    Say, does anyone know if it is safe to spread the width of the rear drop-outs on the Hyper Cruiser, the steel frame, from 110mm to 135mm to replace the single speed coaster brake rear wheel with a 7 speed free wheel? I will use the bicycle for two to three thousand miles at speeds no greater than 30 mph. Thank you all for sharing your experiences,

    If its steel, you can safely spread the rear drops an inch..

    It’s fine. Make sure everything is straight or you’ll have issues with the axle tightening and possible bearing cup issues if loose ball type.

    Same kind of idea except I used a screw Jack and it worked perfectly still can have to barely pull the frame over the night but I don't mind doing that and it is straight and true still

    I've stretched all my frames. Caveman style. Stand on one side and pull up on the other. Flip it over and do it again to make it even. Stomp on it for fine adjust.
