HADRON² Ultimate 500 Disc Brake

Top level aero performance on any course, in any conditions, the HADRON² Ultimate 500 aero wheels are at home on twisty mountain passes, as well as for time trial and triathlon courses. Their shallow rim profiles are designed to maximise handling and aero stability in high wind conditions by minimising the sensitivity to gusty crosswinds. The 20mm inner rim width is optimum for minimum rolling resistance with 25mm and 28mm tyres and remains compatible with even wider tyres. Full carbon clincher, tubeless ready construction. UCI approved. Including lifetime warranty for material and workmanship defects and a Fair-Share-Policy for any other riding damage.

Description

The new unmatched benchmark for aero wheel performance. Minimum Aero Drag with Maximum Aero Stability in the wind. 20mm inner rim width, tubeless ready carbon clincher wheels for best possible rolling resistance and to accomodate also wider tyres. Engineered with the continuous learning since Day-1 at Swiss Side, combining our latest aerodynamic research methods from our Formula 1 background and derived technolgies. Compared to the HADRON Ultimate, this latest HADRON2 Ultimate rim shape reduces steering moment by a further 26% for increased stabilty in the windy and gusty conditions, whilst reducing the aero drag by a 10 - 20% depending on the rim depth, also thanks to the new Aerolite II spoke developed in collaboration with DT Swiss. Built with the latest top level 180 DICUT hub, SINC ceramic bearings and the highest quality production through our partnership with DT Swiss, there is zero compromise on performance and quality so you can set new personal best times on your favorite courses.

Product Reviews

HADRON² Ultimate 500 Disc Brake - Bikeradar Review (Dec. 2021)

Robin Wilmott, technical writer for bikeradar.com, has tested our HADRON² Ultimate 500 Disc Brake wheels. Check out what he has to say in his official report.

Verdict: 

If you want a fit-and-forget, reliably rapid all-conditions wheelset, the Ultimate 500 is a classy option.

- Stiff enough for effective sprinting and short, steep climbs, and light enough to maintain a high pace on long ascents.

- For all-round daily riding, they’re an ideal blend of aero and physical efficiency, with no performance or practical compromises.
