I upgraded my De Rosa’s brake calipers from a 43-year-old design (Campagnolo Super Record) to a 17-year-old design (Campagnolo Chorus). The “new” calipers (the eBay seller called them “vintage”) are dual-pivots with Campagnolo and Chorus imprinted on the brake arms. I used lined housings and stainless steel cables so in all, the stopping power feels like a significant upgrade over the Super Record calipers I was using. The new calipers seem to work OK with the mid-80’s C-Record levers although the quick releases on the levers to open up the calipers for wheel changes are a little inadequate because I’m using a 25mm wide rear tire.
