so, i finally got my 2010 se lager. i dig it so far, except for one thing: my bum hurts. this is the first time ive been on a bike in like 5 years, and im commuting 20 miles round trip to work. im thinking my discomfort will go away, but im not sure. im thinking about getting a new saddle, but the one i have looks too damned good with the bike. any advice? also, im in chicago which is notoriously hilly (yes that is a joke) and im running 48/17 SS. do you al think that maybe going steeper would be bad for my legs this early in the game? i was thinking 52/16, is that too steep for a noob?
