Hey everyone! Thanks for all the replies! I've actually gotten pretty comfy on my bike. I asked about the stem issue at LBS, and the guy said he wouldn't change it out and I seem fine on the bike, so he suggested I ride it for a while and then decide. I did take it out for 10 miles (which I know isn't much) this past Saturday and loved it! I feel like the more I ride and pay attention to my posture the less issue I have. I did decide to invest in a pair of bike gloves cause my palms were getting a little sore. Yay for bikes!
