Shimano Dura Ace ST-R9250 DI2 Rim Brake Shift Lever Set
Product Details
Finely crafted, the Shimano Dura-Ace ST-R9250 Di2 shifters deliver precise 12-speed electronic shifting performance with refined ergonomics and ultra-lightweight construction. Designed for Shimano’s latest Di2 system, they provide fast, responsive gear changes with a crisp, tactile lever feel that enhances control and confidence in high-performance racing environments.
The redesigned hood shape and textured surface improve grip and comfort across multiple hand positions, supporting stable handling during aggressive riding.
