Rated 5 out of 5 by 2BeFree This bottom bracket is well suited for the 30 millimeter diameter crank axle.
I was pleasantly surprised how easy I was able to install this product. There is minimal preparatory work before installing. This product is of great quality for its price. I enjoy the qualities of ceramic bearings in terms of its edge in hardness and durability. Ceramic bearings are very durable (will not deform, flat-spot, or crack) and minimize the chance failure caused by heat that is naturally generate by friction. An added bonus is the claim that ceramic bearings will clean the bearing race with use, making it faster as time goes by! Here is to wishful thinking :-)
