Recently got a new single speed bike which I'm enjoying riding fixed, but still very much learning.
Is it normal for there to be a degree of eneven chain tension when turning the pedals? There are spots on each chainring revolution where the tension is tight making it difficult to adequate tension across the whole chainring. I think it is excessive, perhaps around 2-3cm difference in vertical chain movement between the low/high spots if I wiggle the chain up and down with my fingers.
It has a new Stronglight chainring but had the same issue with the previous chainring. Wondering if the spider might not be perfectly centered. Crankset is a spa TD2.
