An amazingly capable, versatile gravel road bike. Built for chasing horizons, exploring routes less travelled or accelerating your commute.
Where it thrives: Gravel roads, out in the elements
What it’s built for: Traction, handling, 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 tires lets you push further into the rough stuff, and enjoy more grip and comfort on every ride.
- 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.
