Do you have a steel frame bike that was run into a brick wall? MSU Bikes has a tool designed and made after the Park Tools classic tool by a very skilled machinist that we’re able to use to salvage some frames that others might scrap.  Bent forks can be straightened by a very skilled and experienced mechanic with the right tools (assuming the fork is made of steel) but are best replaced.  We don’t currently have such fork straightening tools but stock lots of forks and can order most anything we don’t have.  If you have a steel bike (sorry, aluminum frames are not repairable once bent) with a bent frame bring it on by and we’ll give you a free estimate.  Click here or the pics to see more examples.  This longer article/ discussion about the original Park Tool HTS-1 will give you a LOT more info. about what we can do with this tool for a bent steel frame.

Here’s a couple videos of a repair in progress.  The first one I took while our mechanics were starting the straightening:  |  After straightening:
