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.

GRX ST-RX815 Di2, eye-catching for a gravel bike upgrade, These are great fit in the hand. Shimano put a little off-road feel into these shifters, allows me to hold tight as the hoods are sleek; I feel I have a good firm grasp on the bike, and it wont get away from me on a bumpy decent, tested on Forest park. The electric shifting is a real bike up-grade, making the shifting experience quick and efficient.
As I enjoy both a cable system bike and this electrical shifting system. Shimano is a reliable, well build system.
Di2 is not necessary nor for everyone; the gears shift like a 'mouse click', and I did it with my pinky (laughs).
It doesn't make cycling easier, you just go faster (shifting gears)
Using this on a gravel bike but would hesitate to use on a road bike either. The ergonomics of the hoods and pivot point of the brake lever is superior to the road Di2 equivalents.
