Bottom Bracket Rotor Bb Press Fit 4124 Steel Bearings Black

' >UBB System

Covering all bottom brackets
It's easy to understand what the UBB means: it fits everything. BB1 BSA and SABB BSA for 24mm shaft. And BSA 30 for 30 mm shaft.
Universal Bottom Brackets are a concept that adapts and works for all bottom bracket standards and thus definitively eliminates the problem of complicated compatibility between bottom brackets and cranks. There is always a UBB crank to fit your bike, regardless of its bottom bracket type. Not only that, you will almost always find an unexpected solution in UBB30 for non-30mm frames!
End your headaches once and for all

• UBB30 cranks are 100% compatible with BSA (68 & 73), ITA, BB86, BBB89, BB92, BB30, BB386 EVO and BBRight frames (except BB90 and BB94).
• UBB24 cranks are 100% compatible with BSA (68 and 73), ITA, BB86, 89, 90, 92, 94, BB30 and BBRight frames (BB386 EVO not requested).

The comprehensive design concept used in the UBB30 and UBB24 systems resolves confusion over incompatibilities between crank and bottom bracket standards.

Here you have the compatibility table.
