22T bell, 46tooth spur. IIRC, it's a 2.3:1 ratio...A little high, but I can work down. optimum should be ~2.0:1 or slightly less.

I'm using some hard shoes with added weight and .9 clutchsprings bent to be really light.. No wear as of yet, but I haven't had it on the dirt yet...I can see wear being an issue though....
