I replaced the originnal pulley wheels on my 12 speed Campy with these. They work perfectly as far as i can tell, but it's also true that I can't discern anything differences between them and the original Campy pulley wheels. Perhaps I am a shade faster but not enough to notice. But then, I'm in my 60's and just ride for fun. For me these are nice bike jewelry.
