MEASUREMENT EXPLANATIONS:
Please try to get measurements to the nearest 1/8 inch or better. Frame dimensions are in order of usefulness, frame dimension & angles (10 though 12 ) are difficult to measure and not necessary to design your frame, but they are helpful if you can obtain them. CL is centerline. Measure centerline to centerline of the tubes BB is the bottom bracket |
