I think it could be the saddle too. When I got my bike, the LBS switch my seat from a Jett to a Specialized Windie (very soft seat). Man, I was in pain within an hour. But yesterday, I switched it back to the Jett and I rode over 3 1/2 hours w/ no pain. My seat bone is a bit sore but the LBS said the seat will need about a week for it to "soften" a bit. I truly believe in a harder seat for a long ride now!
