Hi all. I've been perusing the neat custom frames of fellow list-members (some of which were made by listmembers -- how incestuous) and stumbled upon what seems a relatively uniform aspect of the frames built with Nervex prof lugs. In particular, none of them seemed to make use of the Nervex prof bottom bracket shell. I've also got a custom frame of my own and it doesn't use this bottom bracket shell either; instead it has what looks to be a modified Henry James bb shell. Why don't builders use that shell?
