Elite Longboi Stem

“So long, on the track you’re practically riding in your own slipstream”

The longest of longboi’s, this sprint stem extends your reach out for a more aerodynamic position to get the most out of the UCI geometry regulations.

The Elite Longboi is the stiffest stem we have tested to date! The stems have exceeded 2x the fatigue and static overload ISO requirements for racing bicycle steering components.

Designed in collaboration with Cycling New Zealand for Tokyo Olympics.

Geometry:

Traditional stem measurements like length and angle don’t easily show you where the stem actually places your handlebar. This calculator uses your bike’s head tube angle to determine the exact reach and stack coordinates of the Elite Longboi Stem - giving you precise data to optimise your fit.
