Taper is the same, but current bottom brackets have symmetrically mounted axles (same amount sticking out both left and right sides), where older BBs are asymmetrical - chain-line may not work too well mixing crank from one generation with BB from another. Check your BB for symmetry/asym.

Also the spindle width itself may be quite different...current Chorus is 102mm & Veloce is 111mm, IIR-apart from symmetry issues

Standard cups and bearings?

If it is an late 80's early 90's fixed/adjustable cup set up it should work fine. It is a symetrical axle and 109mm wide. I am using this bottom bracket with a Centaur crank (111mm) and have not had a single problem with shifting or the overall workings of the setup.

Is the taper the same? Any other issues? It will be going on an 85 cannondale R300.

what about a Victory crank?

this prob doesn't help but I have a newish Veloce cartridge BB mated to an early 90s old-style Chorus crank on my FG, no problems
