Hi all,

I have a problem with my shimano hyperglide cassette, its on a cheap Alexrims DA22 I believe. I noticed a problem when coasting, I felt a clunking in the pedals, then took the wheel off the bike and determined it was the cassette that clunks about twice per revolution. It also wobbles ever so slightly on the axle/hub. Is there a cheap (read: free) and easy solution to this or will I have to take it apart, buy lube/and or clean it?
