Fast as a road racer, rugged as a mountain bike, and priced beyond compare—the G.1 is one bike to rule them all. With flat mount disc brakes, through axles, and drop seat stays for the plushest ride, this bike, crafted by some of the world’s leading carbon fiber technicians, defines the modern, all-road machine. It combines generous tire clearance and a stable-but-not-too-tall front end for a quick but smooth ride feel, even on the most bracing terrain. And because our builders have been crafting some of the finest carbon frames for a generation, you can trust that our bikes will last.
Smart money buys the G.1 105. For little more than the base price of a bare frame, you get the same highest-grade carbon build as our top-end model mated to the unflinching performance of a Shimano 105 drivetrain, disc brakes, Zipp cockpit, and HED tubeless-ready wheels. The only thing more satisfying than the superb ride is how little it costs.
