ACROS bottom brackets differ from bottom brackets of our competitors in some ways. On the one hand, the material of the ball-bearings is different; we only use stainless steel, which is more expensive to produce but excels in a significantly higher durability. On the other hand, ACROS has been focusing on the use of angular contact ball-bearings for years. These are able to absorb axial and radial forces, which for example act when pedalling out of the saddle, a lot better than ordinary grooved ball-bearings. The bearing grease completes a good industrial ball-bearing, which is why we have developed a special high-performance grease in cooperation with a leading lubrication company, adapted to the requirements of bicycles. Our grease ensures a stable lubrication even at low speed and under high pressure. On top, it is highly water-repellent and effectively prevents leaching. This is what quality means to us, and when we talk to our customers, we often get the feedback that ACROS bottom brackets exceed the lifespan of a competing product three to four times.
