| Aug 7, 2016 at 16:46 | comment | added | Rider_X | I agree that bearing load is another factor (I didn't touch in my answer for the sake of brevity). I agree that non-drive side loads likely result in more even bearing loads (anecdote: I find drive side BB bearings always go first, despite being more protected from the elements). That said, I suspect the amount of realized friction and power loss is quite small, otherwise the moment BB went external manufacturers would have started spec'ing larger bearings on the drive side. Talk about an avenue for differential marketing. | |
