Shimano GRX RX800 Gravel Groupset (Black)

Gravel riders want gear they can depend on. The Shimano GRX RX800 Groupset is a workhorse – designed to take on the most rugged rides and come out ready for more. Sharing some components with Shimano's Deore XT mountain bike group, GRX features a clutch derailleur, wide-range cassette, and 1x gearing. While many riders are opting for high-tech electronic components, the RX800-series embraces the simplicity and reliability of mechanical shifting paired with the power of hydraulic disc brakes.

• 1 x 12 GRX "Unstoppable" groupset provides ample gearing for all-day adventure
• Shifter hoods optimized for flared handlebars and rugged terrain
• Servo Wave brakes offer better modulation and 10% wider pad clearance
• Clutch derailleur keeps the chain in place over rough terrain
• 1x setup simplifies shifting for offroad riding
