Cutthroat C GRX 810 2x is an immensely capable carbon bikepacking bike, designed and built to be a tour de force on the Tour Divide. Cutthroat’s lightweight carbon frame with Class 5™ VRS offers a finely tuned blend of stiffness for pedaling efficiency and compliance for all-day comfort. Cutthroat’s drop-bar mountain bike geometry is stable when picking your way down steep, loose descents but aggressive enough for enduring a full day of headwinds.
