Lightweight Efficiency and Stability
Built for fast riding and long climbs on uneven terrain, these tubeless GRX-level carbon wheels are lighter than past generations. A shallow 32 mm carbon rim accelerates quickly, stays composed in crosswinds, and supports modern tire widths up to 50 mm.

Direct, Responsive Power Transfer
These wheels use a DIRECT ENGAGEMENT freehub construction inspired by DURA-ACE, improving driving rigidity and responsiveness. The result is a connected, efficient feel when accelerating, climbing, or applying steady power over long distances.
Efficient and Stable Carbon Rim
The 32 mm carbon rim profile delivers quick acceleration and confident climbing while remaining stable in gusty conditions. Its low profile helps maintain control on exposed rough roads and during long efforts where efficiency and confidence matter most.
