Vezi acum FRANA DISC SHIMANO GRX ST-RX610/BR-RX400 Spate / J-Kit / Placute resin radiator

A central concern of Gravel riders is a reliable braking system with sufficient power reserves, the new Shimano GRX 2-speed ST-RX610 STI with BR-RX400 Flat-Mount caliper for hydraulic disc brake is characterized by excellent deceleration performance to maintain control on steep, demanding or even surprising descents.
Finally, for more budget conscious consumers and to allow a wider price range on complete gravel bikes, Shimano has updated its 600-series cranks and shift levers for 1×12 and 2×12 setups that utilize trickle-down technology from the original 800 series GRX component line.

From the beginning, riders have counted on Shimano GRX for the smoothest shifting, most reliable braking, and ultimate gravel comfort with thoughtful ergonomic designs and gravel-centric gearing. Now, with the updated 12-speed mechanical GRX lineup, you get more. More options, more gears, more opportunities to get out and ride exactly the way you want to ride. No matter which Shimano GRX option you choose, you’ll have the right gear—and gearing—for your next off-road adventure.
