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.

Room For 45 mm Tires

Whether you need mud-shedding clearance for the 'cross course or some serious tread for a rough and tumble gravel track, there's room for 45mm tires - if only the UCI would get on board.
