Hello everybody, I am new to this forum and to the sport. I bought myself a used bike which is almost perfect for me, apart for the crank which is too long for my knees.
I have an ultegra 9 speed 6503 52-42-30; I would like to change the crank with a DuraAce 9 7703 53-39-30.
Is it possible to make a straight swap? Or, since the chainrings are different do I have to change the front derailleur and the chain?
Thanks a lot for or help.
