Seen at the World Championship back in April, Serpent have released their new new super-light gearbox for the 966. The current Serpent gearbox system has been in use for a very long time, and the Serpent design has become the industry standard, with small revisions only. Stronger engines, research, racing and new insights have fueled the new gearbox design and the goal was to reduce inertia, fluent power transfer and increase reliability even further. The gears have been improved, made lighter, more durable with improved gear mesh. A new aluminium flange which seats the German made one-way bearing is lighter and the bearing is seated more in the inside of the flange for better balance. A new aluminium bell is stiffer and thicker to stand the force of the shoes better and the bearing is in the center to create even forces on the bearing. A new aluminium brake-pulley adapter features 3 steel pins, and also requires a new brake-disk which is also included, and a new mono-type side pulley/pulley-adapter.
