Positioned between two popular Carbon Disc offerings (30 Carbon Disc and 50 Carbon Disc), the 40 Carbon Disc was built for riders looking to upgrade their experience with quicker acceleration and lower rotational weight on climbs and rolling terrain, while still benefitting from the aerodynamic gains offered by a 40mm-deep, U-shaped carbon rim profile. Updated with wider rim dimensions and an all-new ratchet hub system, the 40 Carbon Disc is optimized for 25mm-35mm tyres for fast road riding and racing, increasingly popular all-road terrain, as well as gravel riding (ETRTO compatible with tyres ranging from 25mm-55mm).
The mid-depth, 30mm-wide carbon profile provides stable and predictable handling while reducing drag across multiple wind yaw-angles. The wider 22mm internal rim bed opens out your tyre profile providing exceptional vibration reduction, improved cornering traction and low rolling-resistance, especially when ridden at lower pressures with modern-width tubeless tyres.
The HUNT team have paired the wide hooked rim with new H_Ratchet 36T SGL hubs, offering a rapid 10-degree engagement angle, in a reliable, easy-to-service and long-lasting single-sided ratchet drive system. Increased engagement surface area improves power transfer and longevity of the hubs, while using less material compared to a spring-and-pawl system, resulting in a light but robust hub system designed and tested to cope with the torque demands of road or gravel drivetrains. Hand-built with top-of-the-range, easily serviceable Pillar PSR triple butted J-bend spokes and precision sealed cartridge bearings, this wheelset is ready to speed up your road, CX, or gravel rides.

Warranty, HUNT Rolling Road Tests & Weight Limits
A full 3 years from purchase date warranty is offered to the original purchaser only on all Hunt bike wheels against material or workmanship defects, please click here to read full details.
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. While our carbon layup processes are very precise, a 3% variance (lower or higher) in total system weight is completely normal in carbon fibre manufacturing.
All HUNT wheels models have to pass our harsh cobbled-rolling-road tests for rider weight limits, please see here for more details. Max system weight 273lbs (system weight – total weight of fully kitted up rider, bike and luggage). If a rider is over 203lbs then an experienced bike mechanic should check the wheel regularly. We are cyclists ourselves and do of course go above and beyond to offer excellent service if you ever do experience any issues. We carry full spares at very reasonable prices and offer complete support.
60 Day Ride & Return Period. We are certain you'll be impressed by the acceleration, low-weight, speed and durability of our wheels. We are cyclists and as such strive to offer class leading service and support. Buy with confidence, if for any reason you wish to return the wheels for a full refund of your order you can do so up to a full 60 days after you receive them whether they have been ridden or not. Please note we cannot offer refunds on wheels that have suffered from crash damage but do offer a crash replacement discount.
