Aluminum sprocket vs steel and x or o ring chain and where could I get the best deal Steel crank. Supersprox rear if you want something that is relatively light and will last. If you want something that is light and relatively cheap, go aluminum rear; Driven or Rethal; I just buy whatever is the cheapest as long as they are not made by Vortex :rofl. Shop around for combo deals and compare prices on ebay also. What are you doing interms of gearing changes? Just wondering. Take are look at the sticky, I got some gearing info in there if you are interested. Have fun! --- _[View the full topic](https://forums.speedlife.net/t/520-kit/263996)._
