Is it possible to repair a bent steel bike frame? It is a racing bike that has been vandalized and whose frame is bent in several places.
Steel is one of the most workable materials in nature; it can be welded, bent, and straightened, so technically repair is possible, except in extreme cases.
That said, however, the cost-effectiveness of this type of repair must be assessed, bearing in mind that the market value of a steel frame is not high. If the damage is severe, and this seems to be the case, given that the frame in question is bent in several places, repairing it will probably not be cost-effective.
At this point, however, the owner's personal assessment comes into play, as high sentimental value may justify even a costly repair.
