I have a condor italia from around 2009 with a Campag Centaur groupset. I'm not as fit as i'd like to be so i'm finding hills a struggle and would like to fit a smaller inner chainring. The crankset I have is 50/39 with BCD of 135mm, I don't think I can fit a smaller inner chainring, so I would like to know what options I have to fit a new crankset. This isn't a valuable bike so ideally i'd be shopping at the budget end of the spectrum.
Alternatively, is there an option of swapping the 10 speed 12-28 cassette to something more like a 12-34?
