>Rating: 5


I've used it several times
True to size

Very easy to install - only issue I had was it was like a millimeter shorter than my old stem - had to add a 2 mm spacer - very light


Ridiculously Light - Awesome color

This masterpiece stem is exactly what I was hoping to get. The color is identical to the one shown here and the weight is exceptionally light.

Thing of Beauty

I've put it through the wringer

The Deity Copperhead stems are fantastic, the anodization and the milling are top-notch, they are available in the most common sizes and they add a bit of flair to any bike they are installed on. The super-short stack height keeps everything nice and low, but also offers a rider the opportunity to run this stem a little higher on the steerer tube than other stems. I run a K-Edge Garmin mount on top of my Copperhead stem, and in order for the mount to clear the stem, you need about 15mm of spacers. Not a big deal, just something to note since the bar clamp area is a little taller than the steerer clamping area. These stems are plenty stiff too, especially in the 35mm clamp. I love Deity components, I love the story behind the company and the overall philosophy, so yeah, I am a bit of a fanboy, but they do it well and they do it right. You cannot go wrong and would never be let down by the Copperhead stem.


what fender are you running here?

Pretty sure it’s the mudrug


What mm stem is recommended for a hard tail for trail riding? Is the industry nine 30mm too short? Still a beginner, any info would be awesome, thanks!
