...on it without changing rim/hub? ok, so i bought a eastern medusa 25 tooth sprocket and put it on my gt dyno bazooka . it is like pedaling in 1st gear on a mountain bike! its terrible ! i know i need a 9 tooth for the rear sprocket now. it is currently set up for a 44 tooth front sprocket. but i dont have very much money. so is there any way i can change it to a 9 tooth in the back without getting a new tire or changing the hub? Thanks
