If it is the smallest cog only, then the stiff link hypothesis has a point in its favor, as the stiff link will be most obvious on the smallest cog, which has the tightest curvature.
You can generally buy a small cog for your cassette if it turns out to be worn. Seems unlikely, because most people don't ride many miles on the smallest cog...unless they're also riding in one of the smaller chainrings. This "cross-chaining" practice prematurely wears cogs, rings, and chains and should be avoided. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
