The longest of longboi’s — measuring 170mm, 160mm or 150mm — this sprint stem extends your reach out for a more aerodynamic position to get the most out of the UCI geometry regulations for sprint events.

The Elite Longboi is the stiffest stem we have tested to date!

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 limit for track sprint events.

Designed in collaboration with Cycling New Zealand for Tokyo Olympics.

Is the size you’re after sold out? Some sizes, especially the longer ones, sell out fast. We’re currently producing another manufacturing run of these stems, which we expect to be ready in October.

The Long Boi had a quick track outing today - verdict is that it is awesome. Able to get the necessary reach with a more forward saddle position, so more weight over the front wheel, making the bike handle better. - Eugene Bonthuys
