I wouldn't be surprised if "Dimension", "SunRace", "SunRun", or some of these other makers had contracts to make Shimano's down-market cassettes and freewheels, and Shimano is slowly handing over the market to them. I have absolutely no evidence to support that theory, but they are definitely stepping up to fill the void now that Shimano has stopped making HG50 cassettes in 7-speed. Too bad they're not making more of the tight "road" configurations, though...
