I mean, jeezus, did you think that the first time I rode a bicycle was six months ago? And some shop took advantage of my noobishness and sold me some clipless pedals and said I would be on the Tour in no time?
I started riding a bike when I was 7. I didn't use any foot retention until I was 27. I loved it. It made offroad riding easier, it made on-road riding easier. I really don't understand why I'm supposed to regress to plain pedals.
My commuter still has plain platforms. But, I don't bother using it for anything further than a few miles. If I want to, I can put some of my clipless pedals on it and take it for a long ride.
