Special Dr.Pulley rollers - 8 rollers 25x16

They are mounted on the original variator or similar ones.
Due to the material they are made of, they last twice as long as the original ones and their operation makes sense since they work by sliding and do not wear out, nor do they wear out the aluminium of the variator.
Their shape allows the belt to go down a bit more improving acceleration and when the variator opens, the ramp plate rises over the roller gaining speed.
By adjusting the ideal weight, we can improve the entire curve.
