I'm looking in to buy my first road bike. I could go new but used seems right for me since I'm just starting. Mainly, I'm using it for commuting to work, ride distance for fitness and occasional hills Really noob questions but I don't want to make a regretting purchase. I found a seller selling a used 2010 Specialized Allez Sport for $850 equip with Shimano 105 gears, 30 miles old Gator Skins tires, DB4LW cyclometer (not sure if its good or not), and Inform Race Road Bontrager Shoes with attached cleats (could care less about the shoe but can I use the cleats on another shoe?). I'm not too sure what size the bike is, it says seat tube 52 cm and top tube 52.7 cm. I'm 5'6 ish to 5'7'' inseam 30'' slim build. Is this bike worth the price for it? If not, how much should I pay for it? Is the bike my size to get fit with? Any suggestions would help me a lot
