They weren’t penned. In fact they had no locking nuts and came apart easily. I’m going to put on thread lock later today. There are no brand or other markings on the pedals or the hard slippery plastic blocks. Of course they have metric, #8 bolts. There is no play in the bearings and they spin really well. They cost $18.99 including shipping from America -Eagle - Cycles on eBay.
No reason someone couldn't do that using a vertical mold like @ifitsfreeitsforme uses for his grip manufacturing. There are several grades of semi rigid pvc that would be more than durable enough for blocks. Plus it's typically uv stable so no fading
The original blocks on these pedals were advertised as pvc but ridged as a brick. Anything flexable would be a big improvement. Its pretty bad when your foot shoots forward off the pedal.
There are hundreds of kinds of "pvc" though. Agreed if you could find a polymer that was durable, mildly flexible, and still maintained shape. Many marine grade pvc are like this. Like the flexible stuff they use for dock edging. Tough as nails and built to be outside but still flexes where it needs to
Someone with more know how than I have needs to start making these. I thought there were new ones available about 7 years ago but perhaps they were just old left over parts like mine. Now they appear to be fairly nonexistent, if that’s a possible description. Mine are really nice, made of rubber and never used. I have one more set.
I tried a pair of those once. Thought they would be cool on a black and red bike. One of them self destructed shortly after install.
