Sonder Alphas are our performance wheelset. And while they’re built for performance, Alphas still easily take wide tyres and are tough enough to load up for multi-day trips on the road and trail. Light rims mean they spin up to speed quickly while super-smooth bearings keeping you rolling. They’re the wheels we choose when we want to go far, fast. Road, gravel, loaded for multi-day racing, these wheels fly!
- Disc brake specific and tubeless-ready design for 28-50mm tyres
- 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’ve used a 6-pawl freehub for instant acceleration and maximum pedalling efficiency. This gives 120 points of contact - just 3° of rotation between each click. With faster engagement, the wheels respond the minute you put the hammer down and save wasted watts.
Made from a premium KLM41 (6061) alloy, we’ve been able to maximise rim strength and stiffness for a lower weight. They’re also welded and pre-taped for a tubeless-ready set up to save more weight and reduce rolling resistance.
21mm wide rims are perfectly suited for 28-50mm tyres, which means better traction, more comfort, greater control and the ability to run a lower tyre pressure. We’ve also used Sapim Laser double butted spokes to reduce weight and increase stiffness.
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.
