Positioned between two of our most popular Carbon Aero Disc offerings (35 Carbon Aero Disc and our Giro d’Italia stage-winning 50 Carbon Aero Disc), the new 40 Carbon Aero Disc was built for riders looking to lower rotational weight on climbs and rolling terrain, while still benefitting from the aerodynamics of a 40mm-deep, U-shaped rim profile..
The mid-depth, super-wide 27mm rim provides stable and predictable handling while reducing drag across multiple wind yaw-angles. The wider 19mm internal rim bed opens out your tyre profile providing exceptional vibration reduction, grip and low rolling-resistance, especially when ridden at lower pressures with modern-width tubeless tyres.
The straight pull hubs and bladed spokes reduce weight, add strength and respond instantly to accelerations. The freehub body on the HUNT Sprint hub features 48 teeth on the ratchet ring, and treble-tooth pawls, providing incredible 7.5° engagement. Finished with stainless steel bearings which are low-friction to further reduce rolling resistance and increase your speed.

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.
All HUNT wheels models have to pass our harsh cobbled-rolling-road tests for rider weight limits, please see here for more details. 109kgs is the upper recommended rider weight limit for these wheels. Please include the weight of any luggage in your total rider weight when choosing the correct wheels. If a rider is over 90Kgs then an experienced bike mechanic should check the wheel regularly and it is advisable to use tyres at max 90psi as this will reduce the fatigue on the wheelset. 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.
