I have a Velocity Deep V wheelset whcih I've absolutely love with a Ritchey WCS hub in the rear and a Nuke Titanium hub in the front. I bought these off ebay and have put about 1500 miles on them and assume there were at least another thousand on them when I bought them. I'm now noticing a noise from the wheel that sounds as if the brakes are rubbing against the rims against one specific area of rotation however the noise seems to actually be coming from the hub. Is this what it sounds like when a hub is going or is this something else? If the hub does in deed need to be replaced could I bike shop do it easily enough if I buy a new hub? If this is in fact the hub could this cause any resistance?
