30 Deep | 26 Wide Ext | Tubular | 963g
Sub-1000 Gram Tubular Disc Brake Wheelset for Hill Climb Racing.
30 DEEP | 26 WIDE EXT | TUBULAR | 963G
The Purpose
Inspired by the passionate British Hill Climb community and developed with input from HUNT-supported athletes, the Hill Climb SL Disc is a hyperlight and minimalist tubular disc-brake wheelset designed specifically for smashing KOMs and PRs from your local wall to the national championships.
Ready for the next generation of ultralight disc brake-equipped road bikes, with 30mm deep carbon tubular rims, fully true-able and replaceable UD carbon TaperLock spokes and an ultralight HUNT H_Ratchet UD SL hubset with 9-degree engagement, the wheelset comes in at an ultra-light 963 grams.
Disc-specific tubular profile. Important; please note these are for Tubular tires only and will not work with normal clincher or Tubeless tires.

TaperLock UD Carbon Spoke Technology
HUNT first launched UD Carbon Spoke wheelsets in late 2019, utilizing the now-proven TaperLock carbon spoke technology. The TaperLock system offers riders fully serviceable carbon-spoked wheels that can be trued like any other. With significant increases in lateral responsiveness (see testing info), they have been engineered to provide a responsiveness-to-weight ratio previously unseen on serviceable wheels that delivers your power to the road as effectively as possible.
Tubular Carbon Rims
Working with the world’s best carbon rim suppliers, the HUNT team developed this lightweight climbing wheelset with an ultralight but robust 30mm-deep wheelset that offers a 26mm width, ideal for modern width tubular tires capable of providing the traction needed to fly up steep hills, and the strength required to get back down safely. Disc-specific tubular profile. Important; please note these are for Tubular tires only and will not work with normal clincher or Tubeless tires.
H_Ratchet UD SL Hubset
CNC’d 6066-T6 heat treated aluminium alloy body, the H_Ratchet UD SL hubset takes minimalism to a level not-yet-seen from production wheelsets. The 40-tooth ratchet drive offers 9-degree engagement with pop out end caps for easy serviceability and a drilled out high-strength axle and freehub body (Shimano HG) for further weight reduction. The HG freehub body includes the HUNT signature anti-bite steel insert for protection against cassette gouging, with alloy splines removed to save precious grams.
