Amazingly capable

Straightforward, reliable and a whole hell of a lotta fun, the Topstone Alloy is a gravel bike crafted for those with a taste for adventure – and value. Roll light and free, or load it up for a long haul, Topstone’s comfortable ride, confident handling and up-for-anything capability make it the perfect partner on any road, anywhere.

Wide Ranging Capabilities

Clearance for big 45mm tires lets you push further into the rough stuff, and enjoy more grip and comfort on every ride.

Easy to Live With. Easy to Love.

Everything on the Topstone is designed for simplicity, ease of use and compatibility. Whether you're setting out on a big ride or taking the long way to work - less down time, more ride time.

Load Up. Roll Out.

With plentiful gear and waterbottle mounts on the frame and fork, Topstone is ready to load up and go long.

Features

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.

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.

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.
