Wheelset
Zipp 303 SW
Zipp's 40 mm all-road carbon wheelset with a wide 25 mm hookless rim built for 30-35 mm tyres, and the first Zipp wheel with an AXS tyre-pressure sensor integrated in the rim. It is aimed at mixed surfaces and comfort rather than outright aero speed, so it suits all-rounder and endurance builds more than tri bikes.
Fitted to 2 builds across 2 bikes in the database.
