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 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.

Ever had trouble fitting a new stem to a fork only to find that the steerer tube is now too short? The Velobike steerer tube extender raises the height of your steerer by up to 18mm. Precision machined from aluminum, the light weight extender means you no longer have to purchase a new fork for your frameset.
Particularly when using the longer 15mm and 18mm extenders, you may require a longer top cap bolt. Standard bolts are normally 30mm long. We sell top caps with a longer 40mm titanium bolt for the steerer tube extenders.
3mm, 10mm, 15mm and 18mm extension heights available
50mm deep expansion plug
Standard M6 insert thread for stem top caps
Suitable for aluminium and carbon steerer tubes
Fits 1 ⅛ (1.125” / 28.5mm) steerer tubes
Tighten up to 6N/m
Available in black (to match a carbon steerer), or silver (to match an aluminium steerer)
We recommend to epoxy bond them into your steerer tube for best security
Mine has been great moving from a Thomson to a Zipp stem and needing the height back. Handy product. benxlehner
