes of the cassette.
they are more centered then the outer chainring
There’s an offset built in.
your Elves Bike looks amazing 🤩
