I recently moved from a standard 16t sprocket on my Langster to a DA 15t, tightened it on but the lockring wouldn't tighten, had a closer look and saw the 15t was wider than my original 16t, I thought i'd stripped the thread of the hub or lockring, but I took the sprocket off and the lockring tightens fine, anybody have any idea what could be wrong?
I'm thinking of filing/milling down the sprocket to see if that'll fix it but thought i'd ask on here before doing anything permanent.
If I did strip it, is it more likely that the thread on the hub is buggered or that on the lockring? I was told that it'll most likely be the hub but surely the lockrings are manufactured to be weaker in the case of this happening as they're easier to replace.
