I have new (for me) 2008 Orbea Onix TDi with existing 50/34 front crankset. My shifter is 3 steps - to switch from 1st to 2nd I have to click twice. All parts are Campagnolo Mirage.
Climbing the hills on it for me is too hard - I'm 230lbs. I've just ordered a new 52/42/30 Campagnolo Mirage crankset. But I have a feeling that 30 teeth still won't be enough.
Can I replace the 30 tooth chainring with let's say 26 to make climbing easier? And if yes, which one would you recommend?
