Tolerance for chainwheel wobble?

If its a new BB the spindle shouldn't be bent... I doubt 1.5 mm will have much of an effect anyway

I tend to agree and hope that I am just being overly sensitive.

The original chain ring on my fixed had a 5mm side to side wobble and also went up and down. Not sure whether it was like that when I first received the bike from new. Proved to be a bugger trying to get the optimum chain tension. Later found out you could get the whole chain set including BB for £40 off ebay. Chain ring was made of foil. Fitted a Miche Primato Advanced chain set and, I didn't measure it but, it looked pretty accurate. Couldn't get a perfect chain line but will be trying an SRAM Omnium this weekend. I'd expect that to be within 1mm otherwise I'll be unhappy.

5 mm is a bit much on anything other than a beater, I would think. Looking at my situation from the bright side, at least there is no vertical wobble!
