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.

Nice Shirt, but not "Wrinkle Free."
Color: Blue, Size: Large, Color: Blue, Size: Large
I like the weight, feel and fit of the shirt, however it is NOT "Wrinkle Free." I put the shirt through the wash to see if that might fix the issue, but it's still wrinkled and I plan to return it. (Perhaps - if I ironed it - it would stay wrinkle free after that, but I have a closet full of truly wrinkle free shirts and pulling out the iron simply feels like too much effort.)
