ENVE G SES 4. 5 700c Wheel Real-world fast meets off-road. The G SES 4. 5 is built for the full spectrum of gravel - aerodynamic advantage across varied terrain without sacrificing the weight and handling needed for climbing, accelerating, and nimble cornering. A 49mm front and 55mm rear rim depth paired with an innovative 30mm internal width strikes the ideal balance of responsiveness, stability, and speed for gravel riders who place a premium on nimble handling and weight savings alongside aerodynamic efficiency. INNERDRIVE Premium hubs feature ENVE's 100% in-house designed 42mm oversized ratchet drive system with automatic preload adjustment, reduced axle stress, and long bearing life at 326g for the hubset. Wide Hookless Bead technology - borrowed from ENVE's M Series mountain wheel platform - dissipates impact energy for impressive toughness-to-weight. Rims manufactured by hand in Ogden, Utah.
