Wheel aligning methods?

[Banditbandit]

I use string. Easy as.

I've never figured out how to make sure that is accurate.

Quick look will tell if alignment is good.

Yeah - I have used the eye-o-meter for many years with no issues. (And not checking against the marks on the swing-arm .. that's never worked for me. I lie down at the back of the bike and check the alignment down the bike.)

With regard to eye-o-meter, strings or lasers etc each to their own I guess and whatever you are happy and works for you is good.
For a miserly $20 I thought its a good bit of kit.

Last time I used the eye-o-meter as I was miles away from home and needed to tighten a loose chain ('twas banging and rattling). The following week the bike was booked in for something at the shop - and I asked them to check the wheel alignment as well. They said it was "spot on". I am happy with that ...
