Built for the rigors of America’s longest mountain bike race, the Tour Divide-inspired Cutthroat C GRX 600 1x is one of the best bikepacking bikes for long rides through a variety of conditions and surfaces when speed is of the essence. Designed with drop-bar mountain bike geometry and a lightweight carbon frame featuring our Class 5™ VRS for comfortable compliance, Cutthroat is ready to put in big miles on any terrain. Ample cargo mounts let you distribute weight evenly around the bike for maximum maneuverability. Shimano’s GRX 600 1x drivetrain provides brilliant braking and shifting with the gear range for gravel flats and mountain passes alike. (ESTIMATED IN-STOCK DATE: DECEMBER 2022)
Cutthroat Fork
With trail-taming compliance and abrasion-resistant plates in high-wear areas, the Cutthroat Carbon fork is designed for the rigors of rides that cover multiple road surfaces in unpredictable conditions
Class 5 VRS
The Class 5™ Vibration Reduction System revolves around seatstays with a tall, thin, vertically-oriented profile that promotes vertical compliance by allowing the seatstays to "flex" outwards on impacts. Horizontally-oriented chainstays work to resist torque and maintain a laterally stiff rear end. The lack of seatstay and chainstay bridges allows the full length of the stays to contribute to flexibility. A rear thru-axle delivers precise tracking while allowing the seatstays to provide incredible compliance.
