Shimano GRX RX800 Gravel Groupset Description:

For gravel racers, there is nothing quite like the reliability of mechanical shifting paired with powerful hydraulic disc brakes. Taking hints from Shimano's road bike line, GRX features a 327% gear range that's perfect for anything from sprints to climbs. Redesigned shift levers provide a better interface with flared handlebars, making this groupset the perfect fit for many gravel builds.

Note: GRX Crankset sold separately
