As ive got that exact problem now when i got the bike a little over 12 months ago i had both the rims and hubs powder coated and put the discs back on. Now the discs are toast the metal under the coating has turned to powder so the disc wont run true.You can file the powder coating off the disc lugs easily enough - I know 'cos my front hub was poweder coated when my front wheel was re-built and its fine.
That wheel may not be complete toast yet - you'll need to take the tyre off to be sure, but to be honest, mine was just like that on the outside and it was a right horror show inside - scary in fact! But, dont start to shell out loads of cash just yet - get the tyre and tube and rim tape off and be sure first...........
Oh no never ever powdercoat the disc mounting surface, make sure they mask that , or remove the coating before fitting discHi, I know that a lot of people get their hubs powder coated as have I, but when I was getting Hagons to rebuild the SFX wheels (all of the spokes were bent), they said that it isn't a good idea to powder coat as the thickness can throw discs out of line?I am a total numpty about such things so I can only quote Hagons. A good thing about Hagons is that you can speak to the main wheel builder direct, if you have any queries.:thumbup:
