Love my RAT! I bought the RAT for it's height off the ground. Being a Senior I really have no need for the knobby treads and the rougher ride. I won't be going off road. RAT tires are 24x2.10's. Can some one recommend what to change to? I am also concerned that with a tire change I'll seldom get below gear 16. If I change tires I should probably change out front sprockets, correct? Is that possible?
