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.

Great pillow
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
The pillows feel great. Being able to remove portions of the interior allowed me and my wife to have a perfect fit. They do stay cool which seems to have helped with my restlessness.

As advertised for once! Lol
Color: Cooling Blue Cover, Size: Queen (Pack of 2), Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Queen size set of 2 pillows, I'm giving it 5stars first bc it has a good length and width!! If you've ever bought memory foam pillows before you know some are small!! Anyways after having it for 5nights, we loved that me and my huddy could adjust the Thickness amount we had in it to our needs, me needing a thick pillow and my husband needing a flatter one. So this was perfect for that. So far its nice to sleep on, stays cool, doesnt get hot. I would say its on the frimer side but softer the more foam you take out! Really its just good for the amount you spend!! Will it last 10years probably not but what does now a days. This is the only time my huddy n I bought the same pillow and both love it so I'm just still in shock it worked out so well!!

Adjustable pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
I love these because they don't go flat. You can pull out whatever you need to make them comfy for you. They come in two different layers. So you have that protective cover over the main case that holds the memory foam. They're amazing to sleep on. I have had these last for years without going flat. If you hate flat pillows this is the way to go. They are very easy to wash. You just have to separate layers. They are very thick, you can adjust the thickness. Everyone in my house has at least one. They are worth the money. I have never had to replace them, because they went flat.

Good pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Takes some getting used to but and the cooling doesn’t last very long in my opinion, but overall amazing comfy pillows. The materials are good and are washable. I mostly stopped waking up with a stiff neck and back.
