Sugino CBBF-103 bottom bracket
$ 54.99
Sealed-cartridge square taper bottom bracket with a 103mm JIS spindle, designed specifically for use with Sugino RD2 and RD4 Mighty Comp cranksets.
The blue 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.
