What is the advantage, if any, of lock on grips?
How do you know if your pedals and or cleats on shoes are worn out? I ride time Atac pedals, not adjustable. The left one is looser (more float if that's the right term) than the right.
What chain ring do most of you use? I spend most of my time on the middle ring and only use maybe 4 gears on the back. I've got 27, help me unlock the potential.
