something off a stock road bike. i have a set of allez pedals on my bike now. half plastic and half metal, plastic clips and nylon straps. lighter than the mks tracks, alloy clips, and leather straps, plus i don't feel bad if i clip the edges when turning to hard.

they can usually be had for free or very little money at your LBS, mine are off my own allez but i have a couple other pairs of brand new ones laying around i got from guys who installed clipless pedals when they bought their bikes.
