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 created lightweight gravel-specific wheel systems ready to go fast and far, whether in a race or on an adventure.

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 which can be passed on to riders.

Hookless rim profiles also enable a smoother transition of airflow between the tyre 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 tyres. The 40 Carbon Gravel Race Disc wheelset also features a fully ETRTO-compliant hookless rim profile (25mm internal) compatible with 28-65mm tyres. Maximum tyre pressure shall not exceed 72.5psi (5bar) for both wheelsets.
