The SHIMANO DURA-ACE ST-R9250-Left 12-speed is the pinnacle of Shimano's road cycling technology, offering unrivaled performance to serious riders. This Dual Control lever is part of Shimano's fastest groupset ever, the 12-speed DURA-ACE R9200, and is designed to push the limits of speed, precision, and control. Built for professional and competitive riders, it provides rapid, wireless shifting and superior braking performance while being lightweight and ergonomic.
Another notable innovation is the Di2 wireless shifting platform, which allows for rapid and accurate gear changes without the use of traditional shift cables. This enhances the bike's overall aerodynamics and makes maintenance easier. Furthermore, the battery life is outstanding, with the CR1632 shifter batteries lasting up to 1.5 to 2 years before needing to be replaced, assuring consistent, long-term performance with minimal maintenance. The ST-R9250-L lever, designed for use with the SLR-EV rim brake system, provides tremendous braking performance when combined with the DURA-ACE BR-R9200 or BR-R9210 calipers. This system has a twin symmetric pivot design, which increases braking power by up to 36% over prior models, providing improved modulation and control in all conditions.
