@@skm9420 When you're selling snake oil you're allowed make whatever claims you like. Ceramic bearings also don't necessarily last longer as most of them use the same steel races as all steel bearings, which wear faster on ceramic ball bearings. It's mostly serving the world as a means of getting the money from the dentist demographic back circulating in the economy. Have a look at Hambini's channel for a proper discussion of all the market wanketeering related to bearings with plenty of justified swearing. Also you'll hopefully never have the misfortune of buying a Cannondale frame or a SRAM BB after he goes though just how badly the basic engineering is done in these products - I'd add E13 to the list as well - they can't seem to spec a bearing that doesn't seize at the first sight of mud on their BB's or chainguides.

Hey peeps! First off all massiv thanks for the ton of content you guys put out! So, thanks ladies and gents at pink bike! But one thing to this video in peticular. I can't confirm that stretch on a bike chain is a misconception. They do stretch in length. And it is very obvious that the do. To make it valid i measured it the other day and they stretch quite not only a bit. And the stretch they have is not caused by the wear of the bolts. If someone wrote about the same i am sorry. i have looked for it in the comments. Thanks again! If you want we can talk about it some more.
If you're running a small chainring and a long crank (Say 175 mm with a 28T chainring, which has a circumference of 14" (chains have a 0.5" pitch) and a radius of 14"/(2 pi) = 2.23" or 56.5 mm, the law of the lever gives you a 3.09 force multiplication between the pedal force and the chain force), and you weighed 220 lbf (100 kgf or 981 N in non medieval units), you could apply a static load of 3*981 = 3033 N to the chain by putting your whole weight on the lead pedal with the back brake on (Incidentally you can both feel and see chain stretch when you do this, especially if you run a singlespeed where the bottom run of the chain will go visibly slack as the pedals load up - this is elastic stretch though and the chain springs back to its original length as soon as the load is removed - other parts of the bike are bending and stretching to carry this weight too, so less than half the slack you see is likely to be actual chain stretch. A big landing where your lead foot carries your weight onto the freewheel could easily triple this, which believe it or not gets you bang on 9100 N, the lower limit for the tensile strength of the chains in the test quoted in the video, so while normal pedaling will only break a chain if you're a powerlifter running SPDs (Squatting 3 times your bodyweight isn't unheard of in powerlifting circles, especially when you don't have to bend your knee anything like as far as for an actual squat) or the chain is defective (or shifted under load), shock loads can absolutely break perfectly good chains. I should also mention that chain rollers generally don't reduce in diameter as they wear as claimed in the video anything like as significantly as they reduce in thickness, giving the distinctive rattly grinding noise a worn chain makes as the rollers rattle on engaging with the sprocket teeth. This however isn't a problem in wear terms unless the chain pitch also changes. This happens where the chain pin rubs against the inner link plates in the chain, wearing a notch into the chain pin and wearing the inner link plate hole into a slot. Note that only the inner link plate pitch increases as the chain wears as there's no sliding between the outer link plates and the chain pins and therefore no wear. The upshot of this is that if you run an even number of teeth on all sprockets and the chain shifting pattern always puts inner links on the same tooth of every sprocket every time, you can have a drivetrain with every second tooth worn to the new pitch that still runs skip free for much longer than the same setup with odd numbers of sprocket teeth. Also have a look at Shimano's chain wear checker for a tool designed to correctly measure wear on chains by preloading the rollers to get a pin to pin distance rather than almost every other manufacturer's version which measures roller wear and pin to pin changes combined, giving a false impression of the wear level of the chain.
I love videos like this because I've taken chains off my bikes where the chain plates then selves have elongated holes and tears in the steel. Just because it isn't likely you can't say that it's not possible.
Love the explainer series! Nice job levy lol I’d like to see a educational video on fork offset. I ride an ibis Ripmo, which we all know was all the hype with the 44mm offset (now yeti is running 42mm offset) but for years the standard was 52mm if I’m not mistaken? I’d just like to know more on the theory behind this. Thanks guys and keep up the good work!
If chains dont stretch, how do you explain the chain getting more loose after a while of use on my single speed and my dirt jump bike? Also, chains dont break? Again, on my dirt bike (single speed) my chain cracked multiple times even with no shifts. Might be because it was a halflink chain tho.
The side plates of a chain don't stretch. As explained in the video the bearing points at each end of the links wear, resulting in an effective increase in length. The chain hasn't stretched in the sense that a rubber band might, it has worn, and play the worn links accounts for the increase in length. Similarly the tensile strength of the side plates is way higher than the force that even the beefiest rider could exert. Chains don't break in the sense that there is a structural failure and a part of the chain has actually snapped. Failure is due to a pin pulling out of a side plate. Either due to incorrect assembly (Not uncommon in the past when derailleur chains didn't have quick links. A new chain would be installed by a mechanic using a tool to press the rivet pin into the side plates to join the ends of the chain up. If not done correctly the link at the join may be stiff, or worse the rivet may not be correctly fitted in the side plate and pull out under load.) On modern cycles, all rivets are factory installed and should with near 100% certainty be correctly fitted. As explained in the video rivets can be dislodged by clumsy gear changing under full power, eventually leading to the rivet pulling out of the side plate.
