In order to even stay atop my bike and last an entire mountain pass (passo) in Italy, I'm going to have to change my crankset from a 53 x 39 to a 50 x 34. I thought I could get away by simply changing a chain ring. But that is not the case. I wasn't anticipating replacing the entire crankset, but apparently I have to fork out more $$ to do so.
So similar to Contador, I too will be in a 34 to do battle with the Stelvio. Just another one of the $acrifice$to make to ride in Italy.
