When buying a road bike frame many points need to be taken into consideration. Firstly budget, as the range in price is great you need to decide what you are willing to pay and that will help you narrow down the kind of frame. As frames are made differently by many manufacturers it is advised that you try one for size to make sure it works for your riding position. Lastly the weight of the bike is an important factor, carbon bikes are light and strong but start at higher prices, aluminum frames are good for beginners and occasional riders, however performance riders will want something a little better.
