How many of you have caught the ceramic bug? I have a mild case myself. I popped for a HOPE bottom bracket with ceramic bearings and a set of ceramic RD jockeys, also a set of ceramic bearings in my tubular wheels. After some bad experience with a normal FSA bottom bracket I decided I wanted the ultimate in durability down there so I went for the HOPE. The jockey pulleys were just a bit of bling and the wheel bearings I got cheap from a local importer. The friction savings are real but small, the selling point for me was, as said, the durability. What kind of ceramic stuff are you running and or considering?
