The post Nuovo / Super Record stuff, Corsa Record, Chorus, Triomphe, Victory…
had the CPSC regs designed in to pass the tests.
There must have been some loophole though regarding the chainrings. (maybe they set up a bike with the chain in the big ring?)
Campagnolo did for a short time provide Raleigh with CPSC cranks with a chain guard, then those vanished.
Shimano also made some Dura-Ace cranks with a chain guard for a time.
We wondered about that for a time way back and never learned the answer.
When the regs first came out we were wondering if they would put chain guards on track bikes… and what about the brake?
It was quite unclear.
