ok so I went on a 27 mile ride yesterday with a couple of friends. At the start I noticed a strange noise coming from the rear wheel when I was coasting. I looked at it tonight and it seemed to be coming from the bearing area. I took the wheel off, cleaned the bearing area and re lubricated. but it is still there. to me it sounds as if the bearing might be fried. its a sort of grinding noise as it free spins not the click click click that a rear wheel normally does as it turns. This wheel, like the bike, is only 4 months old. I am probably going to take it in to REI and get them to do something about it as the bike is still pretty new. Is it reasonable for me to expect the bearing/ wheel to last more than 4 months? Do you think my guess at the issue is accurate?
Looking for advice / comments etc.
Bit concerned as I have a 60 mile ride organised for Saturday
