• Hey guys, this issue is bogging my mind and I can't seem to fix it. There's a 7-speed RX100 hub, with its original cassette on the freehub. The locking is tightened maximally, but there's play on the cassette. The smallest cog casuses the issue somehow, the rest of the cassette doesn't even touch that one. So it's fully up in place, but there's just too much room on the freehub body and there's like 2 mm of play at least. Once again, this is a stock hub and its stock cassette. The small spacer between the 5th and 6th cog is present, so it should be perfect, but in reality it's not. I tried 2 different 11T cogs from random other cassettes I could find, and the issue is still the same. Does anyone have a clue how to proceed? Thanks!

  • Might not help but isn't there also usually a small spacer between the 6/7 speed? it wont be 2mm wide but other than that I'm not sure what else to say other than stick a spacer behind the whole cassette.
    Have you checked the hub is not the 8 speed version too?

  • Pic?

    1) Double check the smallest cog is fit correctly against the second smallest. It’s easy to overlook sometimes.

    2) Does the spacing between each cog look even? If not, where?

    3) Is there play in the freehub by itself?
