Perhaps the ultimate all-around, non-tubeless, high performance wheelset, the 4.5 debuted the second generation SES profile. It delivers outright class-leading speed while retaining a very low weight and incredible stability.
The SES rim profile has a significantly revised curvature and increased widths that are optimized for 25mm tires in modern frames with greater clearances. This allows air to flow smoothly over the rim – it remains ‘attached’ – even at high crosswind angles and to reattach quicker after a strong side gust. These important advances make the 4.5 both extremely fast and stable for its depth. In challenging conditions, wind-steer is all but eliminated and side force builds and releases smoothly and predictably, so you can ride and race with complete confidence.
How fast is the 4.5? Compared to the first line of SES wheels, the 4.5 essentially matches the aerodynamics of the older 6.7, which was itself ballistic yet much deeper at 60mm front and 70mm rear, and of course heavier with it. Nothing of a similar depth or weight gets close to the speed of the 4.5.

• Class leading aerodynamics and weight
• Incredible stability in gusty conditions
• Second generation SES rim profile
• All-new rim profiles of 48 and 56mm
• Optimized width for 25mm tires
KEEPING RIM BRAKES COOL
With near equal wet and dry performance, 30% less lever force required for the same stopping power and exceptional heat management, it’s no wonder that BikeRadar.com said our latest brake track “sets new standards for carbon wheels”. Your rim brake bike will be given a huge braking performance boost.
There are three elements, all the product of relentless research and development. First is the molded-in brake surface texture which provides more friction and allows water to be cleared almost instantly. Second is the advanced high-temp resin system which eliminates the heat build-up issues that other carbon clinchers can suffer, so you can ride long descents with total confidence. Third is our unique ENVE Black pad compound which is designed to work with the molded texture to provide incredible all-weather stopping power along with good durability.
Need to know:
• The best carbon braking, period. Near equal wet and dry performance
• 30% less lever force required for the same stopping power
• Advanced high-temp resin system eliminates heat build-up issues during heavy braking on long descents
• Specific ENVE Black Carbon Brake Pads included
Timeless technology you can rely on
The SES 4.5 is for cyclists and triathletes looking to minimize the tradeoff between aerodynamics, lightweight, and stability, while retaining tried and true, reliable technology.
A refined shape and construction that yields better acceleration, cornering, impact resistance, and weight savings.
Simplicity meets performance, in a depth for diverse riding.
The SES 4.5 was the beginning of the revolution of the Smart ENVE System. Tested and optimized in the Mercedes GP Petronas Wind Tunnel, the SES 4.5 is the fastest rim on the market when tested on a modern aero road or triathlon frame and compared to rims of a similar depth. The new shape of the SES 4.5 is wider than previous SES models to improve aero performance in modern bicycle frames and to improve ride characteristics when paired with tires between 24mm and 26mm wide depending on your tire brand of choice.
When compared to ENVE’s historic line of SES wheels, the 4.5 essentially matches the aero performance of the previous SES 6.7 which was much deeper rim at 60mm in the front and 70mm in the back, while retaining lower weight and more crosswind resistance.
