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.
Note it's important for you to measure your handlebar position prior to purchasing a Longboi stem. The longer Longboi stems on some framesets and bar combinations may put your handlebars in front of the 100mm UCI reach limit (UCI Technical Regulations 2023).
Designed in collaboration with Cycling New Zealand for Tokyo Olympics.

Got that yoga form with this stem, really a massive jump from the 150 I’ve been using for 4 months and I’ve been enjoying this 180 for the last 2 weeks of using it great quality and shipping 🤙🏽
My new head stem is strong, sturdy and compliments my bunch bars and track bike perfectly.
Very happy with my new longer stem.
