I prefer a 52TX14T over a 45TX12T (same gear) as I believe less energy is lost in the chain/frame system.
Correct me if I'm wrong here; but if you are saying that friction = power lost, doesn't that mean that 45x12 is better than 52x14, because the chain makes contact with fewer teeth. Fewer contact points = less friction = less power losses?
