Birzman Sprocket Remover

The chain-whip attachments on the Sprocket Remover grasp onto the cassette cogs on 7-12-speed drivetrains. Use alongside a Birzman Lockring Socket and Wrench, the Sprocket Remover keeps the cassette in place so that the lockring can be loosened and removed. The spring-loaded design makes one-hand operation quick and easy. Compatible with 7-12 speed sprockets. SPHC steel / High polymer 300mm size.
