you always help spddemon, how much of a difference will aluminum rims make?

 

SpDdEmOn is typically right on the money.

Aluminum rims will give your bike a bit more zip.. you will feel like you have more torque. In the big picture, you will not be able to tell on top speed as the rotational mass does little in hindering the forward motion. It just takes longer to get to that top speed. The aluminum rims will let you get there faster and will also let you stop much faster (remember, the faster you go, the longer it takes to slow down. Most people forget this part.)

Hope this helps.
