The ENVE SES 4.5 AR Disc is an uncompromising aero wheelset that’s perfect if you’re seeking more speed, comfort, and traction over old, broken or poor road surfaces and even the occasional gravel track.

Designed as the ultimate race wheel for Team Dimension Data’s Spring Classics campaign, the SES 4.5 AR brings aerodynamics to all-road performance, giving pro riders the superior grip, rolling resistance and comfort of 30mm tyres over cobbled sections and an aero boost between them.

As with the rest of the SES range, the 4.5 AR derives its name from its rim depths –49mm front, 55mm rear – each with patented dissimilar SES rim geometries. With the SES 4.5 AR, the introduction of road-disc frames with increased tyre clearance has allowed ENVE to take an unconventional approach to wheel design and create front and rear rim shapes that better manage airflow around wider tyres, significantly reducing flow separation.

In addition to dissimilar geometries, the SES 4.5 AR Disc features disc brake specific construction. ENVE has removed the brake track and its heat management material entirely to save weight, improve strength and create an unprecedented ride quality.

The SES 4.5 AR Disc is available as a tubeless clincher and tubular model rim. The tubeless version utilises ENVE’s hookless bead design – technology created for the brand’s M Series MTB wheels that improves aerodynamic performance by aiding airflow from tyre to rim. This design also provides real-world gains in rolling resistance, comfort, traction and a reduced chance of flats.

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.

Every single R45 CL 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 CL hubs are synonymous with silky-smoothness, unbeatable quality and of course that distinctive angry bee sound that resounds from the hub body.

R45 CL 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 CL 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 CL is fully serviceable, you can enjoy peak performance for years to come.

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