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 _

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 didn’t 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.

KEY FEATURES_

Hookless/Straight Sidewall Design

30mm-wide external rim profile, featuring a hookless/straight-sidewall and ETRTO-compliant tubeless rim, designed for MTB tubeless tyre compatibility.

UD Carbon Spokes

TaperLock UD carbon spokes offer up to a 30% less extension under load against steel equivalents. Only 2.7g per spoke and yet can handle tightening forces of ~405kgf per spoke. Fully serviceable and replaceable.

S_RapidEngage Hub


Crafted to remove unnecessary weight without compromising durability or performance. S_RapidEngage system features a 3x2 system with double-tooth pawls engaging with a larger 90t drive ring to offer incredible 2-degree engagement angle for instant power transfer from the pedal to the track.

<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

Ultra-low friction, precision-engineered EZO bearings minimize energy loss and maximize speed through their advanced design that allows for lightning-fast rolling.

3D Modelled Hub

A large drive-side hub flange increases the space for the new 90t ratchet ring and allows built a wheel with equal spoke tension.

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.

Tyres Info
HUNT recommends a 2.2"-2.4" tyre for best performance, tyre widths between 1.9" and 2.8" are also safe to use.   Note: best performance is usually gained by using tyre pressures lower than the maximum, you can see our blog post about this, read here.  Tubeless-ready for lower weight and rolling resistance.  Only use tyres marked as compatible with hookless (TSS) rims.  You must not exceed the maximum tyre pressure limits set out in the table below or the maximum limit set by your tyre manufacturer if this is lower.

WARRANTY_

These wheels come with H_CARE (Free Lifetime Crash Replacement) for the first owners when used with single crown forks. Read all about it here.

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.
