Ready for Every Adventure
Our interpretation of the ultimate all-round gravel bike. Go anywhere, carry everything – bikepacking at its best.
Model description
The Topstone Carbon 3 GRX 2X is a versatile gravel bike built for riders who love long adventures as much as fast training rides. Its lightweight carbon frame with KingPin rear suspension delivers noticeably more comfort and traction on rough terrain, while the reliable Shimano GRX 2x12 drivetrain provides a wide gear range for steep climbs and fast sections alike.
With generous tire clearance, practical mounting points and the integrated StashPort storage compartment, the Topstone becomes a true partner for long-distance gravel rides and bikepacking adventures. Robust WTB wheels combined with 42 mm Resolute gravel tires provide excellent grip and control across mixed terrain – from loose gravel roads to fast asphalt stretches.
