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.



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 Alloy Rim

High quality aluminum alloy with weatherproof sublimated graphics, tubeless friendly bead shelf, and a proprietary profile to keep dents at bay.

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.

2-Year Warranty

Warranty coverage against defects on your Industry Nine wheelset or Classic hubset.
