If you don't have them already get some padded shorts. I saw some at Dick's and Sports Authority for around $30-40, Canari brand. Unless you have loads of money, but people that buy OCR3's usually don't

Before I had them I thought someone was sucker punching me in the kidney. It was just the saddle racking me every so often.
jerseys have convenient back pockets.
the tight cycling clothing is something I completely overlooked. Once you wear it you will never want to wear a t-shirt and gym shorts again. I definitely had to work past some embarrassment when I first went out in skin tight clothes, but no one pointed and laughed. So it wasn't so bad.
