Sugino CBBAL-103 bottom bracket

Sealed-cartridge square taper bottom bracket with a 103mm JIS cro-mo spindle and lightweight aluminum cups & center sleeve, designed specifically for use with Sugino RD2 and RD4 Mighty Comp cranksets.

 

ⓘ 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.
