GRX ST-RX610 12-Speed Shift/Brake Lever with BR-RX410 Caliper - Right/Rear, Black

Shimano GRX ST-RX610 12-Speed Shift/Brake Lever with BR-RX410 Caliper delivers precise control and confident braking for gravel, adventure, and mixed-terrain riding. Built around Shimano’s proven GRX design, this right-side lever and caliper combination balances smooth mechanical shifting with powerful hydraulic braking to handle rough roads and unpredictable conditions.

A textured hood and anti-slip brake lever surface provide secure grip and consistent control, even when riding over washboard terrain or in wet weather. The BR-RX410 flat mount caliper offers excellent modulation and a quicker initial bite, giving riders more confidence when descending or tackling technical sections. Despite its compact and lightweight design, the system runs quietly and is easy to maintain—ideal for riders who spend more time exploring than wrenching.
