Moving from old style pedals years ago, to when I took up cycling again more recently, I noticed a difference when oiling the bike, while doing maintenance.
After oiling an old style pedal, I would always flick it to see that it rotated more freely due to the new oil. It would do several rotations and take a few seconds to slow down. But doing the same with my newer clip-in pedals, they only do a few turns.
Is this due to the one-sided pedal (Shimano LOOK pedal design) having a weighted end? That is, does this pedal slow down more quickly after it is flipped, due to it's asymmetrical pedal weight distribution? Or, do people think there would inherently be more friction in such a pedal?
