Koo Spectro Sunglasses review

Stylish and secure, but does their performance match their price?

Cycling Weekly Verdict

The Koo Spectro Sunglasses have a comfortable and secure fit, with good anti fogging and a clear lens that can span a surprising range of light levels. Although on the larger side, they aren’t at the extremes, and so have a more modest style about them. The only criticisms to make regard the price, which is a fair bit higher than some of the competition, and the slight obstruction of the peripheral vision.

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
