The weight of this gearbox, without the motors is 4.6 lbs. This is 1.1 lbs heavier than the AM Shifter.

We have made no effort to fabricate lightening holes or features in the gears or side plates. That would take machining time, which would add significant cost, driving the price way over $400.

Three main places that teams could reduce weight in this gearbox would be to replace the aluminum extrusion with spacers (about 0.7 lbs), lighten the final drive gear and the cluster gears (about 0.4 lbs), and put lightening features into the 2 side plates (about 0.4 lbs total). Using these 3 methods alone, 1.5 lbs could be reduced for each gearbox.

As we prepare documentation for this gearbox, I will make more detailed designs regarding how and where to lose weight.
