Copperhead 31.8mm Stem

Deity Components

Our goal with the all new COPPERHEAD steerer mounted stem was to design a lighter sidekick to our beloved Cavity Stem, but the results delivered a stronger, refined, and lighter super hero that we just could not break.  All our designs are tested to failure, but the COPPERHEAD refused to give up!

With the Copperhead 35mm model's reach, it is our answer to today’s longer top tube designs with a zero degree rise to keep your weight evenly distributed for peak performance.  Don’t get it confused…the Copperhead is stronger than the rest of the stems on the market, but it is also a featherweight fighter.
