Happens in the carbon fiber bike industry quite a bit as well. I’m not talking about knock-offs (which are also rampant and can be very dangerous), but “open-mold” bike frames which are designed and engineered by the factory staff, and sold to brands needing to get to market quickly. The quality of some of the produced frames can be very high, and are even favored by big US brands needing to fill a category. The Ibis Hakkalugi and Silk Road frames for example were open-mold products, built to Ibis’ engineering spec.
