I think that's what the "top hat adapter" is, I guess you move your caliper out with some adapter thing too. Check the forum sponsors ad's at the bottom of the page.. Or someone will be along with a link shortly.
I am short on funds too, but was put off by the thought of having useless items left over after I get it done properly (shift kit) so I have opted for the delay.. I hate to be missing out on summer riding but I can't use one gear anyway, too noisy, I must be stealthhy.
