Shimano GRX ST-RX815 Left Di2 Shifter & Front Disc Brake Caliper
The shift buttons are designed for easy reach from the hoods as well as in the drops, and offer a distinguishable click between upshifts and downshifts for a little extra peace of mind when you're 160-miles deep in a gravel race, and each deliberate move matters. Like its Ultegra road counterpart, the feel of shifting is much like clicking a mouse, requiring just 2-millimeters of movement on your end, so you don't have to put nearly as much focus into shifts, enabling you to pay more attention to the terrain ahead. On the back end of things, Shimano utilizes its BR-RX810 flat-mount calipers for reliable stopping power of ServoWave, and cooling properties of IceTech brake pads. The calipers operate with similar modulation to standard Ultegra, but ServoWave adds in improved feel right out of the gates, as the pads move together more quickly at first, before slowing for better control as you brake. This technology has been popular on the mountain bike side of things for some time, and now is trickling into gravel, where we get to enjoy the benefits of our off-road counterparts.
