The new DMR DefyDH Stem, made in response to demand from DMR’s sponsored riders and downhill teams, is engineered to accommodate all dual crown forks. Building on the trusted handlebar clamp design of the acclaimed Defy stem, this updated version elevates performance. It’s an ideal choice for downhill and bike park setups.

The DMR DefyDH Stem is the premium choice for downhill, race, bike park, freeride, dirt jump, and all-mountain builds featuring dual-crown fork setups. Made with precision CNC machining, it offers a secure top-close clamp and comes in 45mm or 50mm reach options with a 28mm crown rise. Its widened clamping area enhances handlebar stability, while the streamlined design complements modern mountain bike geometry. Engineered for reliable performance and rider confidence, the DefyDH Stem is essential for any gravity-oriented bike.

Like all DMR stems, the DefyDH is engineered for durability rather than ultralight weight, avoiding fragile bolts and flimsy construction common in many modern MTB stems. Built tough to withstand demanding use, the DefyDH stem delivers clear performance gains on bikes featuring a long front centre, slack head angle, and aggressive geometry. Install it once and ride with confidence.
