The ENVE SES 4.5 Wheelset is a rim brake specific wheelset that strikes the perfect balance between responsive acceleration and aerodynamics. From training to racing it's the ultimate everyday wheelset for road riders and triathletes.

Designed by aerodynamicist Simon Smart and developed using in-frame aero testing at the Mercedes-AMG Petronas wind tunnel, the SES 4.5 has also undergone countless miles of real-world testing by Team Dimension Data riders.

Like all ENVE SES wheels, the mid-depth SES 4.5 gets its names from its depth-optimised rim shapes – 48mm front and 56mm rear. The front rim is slightly wider to aid crosswind stability and handling while the narrower rear rim improves overall airflow attachment for better aerodynamics.

This fast, stiff, lightweight wheel is incredibly versatile – as at home climbing in the Alps as blasting through a triathlon bike leg or taking on criterium races where acceleration and cornering are the names of the game.

Aiding the SES 4.5's all-conditions performance is ENVE's full carbon moulded brake track. This textured surface with high temperature resistance achieves exceptional stopping power and equal performance in wet and dry conditions. Braking force at the levers is also decreased by 30% compared to the previous generation brake track, allowing you to reduce speed with confidence through the tightest turns.

Industry leaders in carbon fibre, every ENVE rim is handmade from raw uni-directional carbon at ENVE's headquarters in Utah, USA. The bespoke construction process utilises rim-specific carbon laminates, moulded spoke holes, removable bladders, and a gorgeous paint-free finish to reduce weight while maintaining strength, stiffness and allowing the beautiful handmade quality to shine through.

The SES 4.5 remains in the ENVE range for cyclists whose bikes are incompatible with the newer, wider, SES 5.6 – an evolution of this wheel's design. The SES 4.5 is optimised for 25mm tyres but is not tubeless compatible.

Every single R45 hub is engineered, manufactured and assembled in-house at Chris King’s HQ in Portland, Oregon. Fully serviceable and with a five-year warranty, you can be confident that you’re investing in an elite performance product that has been built to last. R45 hubs are synonymous with silky-smoothness, unbeatable quality and of course that distinctive angry bee sound that resounds from the hub body.

R45 hubs utilise an innovative 45-tooth RingDrive system for minimal drag and almost instant engagement, translating power from your legs directly into forward propulsion. As engagement systems go, this really is the best of the best. The legendary bearings and heat-treated, surgical grade steel races employed in the R45 not only form a super-smooth integrated system but actually become faster as they burnish with use – wearing in, rather than wearing out. Because every R45 is fully serviceable, you can enjoy peak performance for years to come.

Available in a wide variety of colours, R45 hubs enable you to give your bike a truly custom flair. Please note that some hub colours may require bespoke shipment from the USA and may take a little longer to acquire.
