[predator03]

Looking for some good advice from you experts. I'm still learning about this gearing stuff. I've already geared my Predator down to 13 teeth in the front. I ride in the rocky terrain of the Tennessee mountains. I would like to gear it down just a little bit more, it will help me climb the rocks. The thing is, I would also like to go up to a 22 inch tire in the rear. Does anyone have a suggestion for gearing. Is a 12 tooth available for the Predator? Or would 13/40 be a good combo?

Thanks for the help

Scott
