Climbs as hard as the descents? Looking for the perfect balance of weight, width, and stiffness? The Ultralite235 is the wheelset for your ride. Sporting our revised, second generation UL rim, the Ultralite235 increases rim width to 23.5mm internal, places more material in places where it matters most, and optimizes retention and footprint on the trail.  

Class leading strength, stiffness, and weight will help any XC/Marathon or Adventure racer find the top step of the podium. 


The 24 hole Torch hub and spoke platform cut an incredible amount of weight without sacrificing strength or performance. The tapered spokes are thicker without being heavy, the hubshell is lighter without losing it's strength, and the drive ring is thinner while maintaining it's quick engagement. 


By utilizing Teflon shields and o-rings that snap onto the end caps, our hubs have two seals on each bearing to help keep grit out, significantly increasing the bearing life. Which helps you stay out of bike shops and onto the trails - where you belong.


We made the world's most convertible hub over 8 years ago, and the new Torch will continue to keep you safe from new standards by easily swapping end caps to adapt to new standards. QR, 15mm, 12x142, 9mm thru, Boost 15x110 (32h only) -we've got you covered. 


 Through clever bearing arrangement in the freehub, we have managed to keep the 3° engagement, yet eliminate the drag. Thicker spokes stiffen up the ride without making it harsh, and an oversized axle efficiently delivers the power.


Like all of our System Wheels, you can customize your hubs and spoke colors in any combination for an additional fee. We offer 11 custom anodized colors: Orange, Purple, Turquoise, Lime, Gold, Green, Blue, Red, Pink, Silver and Black. Visit our AnoLab Custom Wheel Designer to customize your i9s.
