Cycling Weekly Verdict

Koo’s Supernova sunglasses come with a premium pricetag but are incredibly lightweight (22g measured, 21g claimed) for the wide coverage they offer. With notably springy arms, there’s no pinching or squeezing – the fit is very comfortable. However, this does make the glasses a little less secure for riding on rough roads and trails.

Reasons to buy
  • +

    Very lightweight

  • +

    Unobstructed field of vision

  • +

    Comfy fit

Reasons to avoid
  • -

    Lens could provide more coverage

  • -

    Rattily on rough terrain

After winning the 2019 National Single-Speed Cross-Country Mountain Biking Championships and claiming the plushie unicorn (true story), Stefan swapped the flat-bars for drop-bars and has never looked back. 


Since then, he’s earnt his 2ⁿᵈ cat racing licence in his first season racing as a third, completed the South Downs Double in under 20 hours and Everested in under 12.


But his favourite rides are multiday bikepacking trips, with all the huge amount of cycling tech and long days spent exploring new roads and trails - as well as histories and cultures. Most recently, he’s spent two weeks riding from Budapest into the mountains of Slovakia
