I'm upgrading my geared rain bike, and I'm thinking of swapping the clip-strap pedals onto it from my fix, and getting some clipless pedals and mtb shoes for said fix. I went to a bike shop today (the one on 79th & 3rd in NYC), prepared to drop some cash if all felt right. The guy was helpful in explaining the difference in float, spd vs sidi vs eggbeaters. Only problem was that they didn't have any way for me to try them out before I bough them. I've never ridden clipless, nor do I know the difference in feel between a floading pedal and one that doesn't float. I dont want to buy something without trying it first--so are there any shops in NYC that have try-out shoes and pedals? Or is this unreasonable? Does one have to drop the money, THEN decide if you like them? Seems crazy, because you have to lock yourself in to a specific cleat system...
