Fly up climbs and accelerate faster
New carbon Adaptive layup technology shaves 70g per rim. 25mm wide rim weighs only 340g. Lighter hub design with 24 straight-pull spokes for improved stiffness.

Stiff, efficient power transfer and smooth ride quality
Special carbon rim layup for superior rim stiffness. Double-butted, two-cross spoke pattern for enhanced vertical compliance. Ultra-reliable ID360 dual ratchet freewheel for instant engagement helps you sprint out of corners faster.

Two rim width choices to suit your riding style and terrain
25mm hookless carbon rim option provides the lightest, most dynamic wheelset for XC racing.

At only 1340 grams, this is the wheel that performance-obsessed cross-country racers dream of. Developed with input from top pro racers seeking a competitive advantage at World Cups and the 2020 Tokyo Olympics, it features an ultralight full carbon 29” rim (340g) for fast acceleration and climbing without compromising stiffness and durability.

A specific carbon construction: Adaptive layup technology enabled us to handcraft these carbon rims with less material between the spokes. The spoke holes are reinforced with strategically positioned carbon layering in a process that minimizes weight without compromising stiffness and strength. A lighter rim means faster acceleration, more efficient climbing and a more responsive feel on the trail. Extensive field testing with our pro athletes determined that a 25mm inner width was ideal for a quick, precise ride quality and optimized tire grip on fast racetracks. For more technical trails, some preferred a 30mm width for added control, so we created two options. It’s your choice, and you can mix the two if you want.
The rim is laced with 24 straight-pull double butted spokes (same spoke length throughout), two-crossed for maximum power transfer and enhanced vertical compliance. The new lighter Infinity hub design optimizes lateral stiffness, and the spoke lacing maximizes power transfer. Our Instant Drive 360 freewheel with a double ratchet system provides fast engagement and high stiffness to help you accelerate out of corners faster.
