The ACROS A-BB30R Ceramic
bottom bracket features the established high-end ceramic bearing and seal technologies from ACROS.
Precisely manufactured angular contact ceramic bearings form the heart of the A-BB30R and offer the smoothest spinning characteristics for a long time. ACROS Ceramic Hybrid Bearings are made of stainless steel bearing rings and ceramic balls. The result of this combination is an increase of the durability and the technical performance. The right sealing technology is equally important as the highest quality bearings when it comes to high-end components. For the A-BB30R 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 BB30R version fits BB30 frames (thread-less bottom bracket shell with an inner diameter of 42 mm).
