Chain checker
Excellent tool nice & easy to use a must for all push bikes at least e-bike owners should have one to keep an eye on their chain. Replacing a chain cheaper than the cassette & cog at the front

Better quality than the photos suggest
This is a nice tool. There is a knack to using it correctly so a degree of mechanical sympathy is required but most careful people should have no problem getting an acceptable indication of chain wear.The cam design of measuring minute distances is clever and the materials are all good quality.It comes in a flimsy plastic tray which I think is a shame. The pins are a bit too fragile to keep this loose in a toolbox so it would have been nice to get a decent cardboard or plastic box to store it in.

Simple but effective
Love it, simple tool that tells you if your chain has worn. Not cheap but feels quality and that it will last.
User
Very useful
This is much more useful than the simple chain wear indicators if you’re faced with a variety of multi-gear chains. It is quite expensive but generally you get what you pay for particularly with tools. It’s built to last.
User
New chain shows worn
Checked a brand new chain with this and shows already worn, probably never use this due to this factor

The Little Tool That Saves Big Headaches (and Cash)
This Park Tool chain checker is simple, awesome, and worth every penny. It only does one thing, tells you when your chain’s worn out, but it does it perfectly.If you ride regularly, this thing is a must-have. It’ll save your drivetrain, your wallet, and your pride when you realize you’ve been grinding miles on a chain that’s basically a worn noodle.I’m a garage-maintenance kind of cyclist, so this one lives right next to my torque wrench and caffeine stash. Doesn’t make coffee, doesn’t look flashy, just does its job better than I do mine on hill repeats.10/10 — small tool, big value.
