DMR Sect Frame
Description
The original DMR Sect frame laid the foundations for a generation of dirt jump and street bikes. Constructed from a durable 4130 chromoly tubeset, it delivers the ideal balance of strength, resilience and low weight, making it perfectly suited to dirt jumps, pump tracks, skateparks and street riding. It is now available as a frame-only option here.
Designed around a 1⅛" straight head tube, this frame is compatible with 1⅛" straight steerer forks only, maintaining the proven geometry of the original Sect platform.
At the rear, a hydroformed chainstay yoke allow for an exceptionally short rear end, creating a responsive ride that makes manuals easier to lift, spins quicker to initiate and technical tricks feel more intuitive. It's a classic DMR dirt jump frame, built for riders who want to build up a bike that's tough, agile and ready to session all day.
