What's the closest BSC match to a 1974 campy triple bottom bracket, in the phil wood product line ?? Phil Wood & company isn't sure. They say, "pick the closest traditional BB that isn't campagnolo specific. our adjustable cups should do the rest."

Supposedly, the stock spindle of the old campy triple was 117 mm. however, campy was a little bit lazy in printing catalogue #17, and they used the same diagrams for the 112 double BB's and 117 triple BB's. Needless to say, the offsets on the 117mm triple BB add up to 112 mm. (http://www.campyonly.com/history/1974/triples.pdf).

I know that campy used thicker cups & lockrings by maybe 1 mm, so maybe a campy triple bottom brack is actually 117 R+6 ( = 112 + 2 mm for lockrings + an extra offset of 3mm) In that case, is a phil wood 119 R+4 the preferred bottom bracket? That would produce these distances from centerline of BB shell :
                  left right phil wood : 57.5 61.5 campy 3x ?? 55.5 61.5 are these estimates correct???? ------------------------------------------------ Don-
      Your hunch sounds correct to me. Interesting thing about Campy Record/NR triple BB axles is that they were solid and came with "thin-non-rifled" cups. Esentially the GS model is the exact same as the NR model except for the mat vs shiney finish--I only mention this because the GS is vastly cheaper than the NR model and performs EXACTLY like the NR. But back to the Phil Wood issue. I would expect your 119mm Phil Wood to work with no noticeable difference from a stock Campy. Also, the vagerities you mention in the Campy literature, I have found also. In fact, the last time I had a Campy NR triple axle, I measured it to be 118mm!! What can I say, its the gospel truth. Good luck and let us know what you finally decide upon. cheers- Dave Anderson Cut Bank MT
