Pedros Pro Chain Whip

A compact cassette-holding tool with a chain-retention hook and an integrated fixed-gear lockring wrench, suited to portable workshop kits.

This 6451310 model is listed at 270mm and 225g. Its hook fits sprockets up to 18 teeth and the lockring opening is intended for 41-42mm outside diameters. Chain/cassette compatibility remains model-specific; the newer II tool's drive and dimensions do not apply.
