I have been looking for a 39 tooth in the rear and a 13 in the front. And i finally found both at the same place. Different brands though. www.nacsracing.com go to the online store. I would post a link...But i don't know how to make it so everyone can click on it.

I have a couple questions about quality and brands.

Is Sprocket Specialists a good brand?

Does anyone have Nac's Racing rear sprocket?

What Size chain would i have to get and what brand do you recomend?

Any info would be great.
