ENVE 45 Foundation Innerdrive Wheels
These dynamic carbon road wheels are ideal for racers and soloists seeking to push their own best efforts. With more than a decade of experience building carbon wheels, ENVE brings its know-how and tech to the masses with its Foundation 45 wheels. They combine aero properties in a tubeless-ready design along with pinch flat protection.
To ensure a performance benefit for riders of all abilities, ENVE used wind tunnels to test its ENVE 45 wheels in-frame at multiple speeds ranging from 20mph to 30mph.
The brand went with a hookless tubeless rim profile for a safer, more reliable tire fit. That way, riders can run whichever pressure they want to cater to comfort, traction, and rolling efficiency. These wheels also use ENVE’s patent-pending Wide Hookless Bead, a design element at the leading edge of the rim that dissipates impact energy and reduces the likelihood of pinch flatting your tubed or tubeless tire.

Another big technology showcased in the ENVE 45 is the Innerdrive drive mechanism. The Innerdrive puts oversized steel ratchets inboard and over the bearings to reduce stress on the axle and bearings without compromising the rider’s reliable engagement.
ENVE makes and assembles all of its rims in Ogden, Utah. ENVE’s Lifetime Incident Protection program and 5 Year Factory Warranty cover the ENVE 45 wheels.
