Ive been riding atvs for 8 years now and I just completed my first bicycle build recently and am already modding it to my liking. my question is where do I go to find a 30-something tooth sprocket that fits #41 or 415 metric chain. my bike goes 35 mph with a 44 tooth but I cant keep up with traffic in a 35-40 mph zone and I am looking for a sprocket that would allow this. Thanks for any and all help folks!
