Performance Design
XSL is tuned for cross-country speed with real trail durability. The low 25mm profile keeps weight down for quick acceleration and climbing efficiency, while the 25mm internal width improves tyre support for stable cornering and predictable handling.
The carbon structure is designed to deliver stiffness under power without feeling harsh. You get direct response on climbs, controlled tracking through rough sections, and reliable traction over long rides.
- Fast climbing and quick acceleration
- Cornering stability and tyre support
- Efficient tracking on technical XC trails
- Lightweight feel without sacrificing trail strength
Intended Use
XSL is built for riders who want a lightweight 29″ wheelset for XC and trail riding — where speed, climbing efficiency, and confident handling matter equally.
It is ideal for mixed terrain: climbs, rolling singletrack, and technical descents, offering a balanced platform that feels fast without feeling fragile.
- Cross-country and marathon riding
- Trail riding with technical climbs
- Riders prioritising low weight and responsive handling
- All-round MTB use with XC performance bias
