Just was looking into AM hardtail 29ers, when I noticed that the Vassago Chupacabra has dropouts that you can switch to correct the geometry to a 120mm fork. Just wondering, what does that exactly, do to the geometry? and has anyone else tried it? Not much info on the Chupacabra online.

Also attracted to it's price (much less than the previous planned alternative, the Banshee Paradox, and with more tire clearance too) and it's low standover and long ETT.

Thoughts? (was thinking of running a 120mm ManiTower, short stem, 1x9 with chainguide system)
