Poll doesn't mention DP's- clips on one side, flat on the other. I have Shimano's on two bikes. Makes it so you can have a dedicated ride- or just hop on.

I was pretty disdainful of them despite a friend badgering me a little to get some, although the idea of getting some "pull" as well as some "push' was attractive to the engineer side of my personality. Then I got the recumbent trike where being clipped is a real plus. I then got a set of DP's for the Sirrus, had my obligatory tumble and now am fine with them. Added them to my BD/Moto- my sister got me another set for Christmas. Once you get used to them it's like.... riding a bike. I wouldn't want them for just any bike though- They'll stay off my old stuff and the new 3-speed. Give yourself some room though- don't get in a dense clump of riders. You may not fall, but if someone in front you does you'll all go down like Humpty Dumpty...
