It is intended for use with Shimano road groupsets such as Ultegra, 105, and Dura-Ace 11-speed systems, providing precise rear shifting control and hydraulic braking. The shifter lever is made of composite material, offering durability while maintaining a manageable weight of approximately 327 grams installed.

This lever supports hydraulic disc brakes using mineral oil, delivering solid braking performance with the convenience of hydraulic actuation and reach adjustment of up to 10mm, accommodating various hand sizes. It’s engineered to integrate seamlessly with Shimano mechanical shifting systems while operating hydraulic brakes. It offers reliable real-world performance for road cyclists seeking an upgrade from mechanical or rim-brake systems to hydraulic braking without sacrificing Shimano’s trusted shifting precision.
