"Don't waste your money on ceramic bearings." If we've discussed ceramics, you probably heard me say this. I've found that ceramics never last as long as a good steel bearing. We usually replace most cartridge bearings with Phil Wood & Co. bearings. With proper maintenance, they survive even in tough cyclocross conditions. ENVE Composites did some water spray testing, and they also found stainless bearings survive longer than ceramics.
