Abbey Bike Tools Decade Chain Tool

Abbey Bike Tools Decade Chain Tool is a professional chain breaker designed for consistent drivetrain service across modern bicycle chains. Built with machined aluminum handles and a cro-moly steel body, it uses a shock-rated tool steel pin capable of more than 10,000 chain breaks while maintaining precise alignment during chain installation or removal.

Compatible with 9–13 speed chains from Shimano, SRAM, and Campagnolo, the Decade Tool also includes a threaded backstop stored inside the handle for peening Campagnolo 11 and 12-speed chains. A PVD-coated lead screw and large ergonomic handles help deliver smooth operation and long service life in professional workshop environments.
