Topstone Carbon 1 Lefty AXS Gravel Bike - Black (2025)

Always Game
Our take on the ultimate all-round gravel bike. Go anywhere, bring everything and then keep on going.

Model Description
Built for riders who want speed, control, and a gravel ride that feels as good as it looks. KingPin and the updated Lefty Oliver fork work in perfect harmony, smoothing out chatter and ironing out the imperfections for more speed and less fatigue. Whether it’s a long grind or a fast-paced spin, they keep the ride controlled and composed, letting you push further without feeling it. The blended SRAM Rival AXS/GX Eagle AXS wireless group delivers crisp, effortless gear changes, while Reserve 40|44 wheels stay steady and surefooted across unpredictable terrain. This bike is where gravel meets greatness.
