A RACE-FOCUSED HOOKLESS GRAVEL WHEELSET BUILT TO OFFER VERSATILITY FOR THE HARSHEST AND STEEPEST DAYS.
25 DEEP | 33 WIDE EXT | 26 WIDE INT | 1380G
The Purpose
We crafted the new HUNT 25 Carbon Gravel Race wheelset to offer maximum versatility and exceptionally low weight. Laced to our lighter, race-ready Sprint SL hubs, offering rapid 7.5-degree engagement for light and fast gravel riding or racing across technical and varied terrain.
Long-time advocates of tubeless technology for riding on and off road, HUNT’s development into hookless rims began back in 2016. With the 25 Carbon Gravel Disc rim development, we were able to push boundaries of rim weight-saving further, bringing the final rim weights to a mere 385g. As well as having that performance benefit, 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.
A wheelset designed to offer control and speed for the fastest gravel rides. Tubeless, ETRTO compliant hookless rims, laced to a reliable, fast-engaging Sprint SL hub for a system ready to face any race day conditions.
ASYMMETRYIC PROFILE
Durability and control when you need it the most. The asymmetric rim profile on the 25 Carbon Gravel Race has been designed with compliance and impact resistance top of mind so you can worry less.
HOOKLESS/STRAIGHT SIDE-WALL DESIGN
25mm-deep and 33mm-wide external rim profile, featuring a hookless/straight-sidewall and ETRTO-compliant tubeless rim, designed for gravel tubeless tire compatibility.
SPRINT SL HUBS
All-new Sprint SL hubs featuring the same strength and power transfer in a lower weight package, meaning more of your power pushing you forwards. The hub shell is 6066 series alloy, offering a greater strength-to-weight ratio than lower 6000 series alloys. Large 15mm diameter hub axles for climbing and out-of-saddle sprinting responsiveness. Circular dropout interface steps ensure a secure fitment.
