Resources. For riders seeking the advantages that ceramic bearings offer, then, the willingness to service and maintain the bearings is an important factor to consider. Further to that, three of the comparable steel and ceramic bottom brackets posted lower friction values for the steel bearings. This difference between the Ceramic and Steel, with no further explanation, can lead to a quick, but inaccurate, conclusion that ceramic bearings generally exhibit less friction than steel bearings.

These properties are perfect for the industrial applications they were originally designed for, and would appear to translate to cycling as well. Through precision machining we can cut our cups slightly larger than others: we cut our PF30 cups to the upper tolerance of the Press Fit 30 standard and discard any cups that are larger and would potentially void a frame warranty. Ollie Gray of Hunt says the cost is a result of working with the best materials and the precise manufacturing process, but he does echo Brunand in encouraging riders to focus elsewhere before chasing any gains. Now, imagine how the bearings react to this situation with one sitting at one angle and the other at yet another angle and the crank spindle forced between them. They (ceramic bearings) do run with less friction, which offers a significant advantage in industrial applications running at 20,000 rpm. Without steel on steel contact, corrosive wear can only occur when contamination is allowed to reside within the bearings for a prolonged amount of time, he continues. (before you flame me, I said "most" and not "all", knowing that this is the internet, and internet failure statistics will hold.). Performance ceramic bearings have an enemy: grease. Also, while ceramic bearings do offer a weight saving (they can weigh 50 per cent less than steel bearings), the reduction in weight is almost completely negligible when viewed in the context of a whole bike. Because ceramic bearings were designed to operate in industrial machinery, they are designed to get their biggest gains in the RPM range that most industrial applications operate.
