Speaking of Made in the USA, Tree Bicycle Co‘s newest creation is as innovative as their splined sprockets. The Collet Stem is made of 7075 T6 aluminum and is designed around the clamping mechanism, a collet. How awesome is that? Need a better description?

“This Stem is designed with a collet on the headtube. When the bolts are tightened the top and bottom of the stem come closer together thus compressing the collet piece onto the fork. The bar adjust is separate from the headtube by loosening only the bolts in the front of the bar. “

Head to your local BMX shops and demand one of these today! So freaking rad.
