Hi all, I just put a deposit to order my Giant Defy 5. I'm pretty excited and can't wait to get it fitted and riding in about a week. Here's my first question, should I invest in shoes and clipless pedals or put my money towards something else? I will be mainly be using my bike for transportation to and from work, roughly 5 miles round trip with a nice hill towards work and mainly downhill coming home. If not pedals, shorts, gloves, computer? I've been mainly riding on a cheap department store knockoff road bike. Thanks again in advance for the help!
