Giro Aries Spherical Helmet Montreal '74 Collection

The Giro Aries Spherical Helmet Montreal '74 Collection is a limited-edition release marking the 2026 UCI Road World Championships in Montréal, September 20–27. It honors the 1974 Worlds, the first ever held outside Europe, where Eddy Merckx won on Mount Royal. Sunset gradients and reflective details echo that moment in a bright palette built for visibility as the days grow shorter. Beneath the livery is the full Aries Spherical: Spherical Technology powered by Mips redirects rotational forces in certain impacts, dual-density Progressive Layering manages high- and low-speed hits, and a DryCore brow pad keeps sweat out of your eyes. At only 270 grams in size medium, with 24 Wind Tunnel vents and the Roc Loc 5+ Air fit system, it feels like it isn't there.
