1989 Doug Bradbury Manitou

Doug Bradbury started building innovative aluminum mountain bike frames in Manitou Springs, Colorado around 1985. Compared to his earliest bikes with very tight and steep geometry, this bike has a longer top tube and a slacker (67°) head tube angle. The wheelbase is also a couple of inches longer than comparable bikes at the time. Characteristic Bradbury features include the asymmetric 145mm rear axle spacing, 115mm front axle spacing, 90mm wide bottom bracket shell, seat stay mounted U-brake, and triple clamp fork.
