Integrated Aero Headset w/Crown Race IS52/IS52

The ENVE Integrated Aero Headset pairs an IS52 upper cup with an IS52 lower cup, giving frames built to this standard a tidy, fully integrated appearance at the head tube junction. The kit ships complete with a crown race included, removing the need to source a separate part before installation on a compatible frame.

Compatibility extends to tapered steerer tubes, with a 1-1/2 inch lower section stepping up to a 1-1/8 inch upper section, the arrangement found on many modern road and gravel frames. Riders replacing a worn headset or building up a frame from scratch can use this kit to match the stock bearing configuration without hunting for individual cups or a crown race separately.
