Roval Traverse SL II Hydra 6B front wheel 2025

Smoother is Faster

The Traverse SL II delivers lightweight performance that’s perfect for riders who want to ascend fast and descend with control. It features four key innovations. First, optimized front and rear rim layups boost strength by 15% and 25%, respectively. Second, shallow rim geometry increases vertical compliance by 21% for better impact absorption. Third, the engineered “ankling” enhances traction, stability, and control. Finally, the FlatStop rim bead requires 85% more force to pinch flat.

Stronger Than Ever
Front and rear-specific rims ride smoother, yet are 15% stronger upfront and 25% in the rear.

21% More Compliant
21% more vertical compliance absorbs bumps smoothly, keeping you in control.

85% More Force to Flat
FlatStop technology requires 85% more force to pinch flat, virtually eliminating "snake bites.”

Roval ThreadBed Valve
Eliminates compression nuts, air loss from rim flex, makes tire set-up easier, and reduces sealant clogs.

0.41° of Engagement
The i9 Hydra2 hub has 145 teeth and 0.41° of engagement for immediate power transfer.
