Rear wheels in the SES lineup run deeper than their front counterparts for a specific aerodynamic reason. The ENVE SES 3.4 Rear Wheel uses a 43mm rim depth compared to the 39mm front to recapture airflow as it passes from rider and frame toward the back of the bike, maximizing drag reduction where it matters most. This differential depth approach comes from ENVE's Real-World Fast development philosophy, which prioritizes actual riding conditions over pure wind tunnel numbers.

The 25mm internal rim width supports high-volume tubeless tires in the 27-28mm range that ENVE optimized the aerodynamic profile around. Running wider tires at lower pressures improves comfort, traction, and rolling efficiency without sacrificing speed, and the hookless bead design ensures precise tire retention by maintaining exact ETRTO bead seat dimensions. ENVE's Wide Hookless Bead technology adds a feature at the leading edge of the rim that creates a more forgiving surface during impacts, reducing the likelihood of pinch flats that can still occur with tubeless setups when you hit something hard enough.

The INNERDRIVE Premium hub handles the drive side duties with oversized steel ratchets positioned inboard over the bearings. This placement reduces stress on both the axle and bearing surfaces while delivering consistent engagement. Four interchangeable ratchet options ranging from 40 to 100 teeth let you tune engagement feel based on your riding style, whether you prioritize efficiency on long rides or instant response for technical terrain. The straight-pull spoke interface uses a single spoke length across all positions and includes anti-twist spoke holes that prevent spoke wind-up during tensioning or riding.... Read More
