I know this may have been asked before, but I want to get a good idea of which to do. On a fairly steep hill which combo would you use, 30/25 , 42/25 or 52/25 ? or should I be using a 23 or 21 instead?
I tried the first combo of 30/25 and it just burned me out "spinning like crazy" and going no where fast. I figure it may be best to just "Mash" em and get it over with than to sit there "spinning" and prolonging the agony.So there has to be formula to this and I want to know what you guys use as a combo to get up those steep hills. Thanks in advance
