In 2016, ENVE launched the SES 4.5 AR, a wheelset that included features such as tubeless only construction and aerodynamic optimization around high volume 28-32mm tyres. Building on this, ENVE has announced the expansion of the SES AR line-up to include the all new SES 3.4 AR.
According to the company, the SES 3.4 AR promises to deliver:
- Aero efficiency when using 28mm to 32mm tyres
- Improved rolling resistance efficiency
- Wide Hookless Bead Anti-Pinch Flat Technology
- Disc brake specific materials and construction for ride feel, durability, and weight savings
- Light weight for climbing performance
- Road tubeless optimized design for uncompromising reliability
The SES 3.4 AR, like all SES rims features asymmetric rim geometries between the front and rear rims. This maximizes aerodynamic performance for the airflow unique to the front and back of the bicycle.
In this case, the front rim measures in at a depth of 39mm with an external width of 31.2mm while the rear comes in at 43mm deep and 30.5mm wide. The internal rim width of both the front and rear rims comes in at 25mm. The extreme width of the SES AR family when compared to a modern but traditional aero road wheel is the result of an aerodynamic development project to optimize drag reduction and stability for high-volume performance oriented tubeless road tyres.
“A little over three years ago, we stood on the side of the Arenberg Forrest sector of Paris-Roubaix as the new official wheel sponsor of what is now Team Dimension Data, watching our wheelsets be put through the paces in this environment for the first time,” said ENVE’s VP of Product, Jake Pantone.
“During this test session, our conversations turned to aerodynamics and the question of whether we could recover the aero losses of high volume tyres with a radical rim shape was raised.
“Ultimately, the answer was ‘yes’, and the SES 4.5 AR was born. It has taken a few years for frame manufacturers to produce the bikes with tyre clearances required to accommodate these wheels, but the bikes are here now, and the SES 4.5 AR has become our most popular wheelset in North America.”
ENVE is touting the new SES 3.4 AR as the most versatile road wheel in its line-up given its lightweight full carbon construction, and ability to achieve top shelf aerodynamic performance with 28mm tyres.
ENVE is offering the SES 3.4 AR as a rim set, or complete wheelsets built with either an ENVE Disc or Chris King R45hub set. The SES 3.4 AR starts at a complete wheelset price of US$2550.
