Sonder Alpha 27.5 is our performance wheelset for aggressive riding. They come alive on tight, twisty terrain and accelerate fast to make root-riddled trails easy to manoeuvre. They’re at home in your local trail centre, ready to play on the red runs.

  • Disc brake specific and tubeless-ready design up to 2.8” tyres
  • 30mm internal width, Sapim double butted spokes
  • 120-point engagement for quick acceleration and pedalling efficiency
  • 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. And a 17mm alloy axle make the hubs bombproof.

    60-Day Wheel Ride Guarantee - love them or we'll give you your money back

    If you don’t bond with your wheels, you can send them back for a no-quibble refund within 60 days. We’ll even cover the cost of returns postage for UK orders.

    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.
