Marshal SR71 Blackbird Supersonic Carbon BMX Frame x forks

French BMX brand Marshal Racing enters the carbon race frame market with their SR71 Blackbird Supersonic! The frame is inspired by the legendary speed and aerodynamics of the SR-71 Blackbird spy plane. It features Marshal’s patented dropout system which features 6 holes spaced 8mm apart and incorporating a crescent shape. This feature give the SR71 the ability to offers ultra-precise rear wheel adjustment. Marshal also created their new generation horizontal tension chain tensioner as part of the dropout system. I need to add this frame to my dropout list.

Thanks to our aluminum 7075 reinforcement integrated inside the dropout, the crescent-shaped holes, and our big base junction between the bottom bracket and seat tube, the SR71-BLACKBIRD offers unmatched rigidity for optimal power transfer. To top it off, the choice of renowned Toray 700 and 1000 carbon fibers is a testament to our commitment to providing an exceptional frame for the most demanding riders. ~Marshal Racing
