The G SES 4.5 PRO is built for the full spectrum of gravel. This is versatility without compromise—shaped for aerodynamic advantage across varied terrain, while keeping weight in check for climbing, accelerating, and nimble handling. 

With a 30 mm internal width and 49 mm front / 55 mm rear rims, the G SES 4.5 PRO strikes the ideal balance of responsiveness, stability, and speed. The G SES 4.5 rim paired with the Pro Innerdrive hub results in an impressively low 1480‑gram wheelset weight makes it class‑leading against any aero‑gravel competitor.
