A 275-gram rim sits at the core of the ENVE SES 2.3 front wheel, representing carbon fiber engineering pushed toward its practical limits for road racing. The complete wheel weighs 558 grams with tubeless tape and valve installed, making the 2.3 the choice for riders who count grams on mountain stages and punchy climbs. ENVE achieved this weight by using continuously running fibers throughout the rim structure, tapering laminates where stress concentrations allow, and removing material everywhere the design permits without compromising tire retention or impact resistance.

The 28mm front depth keeps the wheel stable in crosswinds while providing enough aerodynamic shaping to carry speed through the valleys and flats between climbs. Paired with a 32mm rear wheel in the complete wheelset, the dissimilar depths follow ENVE's Smart System approach of optimizing each wheel for its position on the bike. The front prioritizes handling predictability while the rear captures airflow passing from the rider and frame. At 21mm internal width, the rim works with tubeless tires from 25mm up, with aerodynamic optimization centered around 27mm labeled widths.

Hookless bead construction enables the precise bead seat diameter that tubeless setups require for reliable air retention and tire security. Wide Hookless Bead technology adds a blunt leading edge to the rim profile that dissipates impact energy when you hit potholes or debris, reducing pinch flat risk even at the lower pressures that tubeless allows. This matters on descents where rough pavement meets high speeds.... Read More
