Hello,
In the past few years, especially recently, there have been far more no-name mountain bike frames hitting the market, mostly from China. I know that there have been many long discussions debating the quality of knockoff carbon frames, but would there be any issues with using a knockoff aluminium frame? Knockoff aluminium frames are basically what you would find on a mid-range big box bike, and I've never heard of anyone breaking a big box aluminium frame under normal conditions.

Does anyone have any experience with these cheaper aluminium frames?

Thanks,
