So I recently got a road bike as some of you may already know (made a post about it regarding another issue). Anyways I am bake to ask what my issue may be. Now I obviously am experiencing some lower back pain due to being use to riding a hybrid bike for 2 years. But my butt seems to hurt maybe only 20 minutes into the ride. I am fitted correctly but I have no idea why it is like this. Any advice would be helpful. Should I go back to my comfort seat? I am riding on average 40 miles per day. Thanks
