Frame alignment advice for a newbie

[Viator]

Advice wanted for a newbie!
Recently purchased a fixed speed and whilst tensioning chain I noticed that the rear hub leaves slightly different gaps in the dropouts/lugs. To my untrained eye I think the frame is slighlty out of aligment. How can I tell for sure ie which bits do I measure?
Many thanks in advance.

I am not sure if I completely understand your message (me not Brittish). (Actually maybe I'd better say I am sure I do not completely understand it). But maybe you can do something with this trick. If you want to see if the forks of the frame need to be aligned.... Check while tightening the quick release if you can see any movement in the fork. If this is the case you have to align it using specializad Campa or Shimano tools. I would sugest to see a specialist bike shop for this.

Look at the distance between the chainstays and the rim, close to the BB. that will give a good indication whether the rear wheel is properly aligned or not. Or put the bike upside down and try to get a taut string to line up parallell with BOTH rims, as close to the hubs as you can without interference from the spokes. If the rear wheel is displaced axillary it can to some extent be adjusted with washers.

Yessss.... This will give you an indication if the WHEEL is aligned. It however won't give you an indication if the frame needs to be aligned. First of all because the wheel alignement can be changed using the wheel spanner bolts, secondly because at the point where the chainstays start any possible disalignment is too small to be visible at that point.

I would first check the dish of the wheel before you do any checks on frame alignment. Frame alignment should only be done by a competent frame shop.
