Park Tool CC-4.2 Chain Checker

$ 17.95

Tools are not returnable All sales are final on this item.

An old, worn chain can prematurely wear out your drivetrain components, causing more problems that can easily be avoidable.

The Park Tool CC-4.2 Chain Checker is a drop-in style gauge that strategically contacts the chain in three places, accurately measuring a length of chain and quickly takes the guesswork out of determining when chain replacement is necessary. 

 

This tool works on all chains, but the 1.0% wear mark indicates the standard recommendation for chain replacement on a fixed gear/single speed drivetrain.
