not sure you can take a road bike on the tube at all
BUT, you can get a cross train from kings cross (st prancras) to stratford... it takes 7 minutes and is a regular train so you should be able to take your bike and your stuff on there...
that'll least get you out to east without having to go on the tube
then it's not too far from stratford to canning town (two stops on the jubilee) - even if you didnt have your bike this would be the much much quickest way to do your journey
