What's your discomfort? Are you male or female? How are your bars positioned relative to your saddle (high/low)? How's your reach to your bars (long/short)? How about to the pedals, what do your legs look like at the bottom of the stroke? At the 3 o'clock position is your kneecap over the pedal spindle (no, KOPS is not required but it's a good place to start)?
