The Twisted ShifterZ 9/10 Speed Super Kit is a chrome product designed to enhance your shifting experience. This kit is specifically made for non-splitter 9 and regular 10 speed shifters, and includes an adapter installed on a new Eaton Fuller shift valve. It replaces older 'D' shaped handle setups and current 'sloped' type handles, fitting most makes and models. Additionally, most Twisted ShifterZ shift knobs require a new adapter, which can be reviewed and purchased separately. Upgrade your shifting with this practical and versatile kit.
