Smash the cistern
Just before Xmas I swapped my cassette over. It wasn't quite shifting right so today I took it off and put it back on again to make sure everything was aligned properly. While it was off I noticed big gouges on all the outer spokes on the drive side, behind where the cassette goes. What could be causing this? They look fresh. Surely it can't be the cassette as that sits a couple of mm out from the spokes, and anyway these gouges are within the radius of the largest sprocket, if you see what I mean.
What's caused it, should I be worried and am I going to need my rear wheel rebuilding?
