I was just reading a thread about clipless pedals, and quite fankly I got lost. I am new to cycling and on my bike I have just regular old pedals. I have seen the ones that the shoes clip on to, and the ones with the toe cage thingamajigs, but I have no idea what I should be looking for. I understand that they greatly improve your riding, and I would love to upgrade to one system or the other. Which should I look at first? What brands? What is the price range for a decent pedal system? Many thanks in advance to you all, O Wise Ones!
