Can anyone recommend me a high quality 7 speed cassette. I have been carousing ebay and online retailers so I have an idea of whats out there. I recently purchased a sram 7 speed but was disappointed to find out the spacers are plastic. SunRace makes some that seem nice. And the shimano HG cassettes all seem to be branded acera. So Im skeptical as well.
I know 7 speed road parts are all ancient, but any input is appreciated.
