The original splined tubes that support the footrests are often (usually) bent....The bike only has to be dropped once to do that....However, bent tubes that have a good spline can be quite easily straightened and re used....Tap a piece of 1/2" diameter bar through the tube (it will usually go in with a little persuasion) and then straighten the tube using a flypress or similar...Once straightened remove the bar and check the fit of the footrest bar...Light application of a round file, reamer or half inch drill will complete the job if required....They can be straightened cold...
I've done many like this and used them again....Ian
