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 aluminium; the lightweight extender means you no longer have to purchase a new fork for your frameset.

FAQ

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 a concern, the extender can be 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 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 us - we can aid with installation.
