A THINstem is ruggedness-certified and rides like a normal stem (but about 1.5" higher). But then, when you need a smaller bike, just fold your bars flat in seconds! It fits most forks, and we carry THINstems for two thicknesses of handlebars.

Maybe you have a really old bike, back from when a stem stuck down inside the bike. You can still install a THINstem, but you'll need another installation first.

First, you'll swap out your current Quill stem with an adaptor to get your bike into the modern "threadless stem" world.

These pedals feature a quick-release latch and lock; rely on them for everyday use, yet remove them in seconds for easier bike storage and carrying. We stock four different types, they are interchangeable, and they fit al cranks.

2. Folding THINstem.

Now on clearance: THINstem for vintage 1" handlebars.

Before handlebars bulged in the middle by design, there were the classic bars that stayed the same 1" thickness the whole way. Got a vintage bike? This THINstem is for you.

 Normally $70, but just $58 while supplies last. 

3 (Maybe). A Quill Stem Adapter.
