Quite a few brakes were lighter than campy. Galli Ti, Universal CX, Campy with OMAS bolts, Gran Compe 500 if you want to go Japanese. There were some others too. Centerpulls are totally wrong IMO, and I love Weinmann CP. Weinmann 500 sidepulls might have been used simply because they are light. They kind of suck as brakes though.

So what is the plan for these? Whenever I saw someone riding these BITD, they were covered in an assortment of weight weenie parts. Probably some were built up with drilliumed campy + a bolt kit. Early Dura Ace cranks were light. The rest of those parts make no sense.
