Deity Copperhead 31.8 Stem

Inspired by the sleek and deadly lines of a Copperhead snake, the sweeping centre channels of the Copperhead stem wrap around the entire stem to minimize material while delivering the strongest steerer mount stem on the market.

​Our goal with the Copperhead 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 just wouldn't give up. After millions of cycles on both stress and impact testing this stem stubbornly refused to give an inch.

Deity is renowned for our focus on durability and the confidence we instil in our riders and customers. Our dedication to the symmetry between strength and weight is showcased in the perfect balance of style and function found in the Copperhead stem. Available in 35mm and 50mm lengths to get your cockpit perfectly set up.
