I was just cleaning the chain and noticed the free hub/cassette wobbles a lot when freewheeling. I can't tell if it happens when under load 100%. To my eyes, it does look like it has a little wobble when pedalling (with the bike on a stand) and the chain 'clicks' (might be jumping a tad). Its a cheap wheel (Giant S-R) but its only done 80 miles.

Pretty much the same as this http://www.youtube.com/watch?v=lxbNvj10eZg

I've emailed the store where I got the bike but I'm just enquiring to see if its a serious problem. The store is an 80 mile round trip so don't really want to go back unless I completely have to.
Cheers
