I can ride three loops of my moderately hilly ten mile trail in the middle chain ring and in the middle of my rear cog. Never change gears and don't really get any more or less tired because of it. The descents are faster than I care to go and there's never enough time to shift from a big chain
This is too hard for me to say. Basically I never shift. If you really wanna know why then I will gladly figure out what I'm trying to say at your request.
I managed to get a B in writing 1020 somehow!! Yay for me
Edit: What the heck I posted this twice.. ugh sorry
