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.
