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).

Customer Reviews
Absolute Confidence on the Ride
I recently upgraded my Stomm stem to the Longboi, and it's nothing short of a game-changer. This stem has redefined my expectations for what a stem can be.
Unmatched Design
From the moment I saw the Longboi, I knew it was special. The reverse bolt pattern is not just aesthetically pleasing, it feels incredibly secure and flex-free in the handlebars. Unlike other stems that feel bulky or generic, the Longboi is precision crafted with a purpose.
Built to Handle the Pressure
As a competitive cyclist, pushing my limits is everything. The Longboi gives me the unwavering confidence I need to sprint for victory. I've reached UCI limits with my current setup, and the stem feels rock solid. The hardware is top-notch, and the overall quality is unmatched by anything else on the market. There's no doubt in my mind that this stem can handle the immense torque of a World Championship sprint finish.
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.
Fantastic how quickly it gets here in the NL from NZL.
