The ENVE 45 is a modern multi-purpose road wheel in every way. Riders with inclinations toward racing and hard solo efforts will find the rim’s drag-taming, and cross-wind defying shape a welcome upgrade to their rides. Those with inclinations towards the road lost and forgotten will find the rim’s width and anti-pinch flat technology complementary to higher volume tubeless road tires. All said, the ENVE 45 is everything that the dynamic modern road rider needs, and nothing that they don’t.
