whats the reason why you need to use 56t...pls do tell me
I don’t think that’s relevant. The OP had been using a 56t, for reasons known to themselves (only chainring lying around?).
Now they obviously intend to use a smaller one, but have some concern over the potential damage to the frame.
The question is whether significant material has been removed?
