I have a 2007 Catrike 700 and my uncle has a 2006 Catrike Speed. We
went for a ride last week, and noticed going up a hill, that I was
working much harder up the hill than he was with his speed, and I was
in 1st gear all the way around, while he wasn't. . . However, going
down hills, I didn't max out and had several more gears that I could
utilize, while he was maxing out. We are looking for gearing
somewhere in the middle, so that I am able to 'spin' a bit more up the
hills, and he can really crank into the peddles down the hills.

Has anyone changed their gearing, and if so what would you recommend?
