Gravel drivetrains hit a fork in the road a few years back—stick with adapted road parts, or commit to something built for the actual conditions. Shimano's answer was GRX, and the RX810 tier sits at the top of the mechanical lineup with Ultegra-grade internals reshaped for dirt. This kit bundles the shifting and braking half of a 2x11 build with an 11-34T cassette and CN-HG701 chain, so you can pair it with the crankset, bottom bracket, and rotors of your choice without hunting individual SKUs.

The ST-RX810 dual control levers are where the gravel-specific thinking shows up first. The brake lever pivot axis sits 18mm higher than standard road levers , which shortens the throw to initial pad contact and gives you more usable modulation once the pads are engaged. The hood shape has a more pronounced upward slope than a road lever, so your hands stay planted when you're bracing over washboard instead of sliding forward into the drops. Anti-slip texture on the hood rubber and brake blade holds grip in wet or dusty conditions, and tool-adjustable reach lets you dial in lever distance for smaller hands or gloved riding.

Out back, the RD-RX810 rear derailleur uses Shimano's Shadow RD+ geometry to tuck the cage close to the frame for ground clearance, and the clutch tensioner keeps chain slap and drops in check on rough descents. The clutch is tuned for gravel conditions and includes an on/off switch for easier wheel removal. The medium cage handles road-style cassettes up to 34 teeth—this is a road-oriented rear mech, not a mountain unit, so mixing in a wider MTB cassette isn't in the plan.... Read More
