So it appears that my non drive side rear dropout isn't flat. So depending on my chain length my wheel alignment goes from being ok to being a complete mess.
heres some images to illustrate whats going on:
Starting off pretty flat, happy days...
...Oh, that doesn't seem right.... that's a lot of light.
... still all over the place here...
... ok right at the back.
for good measure heres a snap of the drive side. all ok on this side:
I commute to work daily on the bike, currently running with the axle right near the front of the dropouts. All seems OK, but I would be much happier if i could have it seated further back. I'm unsure whether to:
a) leave it the hell alone, its working OK
b) maybe approach a frame builder to see if anything can be done to fix it. Does anybody have experience of anything like this? Maybe some material could be welded on and then machined until flat again?
c) put a big washer between the wheel nut and the outer surface of the dropout to span the recessed bit? This doesn't sound sensible, but maybe somebody has some experience either way.
finally heres an image of my bike for "context":
grateful of your thoughts. thanks. josh.
