Air Forming

The fork and frame tubes on the Roughneck are made by SPF Air Forming. SPF is carried out at high air temperatures, where the tube structure is in its most 'plastic' and formable state. This allows more complicated shapes to be produced that cannot be made using traditional forming techniques. For the fork, air forming produced a one-piece lower leg and crown eliminating the need for welding at this common joint. The result: more optimized shapes and less weight.

Frame Clearances

The 12x197mm rear hub and 100mm wide bottom bracket shell combination provide clearance for a double chain ring set-up and up to a 4.5" rear tire. The Roughneck's air formed fork and 15x150mm front hub provide clearance for up to a 5" front tire. 

Why Thru Axles?

Securing the rear wheel to the frame by threading a 12mm axle into the rear drop-outs is not only safer, it's stiffer. The rear wheel tracks directly in line with the frame, for more precise handling, so you can go faster with more confidence. The increase in stiffness of a 15mm fork axle improves steering and handling significantly. The hub drop outs provide a self centering feature for the wheel for fast, easy installation.

Ready to Load

The Roughneck's frame features rear rack eyelets and enough cargo/water cage mounts for the option to load up all the gear you may possibly need out there. Internal cable housing allows for the uninterrupted shifting performance when using a frame bag. 


Benefits of a tubless set-up are reduced rotating weight and the ability to use lower inflation pressures for a greater traction without the risk of pinch flats.

Tapered Head Tube and Fork Steerer

Riding with control requires steering precision, which starts with the front of the bike. Stiffening this area results in less wheel defelction, more wheel control. A tapered 1 1/8" to 1 1/2" head tube and steerer serves up a significant increase in rough terrain tracking and stability without much of a weight penalty compared to standard 1 1/8" systems since the steer tube wall thickness can be reduced. Adding a 15mm QR thru-axle hub/fork interface takes steering precision over the top.
