HASSNS DH Stem Dual Shoulder Specifications and Performance
Built for downhill and freeride environments, this dual shoulder design maximizes impact resistance at vulnerable connection points where handlebar tubes meet the stem body. The 31.8mm clamp diameter fits all modern DH and all-mountain handlebars while the reinforced shoulder construction handles repeated stress from big drops and aggressive terrain. Each HASSNS DH stem undergoes impact testing to verify durability standards exceed those required in professional downhill racing. The geometry concentrates material at high-stress zones while keeping overall weight minimal—approximately 160 grams for 60mm reach versions. Engineers designed the dual shoulder configuration to distribute lateral loads across a wider surface area, effectively reducing stem failure rates in extreme riding conditions.

I’ve had a similar one before, but from a different brand, and I really like it. I installed it open and used stainless steel screws, it turned out great.
