BBB Cycling BTL-125 ChainChecker
The BBB Cycling BTL-125 ChainChecker is a 30g chain wear indicator for 7- to 12-speed chains that doubles as a mini multi-tool, adding 5, 6 and 8mm allen keys, a valve tool and integrated chain hooks to hold links during assembly. It suits any rider who wants to catch chain wear before it eats the cassette, with a few extra functions along for the ride.
- Check your chain once in a while to make sure it is not worn out. But, our Chainchecker is more than just a chain checking tool. It also contains 3 allen keys, a valve tool, and can be used as hooks while working on your chain. It is just a chain tool, but so much more with the added possibilities!
- Integrated chain hooks hold links during assembly
- Added valve tool and 5/6/8 mm allen keys makes this a unique multi-tool