The definition of stretch is "capable of being made longer or wider without tearing or breaking." So despite how it's actually happening, the chain is indeed getting longer - therefore "stretch" is an appropriate adjective to describe what's happening.
Please explain how different rear suspension linkages with the same shock stroke length can end up with different amounts of rear wheel travel and vice versa
From what I heard, the ordinary (what some call a penny farthing) had the huge wheel simply for gearing advantage. Before gears and chains, a bigger wheel meant a faster top speed.
Exactly so. A big wheel meant a bigger (higher) gear thus more speed for the same cadence. On the ordinary cycle, this meant that your gearing was dictated by your inside leg measurement. You could perhaps ride a bike with a smaller gear, although this would effectively make your saddle too low, but there was no way you could ride a higher gear, your feet just wouldn't reach the pedals. Chain drive meant that pedal cranks and drive wheels no longer had to turn at the same speed. We still talk about gearing in terms of the equivalent ordinary cycle front wheel size, (in the UK at least). When we speak of a 100" gear, we mean the the chain ring to sprocket ratio is such that our 700c wheel is effectively multiplied in size to carry us the same distance as a 100" wheel on an ordinary would for each turn of the pedals. (Do you know anyone with a 50"+ inside leg? Me neither!)
Yes the wear on the chain is the bigger issue but all chains do stretch. It is subjected to a force that pulls the chain in an axial direction which strains the material i.e. stretches the chain. Although this number could be very small especially with a higher end chain with harder steel
Chain drive is also lighter and less expensive than belt or shaft, a big advantge on bicycles. The light weight and efficient power transfer is also why chain drive is the norm on any motorcycle where performance and light weight is important (basically any dirt bike and sport bike), the low cost of chain drive is why it is popular on less expensive motorcycles, it is also much cheaper to fix if something breaks.
Great video. What about cockpit setup? I know often its personal and it can be a big topic as there are a lot of variables. I run a DH, enduro and an ebike and have improved ride feel on them all by shortening stems, moving and changing seats adding riser bars, changing to One Up carbon bars to eliminate vibration , changing grips, using shimano brakes with good lever ergonomics.etc
This is a wonderful video, and I’m really enjoying this new series of explaining it videos. I have a question for you Mike, do you know is there a way to close a SRAM gold eagle 12 speed chain without using a quick link? I guess I’m asking is there a way to pin it closed.
ASD I believe it works the same with Sram but there is specific joining pins with pointed ends. If you got a new chain they should come in a tiny bag with some standard extra links
Luke Schlieper So my chain broke about 12 links after my split link. I want to put it back together without using a split link again in case it gets screwed up in the derailer
Yes, the plates don't stretch, but pin and roller wear manifest as a chain pitch that measures longer, which looks like, and everyone calls, "stretch". Educating about what causes the "stretch" is fine, but we don't need to abolish the term "chain stretch"
The chain stretch thing was hilarious too. The chain doesn't stretch, it just gets longer. Ehh ok. That's what us dummies call stretching but nvm that.
@Pinkbike... Could you please go into how US import taxes based on wheel size affected the wheel size of your mountain bike? (I will give you a hint here, 29ers didn't get adopted by the bike industry because they roll over obstacles better, they got adopted by bicycle manufaters to get around US import duties on 26" wheels and make more profit per bike.)
Someone could definitely crank 1800lb to a chain. There are leverage ratios with the crank length, so you could cut that in half to 900lb pedal force. Get a big dude and have him stomp on the crank, and he could certainly create a 900lb impact force, an impact force that's liable to snap a chain more readily than a static load. That's considering a perfect straight chainline too.
I would say that my headset is the component I think about the least. Something I never think about until it catastrophically fails (which I don't think has ever happened in the nearly 20 years I've been riding mountain bikes.

I would take a look at the tension held on the timing chain. too slack, too tight? I dunno, not my bike. but it IS my 2¢
@@simonfarr8670 Thanks. Set as per instructions + tried slacker and tighter tensions. Only thing I can think is frame flex - I'm a big old lump at 6'5".
0:29 the ONLY reason i am about to watch this is that the shape of the chain link wasn't straight. (in thumb nail)
Also it looks like it has a crack in it....WTF !
Never seen a chain that the links had a bend to them.
Curious as to who makes these type of "curved" chain links !
Watched the video, DON'T care for a history lesson, Video is a click bait cause of thumb nail ! ! !
Hydraulic brakes, dropper posts, and bb’s
That's not how Ice Cube got his chain snatched.
