I bought a Trek Singletrack 930 brand new in 1996. Put tons of miles on it, on and off trail. FFWD to 2008 and I'm using it as my commuter to my job at a bicycle shop. The mechanic put that chain wear checker on and it went completely flat against the chain. The cassette and chainrings have worn with the chain as well. I have no issues withe gears skipping, even under power climbing a hill in near top gear. Not saying this Park tool doesn't work - just saying that when everything has worn together in over 10k miles of riding, it somehow still works together. If the chain goes, though, pretty sure I'll have to replace everything, lol. Best bike I've ever owned.

I never found these types of tools to be accurate. I wore out drivetrains using a "fit gauge" like this one. Campagnolo gives a precise dimension for a worn chain and I use a Mitutoyo caliper to measure per Campy's instruction. The difference between a new and worn Campy chain is only about 0.020" (20 thousandths, 0.5 mm). So judging the "percent worn" as the weeks go by is much easier measuring it for real. Good-enough calipers are hardly more than the price of a chain, and you can use the calipers for home projects and vehicle maintenance.

This was excellent. I love that you described exactly why the CC-4 is preferable. I worked with the mechanic who invented this type of chain checker in conjunction with Shimano, back at the Bike Gallery in Portland, OR. The other options at the time were not nearly precise enough. We used the prototypes in the shop and immediately got much better outcomes for our high-mileage riders, all-weather commuters, and big-hammer racers. It's one of many tools invented by the only genuine mechanical genius I fixed bikes with in a 20-year career. Park copied many of them. But if it leads to riders having better experiences riding their bikes (and supports always-beleaguered mechanics), that's what matters. Thanks Ollie!
@ltu42 19 күн бұрын
CC-2 is plenty precise enough, but it lumps the elongation of the chain (which is important) with the roller slop (which is not). CC-4 pushes the rollers in the same direction by virtue of that finger pressure, thus excluding roller slop from the measurement. Ollie did not explain that.

Ollie is the new Sheldon Brown with his chain expertise. Another good way to visualize chain wear is to hang your old chain next to a new one, a long steel ruler is also good. I just replaced one on my ti mtb, it wasn't worn out but was stretched enough to not bother converting it to wax, much easier to start with a fresh chain.

Zero Friction Cycling looked at chain checkers, tested them, and found the Park CC-2 is wildly inaccurate. As the Escape Collective noted in a Geek Warning podcast, it's pretty well known that the CC-2 is not the checker to use if you want to correctly and accurately measure chain wear. I'm not sure why you guys think it's worth showing to viewers.

ZFC shills for stuff that they make, they aren't really objective. They claim on their site that their Zero Lube lasts for 1100 km per application which makes it the longest in the world. Both Chain L, Phil Wood oil and pretty much any mineral oil based lube can easily go over 2000km per application. The stuff ZFC makes is good for racing, but it's not the best for everything.

CC-2 is not useless if you understand that it's a relative measuring tool, not an absolute measurement device. I use my CC-2 to check each new chain, then monitor the chain wear going forward. I also have a set of Mitutoyo calipers for more precise measurements, but the CC-2 is quicker and gives me enough accuracy to know that a given chain is or isn't at the end of it's service life.😁

@@___Bebo___ , you haven't really paid attention to ZFC, have you? ZFC doesn't make anything, so that point is dead in the water. ZFC does testing and sells what does best in their testing. Testing from other sources confirms ZFC's testing protocol. If you think ZFC is shilling, you should send an email to them asking them about that. They're more than happy to discuss their testing protocol and what they sell. Oh, and there's no product on their site nor in their test results called "Zero Lube". You're making stuff up. It's also worth noting that ZFC has highlighted the fact that their testing "kms" or "miles" are not equivalent to road miles. Moreover, they're not measuring how long the lube stays on the chain, they're measuring the wear rate of the chain. There's little good that comes from leaving your pet lubes on your chain for 2000km, because with the grit that accumulates in your wet lubes, your lubes will turn into nice grinding pastes. You really should pay attention to what the man says. Clearly you haven't.

I've missed the point when my SRAM Eagle 12 speed chain went from almost no wear to, suddenly, 0.8% wear (as measured by digital calipers and by the total chain length). I'm glad to report that with the new chain there is no skipping. I think the recommendations for 0.5% on 11 and 12 speed drivetrains are somewhat conservative.

