This high-performance carbon all-rounder features a new, taller 45mm rim shape that minimizes drag. It also has a wider external diameter (28mm) that optimizes the aero performance of 25mm tires. Add in our UST technology, the most user-friendly tubeless road setup on the market and a disc-brake specific build, and you have the most advanced, high-performance wheel for speed, puncture resistance, and smooth-riding comfort on the road. This updated wheel-tire system is now engineered with fewer spokes than the previous version (20 compared to 24) and those spokes feature a patented elliptical shape. As a result, overall weight has been reduced 70g with no compromises to stiffness or strength. Made specifically for disc brakes, the front spokes are crossed on each side of the hub to transfer the braking load to the ground without any flexing or wheel wobbling.
The wheel-tire system comes with Yksion Pro UST tires that provide a simple, hassle-free tubeless road setup with high rolling efficiency and maximum grip in all weather.
Taller, wider rim profile improves aero efficiency
- 45mm NACA rim profile, 28mm wide, optimized for 25mm tires, only possible when removing the constraint of the brake track
- 20 elliptical spokes (patented)
- New slick 12mm front hub
Roll faster and smoother with a reduced risk of punctures
- No tube, no friction: less rolling resistance and higher speeds
- UST Road Tubeless lets you ride with lower tire pressure for a smoother ride quality.
- Perfect union between tire and wheel, so installation, removal, and maintenance are easy
Disc-brake technology gives added braking control
- 20 spokes front and 24 rear for optimized brake torque distribution
- Full axle and freewheel compatibility
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
