What Our Gearhead(R) Experts Are Saying: "I've been hyped for the 4. 5 PRO ever since the early specs dropped. ENVE managed to make this wheelset lighter and faster without giving up that signature smooth control. The new hub rolls insanely well-and the handling is confidence-inspiring, even on gusty descents."We chase marginal gains with every pedal stroke, and the ENVE SES 4. 5 PRO delivers where it counts-weight, aerodynamics, and rolling efficiency. This next-gen wheelset is engineered for those who demand podium-ready performance and day-in, day-out reliability for training, racing, or pushing personal bests. The SES 4. 5 PRO blends a 49mm front and 55mm rear rim depth for aerodynamic speed that still feels stable in crosswinds. It rolls on ENVE's all-new Innerdrive PRO hubset, featuring ceramic bearings for frictionless movement and ultra-quick engagement. Tubeless-ready, optimized for 28mm tires, and weighing just 2lb 13. 7oz (1295g) with valves and tape, this is the fastest, most refined version of the 4. 5 yet.
