I just got my Shimano XT MT8000 1x11 groupset delivered to me yesterday. Mine was a tad better deal than that of Merlin Cycles. US$450 (converted from PhP) offers the same package but includes a pair of rotors. 32T paired with 180mm rotors and 34T with 160mm rotors (both center lock). Local overnight shipping was around US$12. My shipping cost also includes an additional order of a Narrow-wide 38T chainring. However, I'm not sure if they do international orders.
