I need to check chain wear, are these short chain wear tools good to use?
Here is the list of them: ebay.ca/sch/i.html?_from=R40&_nkw=Bike+Chain+Wear+Indicator&_sacat=0&_sop=15
They look like this, I plan to get this one if it is good: ebay.ca/itm/404228716615
Is it too short? arnt they suppose to be longer so they would be more accurate for measuring chainwear?
I used to use a ruler to measure it, but i always keep putting it off because it seems like a hassle to measure chain wear this way.

I would just post the link as normal. To do that just get to 5+5 posts and you will be able to post links there are a ton of awesome active threads to get involved with to get those posts.
These would be the chain tools I would recommend:
https://www.parktool.com/en-us/produ...dicator-cc-3-2
https://www.parktool.com/en-us/produ...category=Chain
https://www.rohloff.de/en/shop/produ...2f986c5ff0b123
I would probably just avoid stuff on eBay especially new stuff. Older vintage and some used stuff is cool but get new stuff from an authorized dealer.

I'm not looking at your links, but in general, they tend to show more wear than actual.
Mine reads about .25% high, but I allow for that. It works fine for a quick check on good chains.
When in doubt, I get the ruler.

They're all decent, though can be prone to false high readings.
Buy yourself a steel ruler. Use it by pulling the RD back to slightly tension the lower loop and measure pin to pin. Stretched to needing replacement is 1% or 1/8" over 12". Half that over 6". Many people replace at 0.5% so consider the range between those as optional replacement.

I use the chain checker tools to know when I'm getting close to a worn chain and then a steel ruler for the final, more accurate measurement. The advantage of a chain checker is that it's quick and easy.

Agree with FBinNY 's reply, but my added observation is if you wait until the checker says it's really worn, then it's likely you'll need to replace the chainrings and the cassette/freewheel as well, as they will have been damaged by the worn chain.

I like the Park Tool checker. It's convenient and accurate enough for my use. I find measuring with a ruler fiddly and I need more light and magnifier glasses. Either way works.

I have 3 chain checkers. I find the Park CC-3.2 is the most accurate. My ProLink one shows a new chain to be 50% worn and my KMC one shows a worn chain to still have some life in it.

They are good for a quick check. But some brands might not have the manufacturing quality control to ensure that only models of their tool that are within the tolerances needed to be able to give decent results. (might need to figure out how to word that better, but you should get the gist)
When you start showing some wear with them, it might be a good idea to double check with that steel scale till you know if the chain checker is accurate enough or not. We talk about wear in percentage of length. And all bike chains with very few exceptions are 1/2 inch pitch. I think many of us would replace a chain when the pin that should be at 12 inches is measuring 12-1/16 inches.

I'd think so, but I don't know so.
Do you think that everyone making these holds them to the tolerances needed to be reliable? Low price tools usually come with a corresponding lack of checking what's coming out the door. Or that's what I can only imagine for the times a bought a cheap tool that worked properly and another of the same tool that didn't work properly or stand up to multiple use.

Yes, chain checkers are useful and accurate…enough. I’m not a fan of that particular model and would suggest going with a Park CC-3.2 or, if you want to over complicate the process a Park CC-4. There are similar versions of both out there but I probably wouldn’t buy an Ebay knockoff.

No, your shared link is waaaaay too long. Do not include any following characters, beginning with the "?"

Also might need to point out that the one in this link... https://www.ebay.ca/itm/404228716615 is really for chains with less speeds on the rear. Most people with 11 speed or greater chains that care about it seem to replace them when they are 0.5% or more worn. That checker only measures 1.0 percent or 0.75% wear which BITD of fewer rear cogs was acceptable by many. I doubt that I'd let my chain go to the 0.75% that is the smallest amount it can show with out more guessing.
Also with that type checker, some SRAM 12 speed chains have larger rollers. So the wear from checkers that measure just the distance between the opposite sides of two rollers will be wrong. If the checker measures the distance between the same side of each roller then it should be okay.

Just curious, why are you pointing to a Canadian listing that clearly says Does not ship to United States.

When these chain checker tool arguments arise, does anyone else scratch their head at the comments that say chain checker tools are inaccurate, and steel rulers are the only way to go? If using a steel ruler is your preferred method, more power to ya. But why would an otherwise very reputable tool company suddenly jeopardize their reputation and put their brand on less-than-accurate tools? If the QA in the tool’s production is questionable, why can the QA in production of a steel ruler be questionable? — Dan
