A few days ago someone in one of my biking communities wrote asking just what, exactly, was up with clipless pedals, should he get some, and how does he keep from crashing after he does? The blizzard of responses was quite informative, the experience even moreso.
Glossary: LBS: Local Bike Shop. Clipless pedals: devices that allow you to mechanically attach your foot to the pedal of the bike. Toe clips: baskets integrated into regular pedals that allow you to pull up and push down.
I went biking with my friend Joshua last weekend with him on my old Cypress. I think it was the first time he'd ever ridden with toe clips, and it took him so long to pull out of them at stops I just knew he was going down once or twice. I kept thinking, "boy, you'd be something to watch in a set of clipless!"
