Acros A-BB Press Fit R1 bottom bracket

Angular contact ball bearings made of stainless steel and well-designed seals ensure durability with minimal maintenance in the acros Pressfit bottom bracket, allowing for more carefree time on the bike.

Bottom brackets should simply work. "Install and forget" is the motto of acros, and with this in mind, the acros Pressfit bottom bracket was developed. Since acros values inner quality above all, double-sealed angular contact ball bearings are used in the Pressfit bottom bracket. These industrial ball bearings made of stainless steel can better handle the forces that occur during pedaling compared to simple deep groove ball bearings. Additionally, the ball bearings are protected by a special dust cover against dirt and water. This also prevents contact between the crankshaft and the ball bearings, reliably eliminating the occurrence of creaking and squeaking noises for your worry-free experience on the roads, gravel paths, and trails of this world.
