More details

Our lightest and most advanced carbon race XC wheelset weighing just 1254g. Tuned carbon rims, 30mm internal rim diameter, ultra-lightweight but strong carbon UD spokes, and boasting our S_Radpidengage 2-degree engagement freehub.

The Purpose _

Beginning with the rims, Proven Carbon Race XC UD follow the principles of the rest of the Proven family, offering tuned compliance and stability with a modern 30mm internal width, but with the goal of making a competitive XC race wheel, low weight. Using carbon UD spokes the Proven Carbon Race XC UD is our lightest mountain bike wheelset.

Design changes like a reduction to a 22mm rim height and 36mm external rim width naturally reduce materials and weight, but our engineers didnt stop here. Through the testing and study of carbon processes, resin choices and construction methods, we have been able to shave off every unnecessary gram while reinforcing key structural areas. The result is a front rim weight of 348g and a rear of 369g.

The search for speed didn't just stop at low weight. Our engineers also heavily invested in increasing efficiency by utilising super smooth EZO bearings throughout and updating our ratchet system to the latest S_RapidEngage system featuring a 3x2 pawl design and increased 90T ratchet for an incredible 2-degree engagement angle for instant power transfer from the pedal to the trail.

Note

Please note these are refurbished wheels and some specifications may vary. These wheels have been inspected by our expert wheel builders and they come with our 3 year warranty as found on our new wheel products.

KEY FEATURES _

Hookless/Straight Sidewall Design

A lightweight 30mm-wide rim profile
Hookless straight-sidewall design & ETRTO-compliant tubeless dimensions.
Developed to provide excellent tire support, predictable handling, and reliable tubeless compatibility for XC racing.

UD Carbon Spokes

TaperLock UD carbon spokes reduce rotational weight while delivering a direct & accurate ride feel.
At just 2.7g per spoke, they offer 30% less extension under load than comparable steel spokes and remain fully replaceable for long-term serviceability.

S_RapidEngage Hub

The S_RapidEngage hub system uses a 90T ratchet ring to deliver near-instant 2° engagement. Whether accelerating out of corners or ratcheting through technical climbs, the hub responds immediately when you get back on the pedals.

Bearings

Premium EZO bearings are selected for their low rolling resistance, durability, and precision manufacturing standards. Full-contact seals help protect against contamination while maintaining smooth operation in demanding riding conditions.

Balanced Hub Design

A large drive-side hub flange creates the space required for the oversized 90T ratchet ring while contributing to balanced spoke tensions throughout the wheel build.
The result is a strong, efficient, and fully serviceable hub platform designed for XC racing.

TECHNOLOGY _

In-house testing is something we take very seriously here at HUNT and having 24/7 access to our new engineering facility and custom impact test rig ensures we are 100% confident that each new HUNT wheelset meets our high standards. The graph shows the impact test results of Proven Carbon Race XC and leading competitors. The graph shows the impact energy (J) recorded at the first sign of failure.

To ensure the same level of responsiveness and predictability from fewer spokes while ensuring a maximum weight advantage, we have taken a lesson from our range of road wheels and use carbon UD spokes. These incredibly strong carbon fibre spokes weigh just 2.7g each but deliver an astounding 30% increase in 30% less extension under load compared to steel alternatives, making it possible to reduce our spoke count without compromising our ability to hold a line and remain precise and comfortable in challenging race environments.
