Stops possible chain fall off I think, DH bikes used to have chain devices that weren't dissimiliar on the front chain ring.
I think it is a bit excessive, but When ragging the bike hard from the lights my chain tensioner gives it up sometime and you can feel the whole thing go slack, though ** crosses fingers ** the chain has not come off yet.
I prefer the kits with lots of little spacers because it makes it a piece of piss to get the chainline bang on.
