The Slot.it Step2 inline crown gears have new plastic materials, new revolutionary tooth shape, and new aluminum insert with anti-friction treatment. The Step 2 couples a grub screw with the self-centering crown gear where the motor axle is inserted in a thread in the crown itself. The bronze insert excels at performance, while lightweight aluminum performs best in sprint races.
