Innenlagermaße für Einpresslager (Tabelle)

At the 2011 Interbike show, Calvin Jones of Park Tool sighed as he described the proliferation of new bottom-bracket dimensions. I've covered all the ones here which I can find, and listed them in order of bottom-bracket shell internal bearing seat diameter so as to highlight compatibilities. Adapters for some -- ranging from the venerable Ashtabula system to new high-end systems -- allow use with a variety of spindles. Phil Wood makes adapters to fit most press-fit bottom brackets: "[i]f you have a press fit bottom bracket (Merlin, Klein, Fisher, Ritchey, Fat Chance) and need replacement parts, we have spindles and bearings that will work" -- see Phil Wood FAQ page on bottom brackets. Wheels Manufacturing makes a number of adapters between these systems, as does FSA. Also see compatibility information in the table below . -- John Allen.
