Alphas are our performance 27.5" wheelset for big hits and big tyres. Whether you're riding down Top Chief at Fort William or riding the black routes at Bike Park Wales, Alphas will consistently spin up to speed and keep rolling to help you ride with fluid precision over the trails.

Our design team’s expertise along with the factories we use mean that we can accelerate trickle-down technology to this price point.

Alpha hubs: wider, stiffer, tougher, faster

Alpha’s boost hub is wider than a standard hub; extra width between the flanges promotes a shallower spoke bracing angle to create a stronger, stiffer wheel. A wider hub also means a shorter chainstay, more mud clearance, and better tyre clearance. To make them faster we’ve used a 6 pawl freehub, which gives 120 points of engagement for immediate response when you turn the pedals (most hubs only have 60, which means you have to turn the pedals further before engaging the freehub). Oh, and the hubs sound amazing! Finally, sealed cartridge bearings just keep rolling and rolling.

Wider rims mean tyres work better

35mm lightweight aluminium rims make this wheelset ideal for rock gardens an
