To alleviate poor shifting and uneven drive train wear, most manufacturers recommend chain replacement at or before 1% stretch. Now you can quickly and accurately determine the wear and stretch of any chain with the Park Tool Chain Checker. Simply insert the Chain Checker's pins into two links, press the swing arm gauge tight, and then check the gauge window for an accurate reading.

Gold standard of chain checkers

This chain checker seems to give the most accurate sense of when to replace a chain. I have two bar-style checkers, which measure different from one another. This one reads closer to the Park CC 3.2 and always reads out above the recommended limit for Shimano chains just about when the chain gets noisy and can't be quieted by lubing. It's sold at descent price and may save you on bigger bills for replacement cogs. Keep riding!

Just what I needed

Not a lot to be said about this tool. It dose exactly what it claims. BTD has the best prices and I end up buying things more often so am I saving money? I doubt it but thats cool. Keep up the good work.

This Checker Tool is accurate and easy to use.

I generally take good care of my bike chain with a cleaning and lube every 2wks. during riding season.

I had 4500mi. on my last chain before I bought this checker and found I still could have added a few more

miles but I replaced anyway. This tool is very easy to use. Happy with my purchase.

Really useful little tool

It really is made to check the stretchwear of your chain, so it's appropriately named. Very simple to use, and it appears to give a precise measurement to let you make a decision about replacement of your chain. I haven't used the other chain checker from Park (CC-3.2), but this one seems much more accurate by design, so I opted to spend a bit more for it. Park Tool tools don't typically disappoint, and this little guy continues that tradition for me.

Saves time and money

The options are simple. Either you go to the bike shop when you think your chain is at the end of its life to get it checked or you spend a few bucks and buy this tool. Going to the bike shop is always fun but it will cost you time and money (not including the money spent while at the shop just because you are there and there are lots of cool stuff to buy there). Besides, having the tool handy means you don't wait till it is too late to change the chain and you don't risk ruining the cassette and even the crank.

Good tool!

In general, Park tools always seem well built. This chain checker is more than just a 'pass/fail' tool, it gives you an idea of how the chain wear is progressing if you use it several times over the life of the chain. The point of this tool is to replace your chain before it causes undue wear to your cassette - which is of course MUCH more expensive!

Park Tool simplicity and durability

This is the same tool that my bike shop uses whenever I bring it in for a check up or tune up. I figured it was time to perform maintenance on my own and understand my wear rate over time during summer and winter seasons.

Worth the few extra $$

I like be able to tell how close my chain is to needing replacement. Better than the drop checker, and worth the few extra $$.

Small, simple and brilliant

While some Park Tool items leave you wanting something a little better this item is the better.

It's small and simple to use. Easy to clean and very, very accurate.
