Shift/Brake Lever Set Shimano 105 Di2 R7170 Right, 12-Speed

The Shimano 105 Di2 ST-R7170 + BR-R7170 right 12-speed shift and brake set brings electronic Di2 shifting to the 105 level, delivering precise, fast and intuitive rear shifting. The wireless cockpit design enhances aesthetics while maintaining lightning-fast and reliable performance.

The Dual-Control (STI) ergonomics are inspired by DURA-ACE, offering a compact and comfortable grip. The raised hood peak and extended lever body improve hand support and control, while simple reach adjustment allows fine-tuning for optimal comfort.

A 10% wider pad clearance reduces the risk of disc brake rotor rub, contributing to quieter and more efficient braking. The One-Way bleeding system simplifies maintenance, and button functions can be customized via the E-TUBE PROJECT app. The system runs on two CR1632 batteries with an estimated lifespan of 3.5–4 years.
