PRODUCT HIGHLIGHTS

Full Carbon Fork-Light, comfortable and precise. An all-new carbon fork features three mount bosses on each leg for maximizing cargo capacity, plus an easy mounting point for fenders - letting you ride any adventure in any condition.

OutFront Steering Geometry - Confident stability meets nimble agility. An extra long fork offset paired with a slack head angle keeps the steering light and lively, yet delivers unreal confidence at speed and in the rough stuff.

Dropper Ready - Built to accept an internally-routed 27.2 dropper seatpost, which shouldn’t really be a surprise on a bike that's this off-road capable.

Load Up. Roll Out - With plentiful gear and water bottle mounts on the frame and fork, Topstone is ready to load up and go long.
