Fastest in the world
The Navigator 101 is a one-of-a-kind. Its uniqueness is in the operative system patented by Butler. It is equipped with four rollers with a unique form, positioned on the two sides of the wheel in diametrically opposite positions.
With this system, the dismounting of the tyre with bead breakers is very simple ad natural: while the anterior bead breakers keep the bead in the drop centre, the posterior ones continue their course until the dismounting is complete.
