Feel the light

Light and lively, smooth yet snappy. Topstone's SmartForm C2 Alloy construction showcases our decades of expertise in aluminum craftsmanship.

Full Carbon Fork

A full carbon fork with a tapered steerer and 12mm thru-axles delivers a light, comfortable and precise-steering front end.

OutFront Steering Geometry

Keeps the steering light and agile, while positioning the wheel further in front of the rider for stability and confidence on rougher stuff. Plus it reduces the chance of toe overlap on smaller sizes.

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.

Removable Fender Bridge

Bolts on when you want fenders, disappears when you don't.
