I am building an early/mid-80's cyclocross bike (Alan/Concorde with Italian BB threading) with mostly Super Record parts. It's going to have a single chainring up front with campagnolo cyclocross chainring guards.

Based on the attached image (from campagnolo #18 catalog) it looks like I need a spindle similar to what I have marked in red.



I am going to get a Phil Wood BB and I am not sure which is the best match. I am not sure which one from there product list will work best. First it looks like I need something with JIS taper since Super Record is per 1994 Campagnolo. It also seems the BRS16 is probably the closest to what I need. 116mm with a +5mm right side offset.

Any thoughts? Advice?

Thanks in advance.

sounds like you've got it figured out to me

I guess I was really just looking for confirmation before I drop $150 on a bottom bracket.

Thanks.

I think you've picked the right one, based on that chart. Seems like the extra length on the driveside is to allow for the chainguards either side of the ring.
I'm sort of annoyed with Phil's practice of labeling the taper choices as they do: I'd never say a pre-94 Campy crank uses a JIS taper spindle. I *think* I understand that Phil makes or made a "compromise" taper that's half-way between the *dimensions* of the JIS and "early ISO" as used by most all the European-made cranks (including Campy pre-94) as well as the Sugino Mighty series. This used to be call the Phil Wood Universal taper, cause outside of Phil's world, there's still a difference between JIS and "old ISO" dimensions.
Maybe I'm wrong about this, but it's what I recall I was told by many LBS as well as a Phil employee, back in ancient times. At any rate, I still love those Phil products and if you are in doubt, call them up and speak to a human there to confirm you're getting the right unit.
