The two sides of the BB screw together reducing the chances of bearing misalignment which can cause premature wear to the bearings.
Multiple carefully designed grooves are formed on the outer surface of the bottom bracket cup and therefore split the surface where the cup contacts the frame bore. This allows slight material deformation and makes the BB more tolerant to frame bore dimension variation. These patented grooves also store grease making the BB even less prone to creaking.
