OUTBOARD BOTTOM BRACKETS
1st Generation Stainless Steel
We still offer our 1st Generation Stainless Steel Outboard Bottom Bracket (OBB) Cups for integrated spindle and crank systems for the following threading: Italian, Raleigh Super Corsa, French, Swiss, Chater Lea, and in 68, 73, 83 and 100mm spacing.
A threadless (press fit) OBB cup set is available for those that wish to convert older Klein frames that used the pressed-in 6003 bearing bottom bracket shells. Other frames that use a press fit system with 6003 bearings can utilize this threadless OBB as well.
All of our OBB cups come with our Standard 6805 bearings which have a full contact seal and a 100% fill with our Phil Waterproof Grease. You can also order your OBB cups with our low drag Carbonyte bearings. Our Carbonyte bearings have different internal specifications, use a low drag seal and our full synthetic Carbonyte grease. To learn more about our bearings please visit our Bearings section.
Our 1st Generation Stainless Steel Outboard Bottom Bracket comes with (1) 2.5 mm spacer that matches the silver finish of your cup (No color substitutions allowed).
Please note: We do not offer spacers for Stainless Steel OBBs in Italian, Chater Lea and Press Fit threading.
