Drivetrain Friction Question
Quote | Reply
As I'm getting my bike all race ready, I notice that when I spin the cranks backwards with chain, it does not spin much more than 1-2 rotations.
Also it definitely does not do the cool Ceramic Speed ghost pedaling.

Question: is this something I should worry about? Or is the no load free spin nothing compared to actual race wattage friction?


Shimano bottom bracket, very smooth.

Freshly waxed chain
Cleaned DuraAce pulleys

Pay attention to how fast that wheel is spinning. They really get it going and then post videos about "how smooth the drive train is". It's a marketing gimmick.
