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.

The best sunscreen I've ever used.
Style: SPF 50, Size: 1 Count (Pack of 1)
I recently switched over from chemical to mineral sunscreen, and I absolutely love this. I'm in Florida, and this sunscreen definitely stood up to the test of the Florida sun. Usually, no matter what sunscreen I use, and no matter how often I re-apply, I tend to get a little pink on my shoulders if I'm out all day, but this sunscreen kept me covered! Did well at the waterpark and beach as well, very happy and will be ordering more.

Don’t buy.
Style: SPF 50, Size: 1 Count (Pack of 1)
If you’re looking to dress up as a mime or ghost this is the sunscreen for you. It almost looks like white paint and as the cherry on top it doesn’t even spray evenly. For $20 a bottle you’d expect better quality but yet, here we are. Don’t buy it there are better options out there

Finally - the perfect sunscreen
Style: SPF 50, Size: 1 Count (Pack of 1)
I have become religious about using sunscreen - that's what one skin cancer scare will do to you. Since my laying out, baby oil/iodine days I have tried and tossed many sunsceens - facial sunscreens that melt, run and destroy my eyes, sunscreens that discolor my clothes. Enter Sun Bum Mineral - although I miss the sunscreen scent of summer, i will never go back. This brand delivers - rubs in easily, no ghostly cast (I am fair skinned), sprayers that actually spray, no killer eyes, protection that lasts thru sweat/swim. I am a true believer in this brand!

Great Protection w/out the White Cast
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
We had been using the ThinkBaby mineral sunscreen for years. I wanted to look for a similar alternative but with less white cast. I actually bought this on a whim because it had the fastest shipping at the time (needed it for an outdoor event we were going to). We are now three purchases deep with this product. In my opinion, I think it gives the same amount of sun protection as before without the white cast. It rubs in great. Non-greasy. Initially, the lack of added fragrance was a little off-putting because we were so used to the typical coconut or citrus scents, but we all got used to it. Definitely on my list of subscription purchases now. I wish it was available in a larger size.
