🔵 Zipp 303 S Carbon Tubeless Wheelset
The Zipp 303 S is the entry point into Zipp's carbon road wheelset range — 45 mm depth at a lower price point than the 303 Firecrest, making it the standard OEM wheel on mid-spec builds from Trek, Cervelo, and BMC. Its StrikeThrough technology (carbon rims with aluminium braking track replaced by full-carbon rims) is standard across the 303 S range; the Firecrest toroidal profile appears at the rim's widest 29 mm external width. Trek fits 303 S to the Domane SLR 9 endurance build; Cervelo pairs it with their disc brake S5 configurations.
