    Dirty Flea Rear Hub/Cassette Issue

    I have a brand set of wheels with a Sun Ringle Dirty Flea hub on the rear. Since they came with the new bike they had the stupid plastic dork disc behind the cassette. I was able to get the lockring off, but the cassette would not slide off like all my the wheels have. Any ideas what the problem could be?

    The cassette has probably dug into the aluminum freehub body. Take a second chain whip and rotate the smaller cogs counter clockwise while holding the larger cogs with the other whip. What cassette do you have on there. I'd recomend an XT or Sram 990 to prevent the problem.

    It's a Sram 970. I don't see how the freehub could already be damaged, the bike has only been ridden for a half an hour. Unless something happened at the shop.

    Nothing in the shop could do what 30 minutes of riding can in this case.

    The trouble with common sense is it is no longer common

    It's not really damaged in the sense that it won't work anymore. It just makes it harder to get the cassette off. If you reinstall the same cassette, it will work fine.

    Hardened steel vs. Alloy = steel wins. As stated above you've probably got a small amount ot notching occuring on your freehub body. The dual chain whip trick works great.

    I tried taking the cassette off before I rode it.

    The bike was test ridden before you bought it.

    So should I ride it and just not worry about damaging it further or should I do something about it?

    Well I was able to take off the cassette and there was a small piece of the freehub body that was to be sheared off. It was only on the edge of the freehub body. It was only the smallest cog that was stuck.
