3T Discus 45 LTD Carbon Gravel Wheelset

3T Cycling is the Italian component brand that partnered with Cervelo when it launched the Aspero gravel bike — and the Discus 45 LTD is the natural wheelset for this pairing. Its 45 mm depth "Discus" toroidal profile (wider than tall) was designed specifically for wider tubeless tyres (32–45c) running at low pressures, preventing the aero penalty that occurs when a tyre bulges wider than the rim. Cervelo CA Gravel, Colnago G4X, and Pinarello Dogma X all accept the Discus 45 LTD as an OEM or build-upgrade specification, each brand seeking the aerodynamic benefit on gravel terrain.
