I am getting a little preasure on my left shoulder blade when riding this bike. It was not made for me and I have no idea what the proper seating position is. My knees are slightly bent at the "bottom" of the stroke. My inseam is 32" the bike was built for a guy with 31" inseam. The boom is adjustable. Should i move it out an inch? It feels good except for that preasure on the left shoulder blade. I see some pics with what looks like foam tape on the seat does that help?
