Next one is up hill.
Off course, next one is down hill.
I like narrow road. It's exciting and thrilling.
I think I need more heavier front gear, because now I can use 3 smaller rear gears with front bigger one. I can use some low gears. and I guess shorter crank length is better. because with longer cranks, the position of feets go up and down with wider distance. it brings unstable.
Any way, I had an adventure today !
Fine.
