The fastest alloy disc-brake wheelset in the world.

34 DEEP | 26 WIDE EXT | 20 WIDE INT | 1565G

The Purpose

After years spent testing and developing in the wind tunnel and on the open road (and the subsequent launch of our 48 Limitless Aero Disc wheelset), HUNT is proud to introduce the 34 Aero Wide Disc SL - the world's fastest alloy disc-brake wheelset.

Wind tunnel proven against world leading wheels. See the 34AWD test report for full technical details of our wind tunnel testing methodology, including data/graphs and the full range of wheels we tested against.

Designed by HUNT's in-house engineering team.

Everything we learned when pushing what is aerodynamically possible with a carbon disc-brake wheelset, has been applied to an alloy model that embodies the same philosophy: be the absolute fastest drop-bar wheelset.

ALLOY? IN A WIND TUNNEL?

Until now, aerodynamic development has lagged behind on alloy wheelsets. So much so, that after having invested our time and knowledge into the 34 Aero Wide Disc, it is faster than a (carbon) Zipp 202 NSW when paired with a 28c tire. The assumption that carbon is inherently faster is untrue, and now tangible aerodynamic performance has been made accessible for all.

WIDER TIRES & WIDER WHEELS | RIDE FASTER

Leading rim-brake wheels have been at the 27-28mm wide mark for some time, with undisputed aero benefits over narrower designs. However, they are aerodynamically limited by rim brake calipers limiting the maximum width of the brake track. Further, most are optimised for narrower tires. 23mm tires used to be the standard… but for us, you and most pro riders, 25/28 and even 30mm tires are the preferred choice. Let’s face it: when leaning in on the final turn of a mass bunch sprint or descending sweeping alpine bends, you want serious grip! Plus, the lower rolling resistance benefits of 25 and 28mm tires* mean that road disc aero wheels should be specifically designed around these wider tires. Accordingly, this wheelset has been designed using schematics and feedback from Schwalbe's own engineers.
(*Especially rider-system benefits, wheel & tire only tests do not include rider damped losses, and how lower pressures reduce these losses by reducing rider movement. This is a whole other area we will be releasing scientific data on.)

THE RESULTS…

The wind tunnel data we recorded is shown against the full range of incumbent world-class aero wheels in the charts below. The results speak for themselves. It’s been hard work but it’s been very worthwhile. This process and the knowledge gained from pushing the boundaries of aero wheel development creates huge opportunities to serve you with a wide range of world leading aerodynamic wheels…this is just the beginning! Thank you.

Key Features

The fastest alloy disc-brake wheelset in the world.

Rims | Aerodynamicist rim profile with similar rounded profile to our Limitless wheels. 24mm external width at the hook, but tapering to 26mm lower down to optimise airflow. 6069-T6 alloy (+69% tensile strength vs 6061-T6)
Tires | Tubeless-ready for lower weight and rolling resistance. As with all our current HUNT rims, these wheels have a normal hooked sidewall and are suitable for all clincher road tires including Continental.
Hubs | Sprint SL straight-pull hubs. 15mm diameter 6066-T6 body and axle for supreme strength-to-weight. Circular dropout interface steps for added security in fitment. 3x treble-tooth pawls, resulting in 7.5˚ engagement. Steel spline inserts protect the freehub body.
Spokes | Pillar Wing 20 spokes with aerofoil profile. Tested and proven to provide aerodynamic advantage over flat or bladed options both from Pillar and other competitors.
Axles | Easily adaptable & we fit them for you. Fit all current axle sizes and are easy to change; Front - QR, Bolt thru 12/9mm, Rear - QR, Bolt thru 12x142, 12x135, 10x135.
Included | Tubeless tape & valves, spare spokes, axle adapters (please fill in the simple form after checkout to select your required size).

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. 100kgs 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 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. 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.
