Designed to provide you with a better sports’ bicycle experience the PRO Cassette Removal Set combines two of the tools needed for cassette installation and removal. The PRO Cassette Removal Chainwhip features an 11-speed compatible chain and is intended to hold the cassette firmly in place while using the PRO Lockring Tool to loosen the cassette’s lockring. The Lockring Tool meanwhile is also intended for tightening the lockring which holds a cassette in place on your hub. Both tools feature hardened steel constructions, long handles for increased leverage and dual compound grips, for comfort.
