KOO Eyewear - RA Cycles

Gafas KOO

KOO Eyewear is the sunglasses brand created by KASK — the Italian helmet maker trusted by Team Ineos Grenadiers and professional cyclists worldwide. Born in Bergamo, Italy and designed to work alongside KASK helmets, KOO brings the same precision engineering philosophy to eyewear: Zeiss lenses fitted as standard across every frame, construction engineered for cycling’s specific demands, and styling that performs on the road or off it.

The RA Cycles KOO selection covers the full lineup — from the performance-focused Supernova and Hype, to the versatile Nova, Demos, and Alibi, through to the polarized Cosmo for rides where light management matters most. Every model is built around Zeiss optics, with Active Airflow ventilation to prevent fogging on long climbs and hard efforts. Official eyewear partner of BORA-hansgrohe and the Strade Bianche.

About KOO Eyewear

KOO Eyewear was created by KASK, the Bergamo-based Italian helmet brand, as a companion eyewear line designed specifically for cycling. Every KOO frame is built around Zeiss lenses — fitted as standard across the entire range — and engineered to integrate with KASK helmet designs. The brand is the official eyewear partner of BORA-hansgrohe and an official partner of the Strade Bianche, one of cycling’s most prestigious one-day classics. More on the brand and its technology at KOO’s official website.

RA Cycles stocks the complete KOO lineup. The Supernova and Hype sit at the performance end — lightweight race frames with wide Zeiss lens coverage for maximum vision on fast descents and sprints. The Nova, Demos, and Alibi offer a versatile road and all-day riding profile. The Cosmo is available in a polarized version for riding in variable or bright light conditions. The Open and Open Cube round out the range with a more open-frame design, and the Optical Clip Evo provides a prescription insert for those who need it.

For the broader protection lineup at RA Cycles, explore KASK helmets — designed to pair directly with KOO eyewear — or browse the full eyewear and bike helmets selections.

50 YEARS AND COUNTING

That half-century belongs as much to you as it does to us. The riders who kept coming back, who sent their friends, who trusted us with bikes that matter — you're the reason we're still here. Here's to the next fifty.
