Got a new mech hanger and still had problems, then found that the bashring is wobbly.
Basically, looking at it from above, I spin the cranks and can see the bashring and sprocket wobble from side to side. The cranks don't wobble and are straight and the bottom bracket is still fitted properly with no play. Any solutions/ideas?
They're Middleburn cranks and bash on a trialtech pro bottom bracket. I've taken the crank off and tightened the circly thing on the inside (I'm clearly no expert) and that's done nothing.
Thanks, really need this sorted before Radfest...