The Park Tool CC-4 is a great tool. I'll disagree that the tool needs to be inserted at an inner link and not at an outer link. The CC-4 I have has a diagram right on the tool that shows inserting it between outer links. But it's a moot point. It doesn't matter if the tool is inserted between inner links or outer links. The tool pushes the rollers tight to the same side of the pins at all three places it's designed for. All the links have the same spacing (outer links don't wear out, the wear is inside the rollers and mostly where the pins contact the inner links) so the wear will be the same no matter where on the chain you place the tool, EXCEPT...if the tool bridges the chain's master link, then if the master link has worn differently than all the other links in the chain, it'll affect the chain stretch measurement. The other Park Tool in the video is not recommended because it pushes the rollers in opposite directions, which can result in showing the chain has more wear that it actually has, plus that tool only spans a few links. The CC-4 spans a lot more, reflecting the cumulative effect of many links, not just a few.

SRAM AXS chains should be replaced at .8% wear. The manufacturer’s technical guide specifically indicates: “Flattop chains last longer than 10/11 speed road chains. Replacing a Flattop chain too early may prematurely wear the chainring and cassette.” As a side note, they are very durable, I wipe the chain with microfiber cloth, top up Silica SS drip-on wax once a week (=every 300-500km depending on dry vs wet conditions) and get easily 16K km out of a Force 12s flattop chain.

One method to extend the life of your cassette is to run two chains, swapping at regular intervals. Winter commuting in NE Scotland, I swap chains over every week. In summer It would be every three to four weeks. I managed to get three to four chain sets per cassette by changing them when 0.75% worn (9 speed cassette) over two to three chains when running them singularly.

The double pin checkers are more inaccurate because they don't account for roller wear. The Park CC4 is actually a copy of the older Shimano TL-CN40 chain checker, which does account for roller wear. It's far more accurate. They're also higher quality tools with better tolerances because they're laser cut and QC'd... the cheap chain checkers you find everywhere are just stamped steel. Of course there's also the old school method of taking the chain off and using a machinist ruler on the center pins. Regardless of the CC you use, the rule is if you drop it on the floor, it's garbage because it has lost its calibration.
@peglor 22 күн бұрын
Good to see more encouraging of the corporate line of saying people have to waste their time and money while increasing the environmental impact of their cycling by replacing slightly worn chains for no good reason. The problem with this whole idea is that If you pass the wear limit even slightly, which can happen mid spin, especially if the spin happens to be in wet, gritty conditions, you get skipping gears anyway. I've had the replacement chain skip when the old chain was just on the replacement interval as determined with the more accurate Shimano chain checker (Most chain checkers don't account for play in the rollers in their measurements, giving premature replacement intervals). This then leaves you with the choice of either letting the chain wear into everything to get some value out of the cassette and rings which already skip with a new chain, or buying a new drivetrain anyway. Letting everything wear in together has given me no skipping gears ever in 30+ years of doing it (Trying the chain replacement was a brief effort a couple of years ago, which failed precisely because it added work for me and did no make the drivetrain last longer). Turns out even when the chain is worn to the point the rollers literally fall off it, the gears still don't skip - but I tend not to let it go that far as it's not exactly quiet at that point, and produces less waste for (hopefully) recycling. Since a compete drivetrain will run for 4 or 5 times as long as the chain replacement intervals with no intervention at all, apart from basic cleaning and lubrication, it's cheaper to do things this way in cost terms and environmental cost, and cheaper again if you value your time.

Ollie waxes his chains. It looks like he has left the chain in his hot wax pot too long as when the wax cools it will stick to the outside of the chain. You have to remove the chain from the wax when it's hot, the wax stays in the pins and rollers, it does not run out. The wax on the outside of the chain looks dirty because dust will stick to the wax surface (lubricity additives such as tungsten disulfide will also make wax which is white darken) but as the wax is hard ie not fluid like an oil, surface dust does not make it's way into the pins to wear away the chain, resulting in much much longer drive-chain life.

The CC-4 chain checker is not cheap. You can buy two or three chains for the price of the tool. Anything more than a 9 or 8 spd cassette is a money pit. Stick to 5 or 6 spd and save money. Better still go single speed. The CC-4 is better because it takes up the slack in worn rollers that do not contribute to chain "stretch". The other chain checkers do not allow for this and they indicate more than the real wear. You could be tossing a chain that is still good.

And the problem is that the rollers within the links are going to start wearing out regardless of the chain stretch. This is why you should change your chain regardless of the chain stretch.

