SKF Bottom Bracket JIS 121mm BSC

SKF Bottom Bracket JIS 121mm BSC.  Ideal for TA Cyclotourist double cranks.  SKF bottom brackets are better sealed than any modern bottom bracket we have ever seen.  Beautiful German craftsmanship and machining.  It is easy to understand the quality when you think of Leica cameras and BMW automobiles (if you are into the car thing).  Unlike the other "premium" bottom brackets out there, this one really can live up to its promise.
