All New SOLIX Mountain Collection

Perhaps no other aluminum performance XC wheelset can keep up with Solix M UL250 in between the tape. In terms of weight, engagement, and ride quality, Solix M UL250 leaves competition in the dust. Tipping the scales at an attractive 1425g, the UL250 leaves nothing to be desired when the course climbs, but rest assured the tubeless-ready 25mm inner width rim is eager to hit the huck lines when the track points back down. We’re confident no hubset on the startline boasts the depth of Solix’s performance-driven feature set.

Attack from the start with 605 points of terrain-taming engagement at your command and our all-new full bearing and freehub seal configuration ensures you’ll have more mud on your face than in your hubs. You'll quickly forget you're on an alloy-rimmed wheelset as the Solix M hub and spoke chassis navigates rough sections with a precision unmatched by any steel-spoked wheelset in its class.
