Sugino's CBB-SG75 is an exceptionally high-quality sealed cartridge bottom bracket with an aluminum body/cups and cro-mo 111mm spindle, for use on Sugino 75 and Grand Mighty square taper crank arms.

This spindle length & taper is also compatible with Suntour Superbe Pro, Dura Ace 7600 & Campagnolo Record Pista crank arms.

FYI: The white stuff on the threads is medium-strength thread locker, which prevents the cups from loosening over time, even when a thin layer of grease is used. Don't try to scrape it off, it's a good thing.
