PRODUCT DETAILS

Gravel cyclists live to be in the moment. It’s why we roll out of our driveway at dawn. Why we venture down lonely, unknown dirt roads. Why we take on routes and races with unpredictable outcomes. It's also why we demand the best from our gear; expecting precise, reliable, distraction-free performance in all conditions.

Shimano understands—and embraces—these lofty expectations, knowing that even the smallest hiccup can mean the difference between fun and frustration, failure and success. It’s this pursuit that defines the latest addition to Shimano’s growing family of GRX gravel-specific components.

Meet the new 12-speed Shimano GRX Di2 RX825 series, which includes dual control levers refined for comfort and control, a Shimano Shadow RD+ equipped rear derailleur for better chain management, and a gravel-optimized front derailleur for precise shifting.
