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
Built to last: fully serviceable and repairable with no specialist tools required

Our alpha hubs are built to last, a durable 4 pawl setup with a 30 tooth ratchet ring gives 12 degrees between each engagement. We’ve used a 4-pawl freehub for instant acceleration and maximum pedalling efficiency. 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 perfe
