A pulley reviewed and corrected for a lighter alloy of 120 grams while increasing the grip for a recovery and more frank acceleration.
Here is the brand new pulley POLINI called SPEED EVOLUTION 3. This pulley is treated ceramic which allows it to have a much better grip so no loss in the transmission. In addition this pulley is lighter than 120 grams compared to the origin which is not negligible. 
After a long test, POLINI concluded that the roughness of the polish should be 3 microns. Clear this pulley will allow you a much better grip of your belt so a slower wear and a much better recovery curve exit and acceleration for example at the start stopped.It is advisable to accompany it with its corrector of torque also ceramic.
