    I received a tricycle frame, can it be repaired?

    I was given this frame by a fellow commuter at work. He had it replaced under warranty and was kind enough to pass it on to me.

    It has a crack in the bond between the frame and the tube that connects to the crank/boom tube.

    The material is 4130 steel.





    Assuming I can find a competent frame builder, is it fixable?

    I suspect it can be fixed, but if you do build up the bike and ride it I would recommend keeping it clean in that area so you can see if any of the booms have developed cracks. I gather that the cracked part is not shown in the second picture?

    Correct, the crack is at the base of the forward most tube in the second photo. Just wanted to include a better idea of the whole picture.
