I finally went with Kojacks on my Circa 2.0 and now easily run out of gears. on any down hill. While I hate to give up my low gear I think I would like to make it about or almost 1 gear faster. I have a Nexus 8 spd with 36t front and 20t rear. Im thinking about changing the rear to 18 or 19 but not sure how to figure out the ratio change.
Any mathematicians here??
