Crazy Al Cayne
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
