1254g of intentional design.

Carbon Spokes | 2° Engagement | World Cup Refined

Developed for riders who understand that performance is rarely defined by one big improvement, but by dozens of small ones working together.

The Proven Race XC UD combines lightweight carbon rims, TaperLock UD carbon spokes, precision EZO bearings, and our fastest-engaging MTB hub system to create the lightest mountain bike wheelset we've ever produced.

Engineered in West Sussex and refined through UCI Cross-Country World Cup racing, every component was evaluated in pursuit of lower weight, reduced drag, and more direct power transfer. At 1254g, it feels quick to accelerate and immediate under power.

Tyre size: Optimised for 2.25" to 2.4" tyres; work well with 2.0" up to 2.6" tyres.

10/10 REVIEW

"A proper extra gear upgrade in terms of acceleration and pick and flick agility to whatever bike I fit them to and tangibly fast even when just rolling."

The Purpose.

<h1>Weight</h1><i>Engineered in West Sussex, UK and raced throughout the 2022 UCI XC World Cup season, Proven Carbon Race XC UD wheelsets weigh in at an unrivalled 1254g yet boast an impressive 30mm internal width for unbeatable strength and stability.</i>

The Purpose.

At the highest level of cross-country racing, small details matter.

A lighter wheel accelerates faster and reduced rotational weight helps preserve momentum. Faster engagement reduces wasted crank movement, while stiffer spokes respond more directly to rider input. None of these gains are dramatic on their own. Put them together and they change how a bike feels over the course of a race, from the first hard acceleration to the final climb.

The Proven Race XC UD was developed around that principle and refined through UCI Cross-Country World Cup racing.

Rather than chasing a single headline number, development focused on the details that influence speed over a full race distance. Carbon UD spokes reduce mass while increasing stiffness. A 90T ratchet system minimises wasted movement
at the pedals, while premium EZO bearings help preserve momentum over long race efforts.

Together, these details create a wheelset that feels quick to accelerate and eager to hold speed.

Key Features.

Hookless/Straight Sidewall Design

A lightweight 30mm-wide rim profile featuring a hookless straight-sidewall design and 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 and 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.

<h1>Bearings</h1><i>Precision EZO bearings with dual full contact seals protect against dirt, mud and water, ensuring long lasting durability, and zero drag, unbeatable performance.</i>

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.

Every HUNT wheelset undergoes extensive development and validation before reaching riders.

Using dedicated testing equipment and real-world athlete feedback, we evaluate wheel performance against demanding internal standards and benchmark products from across the industry. This process helps validate design decisions, identify opportunities for improvement, and ensure every wheelset meets the demands of elite-level XC racing.

At 1254g, every component plays an important role in how the wheelset performs. Lightweight carbon rims, TaperLock UD carbon spokes, precision EZO bearings, and our fastest-engaging MTB hub system work together to reduce weight, improve efficiency, and maximise responsiveness on the trail.

The carbon spoke system is one of the primary reasons this wheelset weighs just 1254g. At 2.7g per spoke and exhibiting 30% less extension under load than comparable steel spokes, the system helps maintain accurate wheel tracking and a direct ride feel without compromising long-term serviceability.

A full 3 years from purchase date warranty is offered to the original purchaser only on all Hunt bike wheels against material or workmanship defects, please click here to read full details.

Stated wheel weights: Our stated wheel weights reflect the wheelset only; without rim tape, tubeless valves or disc brake lock rings, as is industry standard. A 3% variance (lower or higher) in total system weight is normal for wheelset manufacturing.

All HUNT wheels models have to pass our harsh rolling-drum fatigue tests for rider weight limits, please see here for more details. Max system weight 135 kg (system weight – total weight of fully kitted up rider, bike and luggage). If the system is over 125 kg then an experienced bike mechanic should check the wheel regularly.
