FIRST LOOK: HUNT 25 & 40 CARBON GRAVEL RACE DISC WHEELS

New gravel hoops for racing and more.

Press Release

The 25 CGR is a lightweight race-focused hookless gravel wheelset built to offer versatility for the harshest and steepest days. The Hunt 40 CGR is a lightweight race-focused hookless gravel wheelset built to offer speed on the very fastest courses. The wide, asymmetric rim profile on the 25 Carbon Gravel Race Disc offers compliance and impact resistance for rough, technical courses. The 40 Carbon Gravel Race Disc offers lateral responsiveness and an aerodynamic profile. There is a 25mm (40 CGR) /26mm (25 CGR) internal hookless rim, designed for 28mm+/35mm+ tubeless tires. All-new Sprint SL hub shell is made from 6066 aluminum alloy, offering a greater strength-to-weight ratio than other alloys. High-grade, precision sealed cartridge bearings by EZO Japan.

Purpose and Rider Benefit

HUNT Bike Wheels, an industry-leading wheel company committed to serving devoted riders, will announce on June 8th, 2022, the HUNT 25 Carbon Gravel Race Disc & 40 Carbon Gravel Race Disc wheelsets. These race-focused wheelsets are the newest additions to the HUNT Gravel Race range and feature our SPRINT SL hub with a hookless/straight side-wall rim, designed to provide the lowest possible weight while maintaining strength and reliability.

As early adopters of tubeless technology, pioneers in aerodynamic disc brake wheel design, and supporters (and employers) of exceptional athletes such as Josh Ibbett (2020 GB Duro Winner & 2015 Trans-Continental winner), HUNT launched the world’s first dedicated gravel wheelset, the 4 Season Gravel Disc, in 2016 and has remained focused on gravel riding and product development ever since.

These wheelsets were built by HUNT to provide lightweight race-level performance for fast gravel riding or racing, with marquee gravel events in mind, such as SBT GRVL, Dirty Reiver, Rule of Three, and Unbound. HUNT laced wide, tubeless, ETRTO-compliant hookless rims to reliable and fast-engaging Sprint SL hubs to create lightweight gravel-specific wheel systems ready to go fast and far, whether in a race or on an adventure.

HUNT 25 Carbon Gravel Race Rider Benefits

The HUNT 25 Carbon Gravel Race offers durability and control when you need it the most. The asymmetric rim profile has been designed with compliance and impact resistance top of mind so riders worry less when hitting rough roads and singletrack.

HUNT 40 Carbon Gravel Race Rider Benefits

Built to provide lateral responsiveness and an aero profile in a lightweight package, the HUNT 40 Carbon Gravel Race is designed to meet the needs of the gravel racer and rider. Wide and lightweight 40mm-deep hookless rims offer durability, quick acceleration and aerodynamic efficiency, intended for use with modern-width gravel race tires.

Hookless Rim Design

HUNT has been developing hookless road rims since 2016, seeking ways to reduce weight and improve performance for riders. With the 25 & 40 Carbon Gravel Race Disc rim development, we were able to push those weight savings further, bringing the final rim weights to a mere 385g and 395g respectively. Due to a simpler manufacturing process, hookless rims can be produced with less waste, resulting in a cost reduction that can be passed on to riders.

Hookless rim profiles also enable a smoother transition of airflow between the tire and the rim, and therefore reduce the wake behind the rim, resulting in lower system drag. The aerodynamic benefits are marginal, but they’re real.

The 25 Carbon Gravel Race Disc wheelset features a fully ETRTO-compliant hookless rim profile (26mm internal) compatible with 35-65mm gravel tires. The 40 Carbon Gravel Race Disc wheelset also features a fully ETRTO-compliant hookless rim profile (25mm internal) compatible with 28-65mm tires. Maximum tire pressure shall not exceed 72.5psi (5bar) for both wheelsets.
