There's something to be said for those that come before us. Explorers, scouts, reconnaissance.  Leading the way, clearing the path and reporting back valuable beta. 

We celebrate the explorers and present to you the original intrepid explorers of land and space unknown. Astrochimp.

Carry him (or her) along on your ride and know you have the spirit of the explorers before on your side.

Fast and easy installation of your boring factory headset cap is now a breeze with this Shapeshifter headset cap. Designed to fit most modern bicycles and installed in under 2 minutes. Everyone needs a little more custom in their life and this is the easiest, best way to customize your bicycle--making it uniquely your own.

Here's the kicker! There's no hole in the center! That's right. No hole.  We're calling it the Shapeshifter and we're positive it's going to upgrade your stoke to level 11! Just install the Shapeshifter subassembly, tighten it down and pop your new cap on top. (still less than a 2-minute install.) When you're ready for a different experience on the bicycle, just pop it off and install something else. 

This is a new form factor for bicycle headset caps we're crazy about. No more hole in the center. The flat top cap design conceals the stem bolt for a custom-finished look. Toolless removal allows for fast swaps. Compatibility with the majority of modern bicycles means you should be good to go.

I thought the bike caps were all sweet! I got the Bigfoot, shut up legs, and the Astro monkey. Everything fit on my bikes. The astromonkey was sweet but I am nervous about the o ring being the only support for the topper. Haven’t put it on riding yet. Overall, I am happy with them and we will see if I lose the top monkey when out on the trails. Stoked to put them on my bikes and switch them around.
