This is a nice write but I find something like this totally un nesasary . Why go to all the bother when all you have to do is just loosen the axil nut and move the cams to adjust the chain. Why do you want to have to turn the whole axil just to tighten the chain? As far not needing a 22mm wrench goes I carry a lot of tools with me so one more small wrench really doesn't matter. Nice explanation on how you did this though.
