GRX Dropper Post Lever w/ RX810 Brake Caliper
Back in the day, preparing for gravel racing and adventure riding meant having to decide between pure road components or mountain bike components. There can be drawbacks to both. The GRX ST-RX810 Dropper Post Lever allows you to lower your center of gravity, when you're descending those long bumpy fire-roads in the drops, improving confidence and control. There's no need to change hand position mid-ride to initiate your dropper post. The ST-RX810 Dropper Post optimizes space in your cockpit for a more sleek, minimal look while giving you maximum control, removing the need to move your hands out of your drops.
Please note: this lever is only compatible with Shimano GRX 1x drivetrains. Dropper actuation takes the place of the left shifter which prevents 2x compatibility. Additionally, the shift cable head must be positioned at the lever. This means it only works with dropper posts that can clamp to the cable itself without relying on having the cable head at the post.
RX810 Brake Caliper
The Shimano BR RX810 Hydraulic Disc Brake calipers offer a sleek design that integrates seamlessly to your bike's profile. The flat mount design offers aerodynamic advantages due to the closer fit between the frame and the caliper. The low-profile BR-RX810 has an anti-mud specification, excellent heat dissipation, and convenient tool access, to provide superior performance and greater control for mixed-terrain riding.
