I stumbled across All-To Bike gearboxes from South Korea this morning while reading about Pinion's latest updates. (Pinion has finally gotten electronic triggers and brifters sorted!)
Anyways, This guy is trying to make lower cost gearboxes utilizing die-cast molding and several other lower cost alternative means of producing the parts compared to Pinion. I think I spied an anticipated cost of about 1/3rd of what Pinion charges. He's been very open about the development showing parts diagrams, assembly and current as well as proposed manufacturing methods.
