Technical Q&A with Lennard Zinn – The demands of ceramics
Are ceramics that delicate?
Dear Lennard,
In your article on ceramic bearings in the recent VeloNews Buyers Guide I got the impression that these things were not only smooth but durable as well. As a result, I ordered a ceramic SRAM bottom bracket with the Red crankset on my new bike.
To say the least, I was surprised when I read the SRAM maintenance instructions that came with it and saw the recommendation that one should disassemble and lube the bearings after every 100 hours of use and immediately after riding in the rain or wet.
