Runwell Japan Checker

42.00 SGD

A special tool for NJS-certified chains co-developed with a Keirin bike inspector. 

CHECKER is an innovative tool to check the 6mm square nut attached to the joint of truck chains such as IZUMI V-Chain. The small nuts on this type of track chain can loosen and sometimes result in loss if not properly tightened.

This CHECKER is a professional tool that allows you to easily check and tighten nuts just before a race, road practice, and during break times.
