Description

GRX ST-RX815 Di2 Shifter & Disc Brake Caliper

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 long-time staple of mountain biking, and finally reaching gravel riding, Shimano introduces ServoWave to its BR-RX810 flat-mount calipers. The reliable stopping power of ServoWave is coupled with the cooling technology of IceTech brake pads, improving upon standard Ultegra modulation.

When the riding gets rough, Shimano's GRX ST-RX81 has you covered with smooth, precise shifting and increased control on all the roads and trails that await.


Features:

  • Shimano brings Di2 to the gravel scene for precise, electronic shifts
  • Redesigned hoods feature steep slope to keep your hands secure
  • Off-road tuned anti-slip texture on hoods help you stay in place when it's rough
  • Higher brake lever axis and curved lever allow for higher braking efficiency to reduce fatigue on long rides
  • ServoWave technology on the flat-mount calipers improves modulation
  • Big shift buttons with positive clicks let you focus on riding, not shifting
  • E-Tube technology allows you to fully customize your shifting
  • Built to be run as a 2x11 group with GRX Di2 derailleurs
  • Caliper features Shimano IceTech technology for excellent heat dissipation
