The derailleurs are Atlus, which is Shimano's lowest component group in the MTB range and a surprising choice for a bike in this price bracket. I suspect a lot of the cost is being funnled into the disc brakes.

It's really a mish-mash of components. Shimano derailleurs, Microshift shifters, SRAM crankset. I'm sure it's a nice bike if your priorities line up with where the cash is going in the components.
