4/5
Aerodynamic wheels with a depth of 85mm are usually the preserve of time trialists, triathletes or, occasionally, professional riders on still, flat days. The 858 NSWs, however, might just change all that.
The rims use Zipp's Sawtooth profile, inspired by the tubercles on a humpback whale's fins that improve its efficiency through the water. The wavy inner profile drifts between 82 and 85mm deep, to act like a deeper rim aerodynamically while, at the same time, being more stable in crosswinds: best of both worlds! The rim is 23mm internally to suit wider tyres (it's optimised aero-wise for a 28mm tyre) and, like all of Zipp's carbon rims, it uses a hookless rim profile to suit tubeless tyres.
The biggest difference, however, is in weight. At 1,529.8g per pair, the new 858s are 243g lighter than the previous model and exceptionally light for wheels this deep.

Air Apparent - Pollution hasn't gone away. It's still there in every lungful, even if we can't see it in the air or on the news. But there are reasons to breathe easier, thanks to pioneering projects using cycling 'citizen scientists'. Rob Ainsley took part in one...
The toxic effects of pollution have been known about for years. 'Just two things of which you must beware: Don't drink the water and don't breathe the air!' sang 1960s satirist Tom Lehrer.Over recent decades, though, pollution has dropped down our list of things to worry about, thanks to ominously capitalised concerns such as Climate Change, AI, Global Conflict, Species Collapse, etc. That doesn't, unfortunately, mean the problem has expired. Air quality often exceeds safe limits, with far-reaching and crippling effects on our health.
