Description GRX ST-RX815 Di2 Individual Lever
No longer do you need to piece together mountain and road bike components to get exactly what you want for your off-road drop bar bike. Playing bike surgeon with the random parts you've gathered can be fun, but efficiency and the reliability that everything will -- just work -- is much more satisfying.
Rough road ready.
Following the launch of Shimano's GRX system, the option to elevate that group beyond your usual cables and into the electronic level is here. On the inside, the Ultegra Di2 is the same, but the outside is a brand new beast. Featuring a much more drastic slope, the new gripping traction will help keep you secure in the cockpit as you fly down gravel roads, without letting an unexpected bump throw you off your line. Braking on rough terrain is all about precise calculations and the new re-positioned lever makes it easier to access your brakes, whether in the drops or on the hoods.
Tuned for off-road.
Distinguishable clicks between upshifts and downshifts are effortlessly reachable from both riding positions, allowing you to focus on the terrain ahead and giving you peace of mind.
A raised hood head prevents hand misalignment and slippage, while a recessed finger notch prevents upward slipping
Anti-slip texture and brake lever coating
Higher brake lever axis and curved lever allow for higher braking efficiency to reduce fatigue on long rides
