Fitting a 30mm spindle into a "BB92" ("BB86" in road applications) shell does not leave much room for the bearings--a challenge that has limited the use of BB30 cranks in such applications.  By making outer race of these bearings into the "cup" and adding a second row of ball bearings, previous limitations have been overcome.  The result is a strong, smooth, and corrosion resistant bottom bracket.  The races and balls are 440C Stainless Steel.  

Please note that this adapter bottom bracket is designed for use with BB92 bottom bracket shells with a press-fit ID of 41mm.  Since BB92 bottom bracket shells are 92mm wide, you must use a BB30 crankset with a long enough spindle, such as the Rotor 3D+ crankset.  For reference:
 
3D+ MTB "Double" (2 chain rings): 115mm overall spindle length
3D+ MTB "Triple" (3 chain rings): 123mm overall spindle length
 
 
KNOWN COMPATIBLE CRANKS:
 
 --Rotor 3D+ crank sets
--e13 MTB crank sets
--Race Face Next SL crank sets
--BB386EVO cranks (on BB86 frames)
