I will be repacking the hubs later this year as a yearly maintenance issue and am just curious if the increase in cost is paid for in performance gains.
I assume the performance increase will be very low maybe .5 to 1 watt and the weight decrease would be negligible.
This may be the biggest hype fostered on bikers. They won't save you any measurable difference.
For our use good quality bronze bushings would be fine.
Ceramic bearings are designed for very high speed and heat like a turbocharger.
Bike wheels spin at 340rpm at 30mph.
