There is another thread describing a broken plate on which the wheel axle is fixed, which bridges the chain and saddle stay - that was for a steel frame wherein the plate is brazed.
I have this problem where the frame is aluminium, or at least some aluminium alloy. The bike is fairly ordinary, nothing flashy.
can one simply weld the ends together with a MIG, and is that a bike shop or a car garage?
Or must an entire piece for the ends of the stays replace the one there? That seems difficult in that it's not a plate that drops out.
I can't believe I have to replace the frame.
Thanks for any help!
