ENVE G SES 4. 5 Pro 700c Wheel Real-world fast goes off-road. The G SES 4. 5 Pro 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 a 30mm internal width tuned for 44-52mm tires strikes the ideal balance of responsiveness, stability, and speed at modern gravel race pace. The INNERDRIVE PRO hub brings the same technology raced on the World Tour for two seasons, upgraded with a light-action 40-tooth ratchet spring kit and ENVE PRO Ceramic Bearings for a 60g weight savings over the Premium INNERDRIVE at just 281g for the hubset. Wide Hookless Bead technology - pulled directly from ENVE's M Series mountain wheel development - dissipates impact energy at the rim edge for impressive toughness-to-weight. Rims manufactured by hand in Ogden, Utah.
