53 teeth may exceed the derailler capacity both max rings and range

tiagra 4603 is listed as max ring of 50 and max range of 20. A 53 ring exceeds both of these.

OP should check exact model and specs.

Some times you can run out of spec fine and other times you get goofiness
Looking for more time to ride what I have
