Converting a Campy Victory crank set to a triple

[MennoX]

It has been done. does anyone know the detaills? I have 35, 42, 53 teeth chain rings.

What bottom bracket would need to go with this?

I have acomplete campy Victory groupo, front and rear deraillers, etc on a Univega Ital Sport bike from the 1980's

It has a S-bottom bracket that I know nothing about and would like to convert to Campy.

See my reply to your other post. To convert to a triple Victory crank with an English bottom bracket, you will need a 112mm bottom bracket, asymmetric (2mm offset on the drive side).

www.biketoolsetc.com has triple chainring bolt sets (intended to hold all 3 rings at the same time). you can also buy from them an inner chainring bolt set (10 pieces), 5 bolts which you discard, and 5 crucial spacers which presumably would make your conversion complete. Total cost for both sets is about $10.

Are there any other sources for chainring bolts and spacers to make a victory or triomphe crankset into a triple ?? One thing that would be really nice would be DEEP inner chainring nuts, so that you could use BREV CAMPAGNOLO bolts on your triple.

I am quite surprised that a 112 mm Bottom Bracket is what is needed. Regular nuovo record is 112 mm (R+3), and i had assumed that an extra 5 mm or so would be needed, e.g. a 117(R+6) mm bottom bracket spindle would be what is needed - same as a Nuovo Record Triple. Aren't Victory BB's and Nuovo Record BB's compatible? I thought the idea behind Victory was to leverage some Nuovo record components (print spares) for a few more years ...

He sells triple conversion chainrings where the middle ring has the mounts for the inner ring built in. He lists these in 144 BCD, which I believe fit your Victory cranks.

Victory (and Triomphe) cranksets use the rather unusual 116 bcd. These rings are unique. Luckily, wwcyclery (on ebay) and http://www.bicycleclassics.com/ both offer replacement rings, in particular, 35T and 36T inner rings. This is where I got the inner rings for my 2 triple cranksets.
