Read the full aerodynamics report on the 50 Carbon Aero Disc

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 tire 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 tires 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.
