Derrick Smithwrote a review of Deity Components Copperhead Stem on April 12, 2018
Familiarity: I've put it through the wringer
Stems don't get much attention....until now. The stem is a critical component that often gets overlooked but not when you're rocking the Deity Copperhead. Aside from being absolutely gorgeous and a machining marvel, it performs just as well as a looks. Lightweight, super stiff, and a clamping design that holds carbon bars without friction paste and a super low torque on the faceplate bolts. The death of a carbon bar is over torqued bolts and not a worry with this stem, it's designed so well you don't need to get crazy tightening. I have the 50mm orange (talk about flashy!) that I love so much, I installed the 35mm platinum on my other bike.
