Product Information
Full details
The Deity Copperhead stem is engineered for aggressive mountain bikers ranging from Trail and All Mountain to Enduro and Downhill disciplines who prioritize steering precision and a stiff cockpit feel. Its primary benefit is a highly optimized strength-to-weight ratio achieved through precision CNC machining, though riders should note that the 35mm reach requires a specific riding style preference compared to longer stem options.

Setup, Compatibility & Care
To install the Deity Copperhead stem, ensure your steerer tube is clean and free of debris. Slide the stem onto the 1 1/8-inch steerer tube and tighten the side bolts incrementally to ensure even clamping pressure. Always use a torque wrench to prevent over-tightening. The stem is strictly compatible with 31.8mm diameter handlebars. For maintenance, periodically check all bolt hardware to ensure they remain at the manufacturer's recommended torque specifications, especially after heavy riding sessions in wet or dusty conditions.
