Raleigh Twenty - Shabby Shopper

http://tsaleh.blogspot.co.uk/2010/01/review-velo-orange-grand-cru-threadless.html

When the bb is completely tightened to the point of bearings binding, the inner flange diameter is just below 68mm. However, the inner flange diameter has little relation to where the tool will actually tighten down in a given BB. Both flanges do not make it all the way to the bb shell. Due to the internally expanding design and variations in ID of the BB shell and roundness, the spacing between the flanges is usually a tiny bit to more than that wider than the BB shell. Alas, this means that there is virtually no way you can use this BB for a Raleigh twenty with a 76mm bottom bracket shell.

...but surely you could just get it faced/filed down a bit? 68-76= 8mm needed gone, surely 2mm eitherside will bring it within reach?

^all just guessing.
