Steerer Tube Extender

RRP $100.00

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.  

Specifications:

  • 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

  • 6061 aluminium

  • 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
FAQ’s:
  • Will this fit any bike? The extender can be fitted to any bike with a standard 1 ⅛ steerer tube. This includes many modern road, or mountain bikes.
  • Is it strong? Yes, This type of expansion plug system is common for steerer tube and headset assemblies. We have opted for a longer 50mm knurled plug for the extra security and stiffness. Most headset plugs are around 30mm. If security is still an concern, the extender epoxy bonded into the steerer for a more permanent solution.
  • Can you make the extension longer than 18mm? In theory yes it is possible to make them longer, however, for safety reasons we have set the maximum height at 18mm. We suggest you have at least half of your stem clamping around your original steerer tube. 
  • The extender is too large in diameter to fit inside my steerer tube. Every steerer tube can be have different internal dimensions - especially carbon ones where the internal dimensions are variable. We have designed the extender to have a tighter tolerance fit into most steerer tubes than your standard headset expansion plug for safety and security. Prior to purchasing, measure the inside diameter of your steerer tube. If it measures any smaller than 22.50mm, you may need to sand some material out. This intersection zone between the steerer tube and expender is only 3mm deep, so not very much material will need to be removed from the inner edge of your steerer tube. If in doubt, ask your local bike shop for assistance.
