Roval Traverse SL II Hydra2 29 Mountain Bike Front Wheel 28H - Satin Carbon

Season:2025

Brand:Specialized

Code:30125-8101

Conquer aggressive mountain riding with the Roval Traverse SL II Hydra2 29", a premium carbon trail wheel.

The Roval Traverse SL II Hydra2 29” Front Wheel is engineered for riders who demand lightweight performance, exceptional durability, and precision handling on challenging trails. Featuring a 28-spoke count, a 30mm internal width, and a Satin Carbon/Satin Black finish, this wheel is built to tackle both aggressive climbs and technical descents with confidence.

Built around the Industry Nine Hydra2 hub with an ultra-fast 0.41° engagement, the Traverse SL II delivers instant power transfer and seamless traction. Whether you're flowing through singletrack or charging down rocky descents, this wheel gives you the speed, control, and compliance you need to ride faster and harder.

Trail-Tuned Strength and Compliance

The Traverse SL II front rim features a newly engineered carbon layup, increasing strength by 15% over its predecessor. The shallow rim profile delivers 21% more vertical compliance, smoothing out trail chatter and impacts for better control and rider comfort.

Engineered for Real-World Trail Riding

Unlike traditional symmetrical wheels, the Traverse SL II uses front- and rear-specific rim designs to meet the distinct demands of each wheel’s load profile. Up front, it’s tuned for steering precision and vibration absorption, giving you more traction and confidence on every descent.

FlatStop™ Technology – Ultimate Pinch Flat Protection

Say goodbye to snake bites. The Traverse SL II is equipped with FlatStop™ bead technology, a 5mm wide rim bead that requires 85% more force to pinch flat than standard rims. This patented design provides best-in-class protection against impact flats, even at lower pressures.

Perfect Pairing with Specialized Tyres

Maximise performance by pairing the Traverse SL II with Specialized Butcher or Eliminator trail tyres. These tyres are co-developed with Roval to perfectly complement the rim’s profile and compliance, delivering unmatched grip, stability, and flat-resistance when it matters most.
