MIXED DEPTH PERFORMANCE, NOW IN DISC FORM.
40/50 Deep | 27 Wide Ext | 19 Wide Int | 1458g
The Purpose
Many of you asked about us bringing the benefits of mixed depths over to our disc-brake range, and so of course we listened. Going deeper on the back provides additional aerodynamic advantages, but the shallower front end improves stability.
Pro road races, criteriums, and even time trials, are being won by disc-brake bikes with increasing frequency. The revolution is happening, and to capitalise you will need an aero wheelset that delivers speed in buckets. Introducing the 4050 Carbon Aero Disc.
The super-wide 27mm rim provides superior aerodynamic performance. The U-profile serves up great handling and reduces drag across multiple wind yaw-angles. The extra-wide 19mm internal rim bed opens out your tyre profile providing exceptional vibration reduction, grip and low rolling-resistance.
The straight pull hubs and bladed spokes reduce weight, add strength and respond instantly to your 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. Perfect for when the hammer goes down and you need an instant response. We’ve even upgraded to LU/LB bearings which are low-friction sealed on the internal face to further reduce rolling resistance and increase your speed whilst maintaining excellent sealing on the exposed faces. The latest breed of tubeless tyres give-up nothing in weight to their clincher counterparts, as well as removing the tube for weight saving and reducing rolling resistance, so tubeless was essential.

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. 220lbs 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 172lbs then an experienced bike mechanic should check the wheel regularly and it is advisable to use tires 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.
60 Day Ride & Return Period. We are certain you'll be impressed by the acceleration, low-weight, speed and durability of our wheels.
