To remove vertical dropouts from a steel frame and replace with track ones.
People are saying it will cost £75, £100 or £120 pounds! Come on it cant be that difficult it must be possible do get it done cheaper.
If you want it done nicely then it takes 2-3 hours to make some nice dropouts, cut off the old ones, remove the paint and weld the new ones on straight, so £75 doesn’t seam too bad. I did mine for free, but they aint too pretty lol.
