Deity's goal with the all new COPPERHEAD 31.8mm stem was to design a lighter sidekick to their beloved Cavity Stem, but the results delivered a stronger, refined, and lighter super hero. All their designs are tested to failure, but the COPPERHEAD refused to give up! After millions of cycles on both stress and impact testing this stem refused to give an inch. This stem is Deity's 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. Perfect for any application from Trail/ All Mtn/ Enduro/ DJ/ Slopestyle and even DH, this stem will take anything you have to offer and keep asking for more!
