Already a recognized winner, our sub-1400g Solix M UL300 is designed for optimal speed and efficiency, whether on the XC race course or in any go-fast scenario requiring our premier UL-series mountain bike wheelset. The UL300 rim belongs to our premium carbon collection, our top-tier, exclusive line of carbon rims. Each rim is handmade in Canada and comes with a lifetime warranty.

Designed with a lay-up schedule that values ride quality and weight reduction, the 30mm rim inner width keeps tires up to 2.5” secure, plus the hookless design reduces the effects of impacts on both the rim and helps keep tires free of pinch flats. On the trail, the Solix M UL300 springs into action through the Solix drive system, our lowest drag and most XC-optimized hub and spoke system chassis to date.



5 Pawl Solix Freehub Body

Our patent-protected freehub technology offers unrivaled .59° engagement for our Solix family of wheels.

24h 2:1 Solix M

Built for speed and efficiency, our Solix M hub and spoke chassis features 24 aluminum spokes for exceptional stiffness to weight.

Premium Carbon Rim

A collaboration with We Are One, our exclusive premium carbon range of rims employ hookless construction for maximum impact resistance and carry a limited lifetime warranty.

Direct Thread - Straight Pull

Straight pull, integrated nipple, one-piece aluminum spokes that thread directly into the hubshell resulting in a solid, flex-free junction. No special tools or service procedures required.

Lifetime Warranty

Complete system wheel warranty coverage against defects on your carbon wheelset for as long as you own them.
