i have a racing bike with all shimano tiagra and i was thinking of either upgrading the shimano to 105 or ultegra or mixing some shimano with some campagnolo (like veloce, centuer or maybe athena)
but i don't know if it will fit probably and i don't have a lot to spend so i cant just change the whole thing. PLEASE HELP!!!
