Honestly 가보나연_letsnayeon, looking at your riding position, I think your saddle is too high. Your legs at the bottom of the crank's travel are almost straight, but there are two reasons they should be less straight: first, you lose power because you generate nothing when it's straight, and second, you are prone to injuring your knees. Hope this helps.
@@gb_nayeon Actually, when I looked more closely and rewatched a few sections I started thinking I may have overstated my analysis and that it wasn't as bad as I first thought.
