The only difference between Record and Super Record was the brake levers. SR were drilled out, Record were not. Calipers were the same. The drilled SR levers were actually slightly heavier, due to a thicker gauge aluminum being used to compensate for the weakening of the holes. Most of the old timers here will remember this lore. The smart thing was to go with the regular Record. SR were purely for fashion.

IIRC originally SR were supposed to have Ti center bolts, but that never happened in production.

BTW is there any suitable modern replacement for the old 1.8mm campy brake cables? That was a big part of the feel of those brakes.

Oops. EDIT. I found a source myself a couple years ago. Haven't tried them. Old cables work fine. These claim to be 1.8mm but maybe they are just 1.6 with a coating.
