Sonder Alphas are our performance wheelset. It’s a light, versatile disc brake wheelset built for riding fast in all seasons. And while they’re made for speed, Alphas still easily take wide tyres and are tough enough to load up for multi-day trips on the road and trail.
21mm wide rims are perfectly suited for 28 – 50mm tyres, which means more traction through a broader contact patch and lower rolling resistance.
Alphas have been designed to be a durable, long-term part of your bike. They’ve been designed with long rides and endurance racing in mind – these would be a perfect choice for the Transcontinental Race. Sealed cartridge bearings make them easy to look after. And an alloy freehub body will take miles and miles of abuse.
Alphas give a beautifully fluid ride. Light rims mean they spin up to speed quickly while super-smooth bearings keeping you rolling and rolling. They’re the wheels we choose when we want to go far, fast. Road, gravel, loaded for multi-day racing, these wheels fly!
We lace, build and finish all our wheels by hand, with each one getting a full quality control inspection. Your wheels have a huge influence on the character of a bike. When you are able to look after the whole process, you can produce something truly special. By bringing wheel building to our our factory in the UK we increase quality and production efficiency and reduce the impact on the planet by not shipping boxes of wheels around the world.
