Message: >Hi, >I recently purchased a set of used MTB wheels for a song. The intended purpose was to have a set of back-ups and put a slick on the rear one for the indoor trainer. The rear appears to be true and in good shape with one exception; the #6 cog is loose! #'s 1-5 are pinned together and of course #7 is against the lock ring. I have disassembled this thing and can find no reason for this loose-ness. There is a spacer between the #6 and #5 cogs but it seems to be in good shape. The hub is an LX and the cogset is Hyperglide C. Anyone have any thoughts? >Thanks in advance. <<<< the spacer between 5 and 6 should be maybe 1mm or so with indents around it's outer edge to index with the rivets securing 1 thru 5 ?? Sometimes a Compact casette cassette gets put on a non compact hub which causes the whole assembly to be a bit loose when lockring is tightened.There is a 1mm spacer that goes on the hub before the cogs to fix this. Do you also have other lockrings with shallower threaded portion As sometimes lockring bottoms out before things get tight,although the aforementioned 1mm spacer takes care fo this. Am assuming no-one has jacked with-cog spacers as in previous post...
