So I'm getting back into biking after quite a few years of being a lazy *ss and need some advice from everybody. I'm deadset on a road bike and want to eventually work my way up to a full carbon frame bike but that's not important right now. I'm writing because I need advice on a new bike. All I had when I started riding were a couple of old schwinn road bikes from the early 90's and late 80's. Let's just they lacked the technology and abilities of today's bikes. I'm looking for used bikes on ebay, craigslist, etc but I'm not 100% sure what to look for and I'm really only familiar with two models that fit my price range. The trek 1.1. or 1.2 and the Giant Defy series. Are these good bikes that will last and handle a lot of riding? Are there other entry level bikes I should be looking for as well? I know I'd like a cannondale but I also know they tend to more expensive. Any input would be greatly appreciated. Thanks.
