Roughness occurs in both chainrings (a little more notable in large, but that may be due to tension).
The roughness does seem to vary depending on the cog used on the cassette. eg it's worse in the 12/13/14/15 and seems to improve above that up to the 26 tooth cog.
Performance has 20% sale tomorrow. Would like to figure this out. Think I should get a new cassette?
