Well, I just got finished cleaning and regreasing two headsets between my four bikes. And now I'm sitting here (staying in from the 30 degree rainy weather and not looking forward to the ice coming tonight) wondering if I should repack the bearings on the hubs of my Barracuda Mk.I as well. Hubs are, as far as I know, low end Shimano or something else cheap but effective. (it's a 27" wheel, give me a break ) Purchased them new August of 05, and since have run probably about 1500mi on them. Only thing done to the wheels since purchase has been adjusting the hubs when new. They've been through one short rain shower, otherwise all dry condition riding.
