ENVE - Foundation 45 DISC wheels

Foundation wheels are a tribute to the original ENVE road wheels that were introduced to the market in 2007. Each wheel in the Foundation collection features a host of essential exclusive technologies that make them "best in class".

To achieve the low drag, high stability performance provided by the rim shapes, ENVE drew inspiration from the development of its SES rims. The main difference between Foundation and SES is that Foundation rim geometries are matched (front and rear), whereas SES rims feature shapes specially optimized for the front and rear positions of the bike. Thanks to this development, Foundation ENVEs offer similar or better drag reductions than even the most high-end competitor wheels.

Technologies

TUBELESS System

ENVE Foundation wheels are compatible with Tires Tubeless tires. Note that these wheels have been designed to be more efficient when combined with a 25 mm tubeless road tire, and are of course compatible with Tires Tubeless clincher tires for the more reluctant.

Wide Hookless Bead

ENVE Foundation wheels also feature ENVE's Wide Hookless Bead technology. This technology is defined as a wide rim flange surface. By creating this greater width, impacts from edges, potholes and debris are spread over a wider area, reducing the likelihood of pinch flats. This feature also increases the rim's impact resistance.

Foundation Road Hub

A top-of-the-range hub, the Foundation Road uses ENVE's proven ID360 40t ratchet drive mechanism and Care -free automatic preload system aptly named Perfect Preload ™.

This system eliminates the possibility of the hub developing backlash. It also eliminates the need for consumers to adjust the preload themselves. With regard to

Bearings: the Foundation RoadHub is equipped with fully sealed, high-quality NTN steel bearings.
