Wheel rim/brake surface damage?! Wtf?!
Can anybody help me identify what has caused this to my rear wheel? Similar on both sides. Only just noticed it the other night whilst cleaning.
Is it simply damage from brake blocks? Have since taken them off and and scrubbed them. The pattern of dots just seems odd. As opposed to a long scratch.
The dots are bits of damage to rim... as far as I can tell. Couldn't be chemical damage could it, from a ph 7 bio cleaner?!
Any suggestions appreciated.
