Happy Stem 31.8mm



What's with the name? It's a simple all-silver polished threadless stem with a 45 degree angle to keep your back and wallet happy. It's perfect for touring or dirt drops like our Dajia Far Bar.

Four-bolt face plate. For 31.8mm bars and 1-1/8" (28.6mm) forks. 45-degree rise; at least 37mm of steerer is required. The design of the stem eliminates the need for a stem cap. Longer compression bolt is included. This stem will not work with the threadless stem adapter and is not to be used with carbon steerer tubes.


  • Handlebar Clamp: 31.8mm
  • Steerer Clamp: 1-1/8"
  • Steerer required: 37mm
  • Angle: +45deg
  • Weight: 203g (90mm size)
  • MTB-tested

We do offer a shim for 1" threadless forks.

Lil lift in style

I wanted a more upright riding position like a lot of people. I’m not a fan of the clunky look of adjustable stems or the combination with a stem riser. So I found this to be an elegant solution that made my back and my eyes very happy!

Having had Klunker bars for a minute, the happy stem klunker combo brought my hands up to a super comfy position and turned my old stumpjumper into what feels like a badass bmx bike/beach cruiser/city ripper. 10/10, just wish I couldve gotten the black one.

Happy Stem Indeed

This stem is exactly what was needed to make my back and wrists happy by raising my VO Tourist handlebars to a level that allows an upright riding position.

This is so much more comfortable for my 59 year old back.

Happy Stem Review

Excellent quality, reasonably light, and great price. And, I’ve come to appreciate its unique design from an aesthetic perspective.
