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.

20mm wide rims are perfectly suited for 28 – 50mm tyres, which means more traction through a broader contact patch and lower rolling resistance. Alphas are machine built for precision on Sonder’s sealed 6 pawls hubs, which have 120 engagement points in the freehub to give you immediate engagement when you start pedalling (most hubs only have 60, which means you have to turn the pedals further before engaging the freehub). Oh, and the hubs sound amazing!

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!
