Carl, I have a Shimano bb on my Cypress. I believe it is a 105. I didn't specify the bb at the time, but they were putting on a 105 crankset, requiring a new bb so I assume they used a 105. My LBS didn't have to special order it. As far as I can see, the bb shell is a standard 70mm wide. I haven't measured the axle length, but I am sure it is one of the standard standard triple lengths.

D*Alex, I hope I can get the kind of mileage you have on your old Sugino on the old 105 on my Bianchi. I really like being able to pull it apart, clean it and repack it to keep it going. I just did it recently strictly because the bike had been sitting idle for many years. The bb actually had almost no mileage on it. Next time I will replace the bearings with the high grade ones just so I know for sure what it has. It may have good ones now, but I guess there is now way of knowing.
Regards,
Raymond
