The Shimano Dura-Ace ST-9001 STI Shifters received the most significant advancements in the Dura Ace group, with the ergonomics and shifting performance showing big improvements. The lever blades have a reach adjustment of up to 10mm and feature a shape that greatly improves grip, when riding on the brake hoods. With smaller, sleeker hoods, the 11-speed compatible ST-9001 STI units deliver improved ergonomics for better rider comfort and control, with reduced lever stroke and lighter action. It now takes even less effort to shift, with the lever throw, or distance that the lever needs to move in order to shift now reduced by 30%. 365 g.
