Explore further. Ride freer.
An amazingly capable, versatile gravel road bike. Built for chasing horizons, exploring routes less travelled or accelerating your commute.

Two rings, endless possibilities. This Topstone is built to tackle the toughest gravel rides with Shimano GRX 400 2x10-speed shifting and a SmartForm C2 Alloy frame. With ample tire clearance and mounts for racks and gear, it’s engineered to meet the demands of adventurous riders and unpredictable routes.

What it's for
Gravel-riding, exploring, bikepacking, performance commuting

Highlights

  • Lightweight SmartForm C2 Alloy frame w/ full carbon fork

  • Reliably precise shifting from the Shimano GRX 400, wide-range, 2x10-speed gravel drivetrain

  • Powerful, controllable braking from Shimano’s GRX400 hydraulic disc brakes

  • Selle Royal SRX Open saddle balances supportive padding and a pressure-relieving central channel for performance comfort



Features

  • 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 tyres 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.

  • 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. The full 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.
