The ACROS A-BB Press Fit bottom bracket features the established high-end bearing and seal technologies from ACROS.
Precisely manufactured angular contact bearings made of stainless steel form the heart of the A-BB Press Fit and offer smooth spinning characteristics for a long time. The right sealing technology is equally important as the highest quality bearings when it comes to high-end components. For the A-BB Press Fit ACROS uses the R3 seals featuring a specially shaped sealing lip with steel-plate reinforcement to achieve the best possible properties. The slide-on seal is firmly seated, defining and guaranteeing optimized function with low friction.

ACROS A-BB bottom brackets are compatible with Shimano Hollowtech II and Race Face X-Type cranksets featuring a 24 mm spindle.
Included in delivery is a RTS tension screw (which might not fit a few cranks with differing threads).

The Press Fit version fits BB 86.5/89.5/92mm frames (thread-less bottom bracket shell with an inner diameter of 41 mm).
