My front wheel makes a grinding noise and vibrates pretty bad when I spin it. There's no visible damage on the outside so I'm thinking the bearings are worn out (or possibly worse).
So I was wondering what size cone wrenches I need to open up the hub and what size the bearings are so that I can buy replacements if that's all that's wrong (hub may still be ok).
Also where does one buy good bearings? I'm in Canada (Vancouver).
