Birzman Specialist Chain Whip

An eye-catching streamline silhouette that is a Birzman signature design, this Specialist Lockring Wrench is compatible with 5-12 speed, 3/32" single speed and Campagnolo 13 speed cassette sprockets, and is equipped with a fixed-gear lockring wrench.

Modular extension bar is available (BM11-ST-MHE-K) to increase the leverage of the wrench.
