That 65 mm width could just be a screw up, too much taken off faces during manufacturing, I have seen brand new unbuilt shells that approached that width. This is not uncommon.
In reality you should be able to use a 68 mm bb in it, realizing that it's only 1.5 mm per side, not that significant in the big scheme of things.. maybe during set up you might want to use a spacer (FW shim) under the fixed cup to fine tune chain line, but even that may not be necessary...

Greetings list members,
I have a new-to-me track bicycle that has a bottom bracket shell width of 65mm. A quick Googling reveals that this is a very uncommon size, but also that Campagnolo made a spindle for it: 65-P-120. I haven't measured the pitch of the threads.
Can anyone tell me more about this bottom bracket size? The frame is an early 70s Eisentraut. I suppose this is also a Want to Buy post.
Thank you.
