The ACROS A-BB 30R1 bottom bracket features the established high-end bearing and seal technologies from ACROS.
Proven bearing and seal technology grant high longevity for ACROS inner bearings. The angular ball bearings ACROS uses take combined radial and axial loads, e.g. resulting from pedaling out of the saddel, better than grooved ball bearings.
A special bearing grease cares for a constant lubricating film at high loads and "low" rpm, works water repellent and offers great resistance against sluicing.
ACROS A-BB bottom brackets are compatible with Shimano Hollowtech II and Race Face X-Type cranksets featuring a 24mm spindle.
Included in delivery is a RTS tension screw (which might not fit a few cranks with differing threads).
