The new Double WAC feature on our famous WAC Corporal magnesium custom mountain bikes provides two speeds for Gates carbon belt drive users without any internally geared hubs, or shifters. It’s just like the Double/Double chain setup, but with a belt drive. Since the belts are wide, Paketa’s engineers had to redesign the rear chainstay yokes and dropouts to allow for clearance of tow belt sprockets. The Double WAC the smoothest, quietest, double double set up with this unique Gates Belt Drive sprocket combination. You’ll have to come to the NAHBS show to see how it really works.
