Your views, advice, opinions or general heckling please…
I changed my the XT cassette on my Pro II yesterday. The old one appeared to be secured good and tight when I took it off.
Unfortunately, on tightening the new one up – the lockring satisfyingly goes ka-thunk-ka-thunk-ka-thunk – it wobbles and rattles about on its own accord as if the lock ring weren’t even vaguely tight.
The only remedy I’ve found for this is to put one of the spare old sprockets on first, which seems to increase the effective width of the cassette and allow it, somehow, to be secured tightly.
What am I doing wrong? 😕
