I think you would be better off going with a cog pulley set up on the back ,or a larger crank pulley instead of smaller pulley than the Stillen one. If you go smaller than you are asking for belt slippage problems.

I believe that it is actually a 6 "rib" pulley as there are 6 "ribs" (7 channels). The pictures of the 6 rib pulleys on the 928 sight have the same number of ribs as the pulley on my desk which is 6. I could be wrong but I always thought that ribs referred to the raised ribs on the pulley and not the number of ribs on the belt.
