it's the *plastic* ones that really need to be reproduced. They all got roached over the years. The metal ones last pretty well...you don't often see the steel pedals lacking their caps..it's the superleggeros that always lose their caps...
Someone should make the plastic ones, complete with the chrome finish, with some kind of clever comment printed on the circumference to mimic the look of the Campagnolo graphics. And when they're made, the threaded portion should be thicker! That little threaded rim always cracked off.
