I have a mid-2000’s Centaur group. I wanted to order Kool Stop brake pads but I am a bit confused by the offerings. There is a Kool Stop “Super Record Campi 2011” model which says it’s for Campy skeleton brakes but also retrofits post-2000 brakes. There is also a “Campi 2000” model which fits Campy year 2000 and up. Is there any difference between these pads?
