Clipless pedals (usually known as SPDs) are really easy to use and once you get used to them (takes about one day) you will wonder how you ever did without them before. The downside is that you will need to buy shoes that clip into them, although these are available in numerous 'casual' designs. Shimano do an amazingly cheap set of SPDs for aout ?15 on eBay. I have used a pair on my commuter for about 6 months and they are almost as good a my ?80 set! Mr Asset saw a femaile rider slip off her wet plastic pedals with her wet rubber soled shoes recently (are you on the forum?) as she climbed DKH going into town. She didn't hurt herself, and he prob freaked her a bit by recommending SPDs as they rode up the hill together, but guys, you know what the result of slipping off your pedal can be. Eyewatering. The very important thing is to have someone experienced (eg. the shop that sells you them) set the angle of the clip (called a cleat) in the sole. Get this wrong and you WILL knacker your knees. I had to stop riding for two years once, and was considering surgery before I realised the problem. They are particularly helpful as they allow you to pull up as well as push down, like toe-clips but without the faff of getting your foot in and out (or numb toes due to lack of circulation). Shimano SPD cleats come in two types: multi-release and single-release. I'd recommend the latter to a newbie, as you won't know the difference and your shoe cannot come out unless you want it to.