I don't know how do you use mathematical expression of percentages but in my opinion if you use percentage there is 💯 % of one whole unit. That means if you want to say half of sth (1/2 of whole piece) it is 50 % not point five (0.5). And the same is about 3/4 of one piece it is mathematically 75 % in percentage (not 0.75% as you say). Because you and the tool speeks about extension by one chain segment not percents. But anyway. Thank you for the correct way how to measure the chain! I think a lot of riders keep one of those tool but not everybody knows how to use ut in right way 👍
@simonm1447 16 күн бұрын
His mathematics are right. A new chain is set at 100,0% without wear. A worn one with 1% wear will have 101% of the length compared to the new specs. 8 or 9 speed chains can be driven until 1% wear, while more modern 12 speed chains are considered as worn with 0,75%. If you measure it with a ruler instead of such a tool it's the same, a new one has 25,4 cm over 10 double links while a worn one with 1% wear has 2,54 mm more

just measure it with a good ruler. 10 double links have 254 mm in new condition. With 0,75% wear it has 256 mm. That's very exactly to do and it also avoids the error the play of the roller gives you to a normal chain checker you stick into a chain

My only question is, with 11 speed usually first it will only drop to 0.5 at one place, most of time around the quick link but if you measure at several places on the chain other points are still fine, maybe with your hands applying some force it will go in but from it self it won’t. So when is it really 0.5? Should I replace the chain when it drops at one place and nowhere else or at this point still some life left in it and it’s fine until it starts to drop in several places?

As an engineer, I guess that Shimano have done durability testing and have shown that cassette and chain ring wear becomes non-linear (accelerates) beyond these "wear limits". The theory is that you replace the cheaper chain rather than the more expensive cassette and crankset. However, if you use cheap Sunrace cassettes and Ali Express cranksets you could just wear them all out together as an "assembly" as they all cost roughly the same amount and not get the same slippage till a bit later and they are worn to the same degree. Don't blame me if you go over the handlebars though 😁

I don't know the extent of your knowledge of chain waxing but I think you are being sarcastic. If the chain is a waxed one the apparent "build-up" on the chain links could be excess external wax resulting from leaving the chain in the molten wax too long after the wax heater had been turned off. The wax will start to cool and solidify so that when you lift the chain from the molten wax, instead of the wax that is on the exterior of the chain running off, it will stick to the chain. The hot Wax that is inside the pins and rollers does not run out. The excess exterior wax will simply flake off when the bike is ridden.

Some confusion about where to put the rear pin of the CC-2. You say between the inner links, and yet a Park Tools video from seven years ago, shows it being used between outer links. A couple of years ago, Alex did a video and he put the pin with the measuring device, the front or left hand pin in between two outer plates, which means that the other pin goes into two INNER plates. Surely it doesn’t matter as long as one pin is between two inner plates, ant the other is between two outer ones?

If your cassette or crankset have worn to some level, you will also find you can´t fit your new chain on them. That is what my bike mechanics told me after I failed to replace the chain by myself. Now I just take his suggestion: Keep riding until your cassette or crankset can not grab your chain tight and correctly, then replace all of them. Every day I ride 30km to work and it takes me at least 6000km to do such replacement (I don´t wax the chain because wax can not hold the wet winter weather in north Germany). Such tool is totally useless and just waste of your money. Don´t be victim of bike industry.

Aww, poo. A chain wear tool? That's one more thing for me to worry about (😁). Fortunately, my grotty old bike is not the kind of glamorous recreational thing that appears on proper cycling channels such as GCN. It's a 55 lb steel-framed monstrosity from Halfords, now laden with panniers and racks for carrying groceries. It also tows a homemade trailer which can haul 150 lbs of gubbins, dooh-dahs, wotsits and stuff. I'm not proud of it. It's a tool. The bike cost me £130, brand new, over 15 years ago. [A direct replacement would cost precisely the same - £130 - which is probably less that most peeps reading this spent on their carbon-fibre and titanium water bottle mount...] I ride 70 miles a week, every week, in West Yorkshire in the gloomy north of England, where every wind is a headwind and the hills only go up, never down [joke]. The bike's done well over 50,000 miles. I'm skint, so the poor thing gets treated appallingly. I keep a chain on until it start missing gears. Then, rather than swap the chain, I just switch to a different gear and keep pedalling. I currently have access to three gears from a total of eighteen, so it may be getting close to the time when I consider thinking about buying some new bits... Yes, I'm a bad, bad, BAAAAD girl. Um... is waxing a chain anything like waxing your legs?🤔
