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.
The ENVE Alloy Road Disc Hub blends a high-strength machined hub shell with premium components to deliver exceptional performance and virtually no maintenance.
Taking cues from ENVE's award-winning carbon hub design this disc-brake specific alloy hub has been five years in development to ensure a superior ride experience and low weights of just 126g front and 250g rear. With Centerlock compatibility and a six-bolt adapter included, the ENVE Alloy Road Disc hub is ready for your disc-equipped road, gravel or CX bike.
Made entirely in ENVE's Utah headquarters, the hub shell is machined from a forged billet with geometry designed to create a responsive and optimally stiff wheel.
ENVE has chosen a paired spoke hole setup in the hub flange, which allows more material to be removed, reducing weight. The design also improves bracing angles, enhancing drive stiffness, efficiency and ride feel for more confidence-inspiring accelerating and cornering.
The hub's axles have also been designed from the ground-up by ENVE and feature the brand's pioneering Perfect Preload system. By positioning a calibrated wave washer between the bearing and a snap ring installed on the axle, bearing pre-load is consistently optimised. This eliminates bearing play and the need to adjust pre-load yourself, reducing premature wear.
Also increasing reliability are the custom, premium stainless steel bearings and races, which outperformed ceramic bearings in ENVE's lab tests and are ideal for British riding conditions. These long-life components are enhanced by full-contact bearing seals on outboard bearing faces and non-contact seals on internal faces to improve rolling efficiency. All this means the hubs roll with utter smoothness from day one and maintain their performance for thousands of miles without the need for servicing. This makes the ENVE Alloy Road Disc Hub virtually maintenance free.
The proprietary freehub body is machined from strong 7075 alloy and anodised to reduce cog bite. ENVE has created a 40-tooth, nine-degree ratchet design with a single spring that gives exceptional drive response under power. A removable rubber gasket also changes the tone of the freehub when freewheeling.
The freehub body can be swapped from Shimano to Campagnolo or SRAM XD-R versions without the need for tools or re-dishing the wheel.
