Hi! I'm new to bicycling, and I think I need a new seatpost. I'm riding an old Cannondale Criterium (fixed her up and everything), and that it is mad uncomfortable. I got a new seat and bike shorts, which help a lot, but I intend to take it for rides that are upwards of 100+ miles. After doing some googling, I found that a new seatpost might help ease my discomfort over bumpier roads. Do you guys have any particular suggestions?
