7 tooth Avids
I installed a 3" track last year, and used Avid 7 tooth drivers. Works well, and the added traction is a plus. Also installed a C3 syncrodrive late in the season, tried both the stock 2.33 ratio and the 2.42 ratio. With the 7 tooth drivers, I decided to use the stock 2.33 ratio, as the 2.42 in conjunction was a bit low for my tastes.
