I have broken 3 of those weak Sunrace cassette hub bodies, on two different hubs. Same failure on all of them: The body cracks and splits at the pivot point of one of the pawls, where the material is very thin. Then it locks up and becomes a fixed gear hub, so to speak. If you stop pedaling you may destroy the derailer as well. I don't know if they have improved. I hear they work well for some riders, but I recommend avoiding it, for any heavy and/or strong/"aggressive" rider.

By the way, I had the occasional pedal to ground strike in turns. I swapped out the standard red suspension elastomer with the harder green one. That turned out to be a better fit for me, and could be for you as well. Especially if you ride with luggage.
