I recently purchased a new set of rims with Dura Ace 7850 hubs and there is a intermittent sporadic loud clicking noise when coasting. I never owned Shimano hubs previously, so I am not sure if this is normal. It is definitely the hubs since I removed the tire and cassette and the noise was still present. Is this normal or could there be a damaged bearing? I am a bit hesitant to bring them to my LBS, since I purchased them online and that retailer is on the other side of the country.
