Topeak Ninja C

The Ninja C chain breaker can be discreetly stored in the handlebar (suitable for diameters from 16.5 mm to 20 mm) for a clean look, yet is quickly accessible when needed. It is suitable for all multispeed and 11-speed chains and also features a compartment for chain pins, a chain hook, and a 4 mm Allen key for easy operation. The underbar must be straight and at least 70 mm long.
