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.
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.
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 you’re 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. We’ve 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.
