Sonder Alpha 29 are our performance disc brake wheelset built for mountain bikes. They come alive on rough terrain, absorbing everything in their path, whether you’re riding down Top Chief at Fort William or your local trails. Sonder Alphas spin up quickly and keep rolling with precision over rough terrain.

• Disc brake specific and tubeless-ready design up to 2.8 tyres
• 30mm internal width, Sapim double butted spokes

• Built to last: fully serviceable and repairable with no specialist tools required

We use the modern boost standard for all our mountain bike wheels. This gives a wider hub to create a stronger, stiffer wheel with more clearance for mud and tyres. Sealed cartridge bearings keep you rolling longer and are more durable and simpler to service.

Our alpha hubs are built to last, a durable 4 pawl setup with a 30 tooth ratchet ring gives 12 degrees between each engagement. Weve used a 4-pawl freehub for instant acceleration and maximum pedalling efficiency. the wheels respond the minute you put the hammer down and save wasted watts.

Premium KLM41 (6061) alloy rims make this wheelset ideal for rock gardens and tough, technical terrain. 30mm internal width means you can run up to 2.8″ tyres for maximum traction and confidence.

Sapim Double-butted spokes have been chosen to keep the wheels super-strong, whether youre landing big drops or loading your bike with luggage.

Made in Britain

We lace, build and finish all our wheels in our Nottingham factory, with each one getting a full quality control inspection. Weve brought the build process in house from overseas to enable us to produce something truly special. We can over see the whole construction of our wheels and keep quality consistent, production efficient and reduce the impact on the planet by not shipping boxes of wheels around the world.
