Hello lacticturkey and All,
I did a test some time back wrapping a string around the spindle of a SpeedPlay pedal with a weight attached to it and measured the time for the weight to unwind a measured amount of string while spinning the pedal.
I did the test after lubing the pedal with the approved SpeedPlay grease gun and grease.
Then repeated the test after flushing the grease and using a very low viscosity synthetic automotive engine oil.
The results led me to believe that the fractional Watt saved with superior lube was not 'worth the candle'.
Also notice that the friction values for various bottom bracket bearings are small and subject to the same magnitude of force as a pedal spindle. https://www.bikeradar.com/...-bracket-drag-39233/
"Ceramic bearing-equipped bottom brackets â€“ or hybrid
ceramics, to be more precise â€“ are generally much more expensive than their stainless steel cartridge-equipped brethren. Manufacturers claim that they're not only faster by virtue of generating less friction, but in some cases, also more durable.
Friction Facts' new jig isn't equipped to test durability but in terms of drag, the ceramic myth has been thoroughly debunked.
"Bottom Bracket efficiency is predominantly based on the design and the quality of materials used, not the material itself," Friction Facts principal Jason Smith wrote in his latest report. According to Smith's data, the difference in drag between the top steel model (0.32W) and the best ceramic model (0.29W) was just 0.03W â€“ virtually nothing.
Moreover, out of five manufacturers with comparable steel and hybrid ceramic models, three actually posted lower friction values for the steel models than for the otherwise identical ceramic ones." [emphasis added]
