Swiss Side’s new Hadron 485 and 800+ aero wheels will be available to pre-order from 26 March. They will join the brand’s existing Hadron 625 wheelset and are claimed to offer industry-leading performance for less than half the price of Zipp’s equivalent wheelsets.
The company, founded by Formula 1 engineer Jean-Paul Ballard and action sports industrial designer George Cant, has been at pains to validate its aero designs in a transparent manner, and last year undertook a wind-tunnel test in front of press to prove the wheels’ merits.
The 62.5mm deep Hadron 625 was pitted against a wealth of other brands, including Zipp, Mavic and Shimano Dura-Ace, and was found to top the leaderboard for similar depths while also showing numbers almost equal in performance to Zipp’s 82mm 808 Firecrest wheels.

Given the Hadron 625’s stellar performance against established competition, we’d expect the new Hadron 80+ wheelset – which offers 80mm rim depth on the front and 85mm on the rear – to be similarly spectacular against the wind. Swiss Side’s own test results show a 2.4 per cent reduction in drag power (the power needed to push 45km/h in the tunnel) compared to the 625.
