I am also interested in the Fantom 27.5+ with the X9 components, just wondering if you are still happy with your purchase and if anybody else on this forum has had any experience with this bike or the X7, would really like to hear your comments. You did not mention your height when going with the large frame, I'm 5-8" and the BD sizing chart says a 16" frame for my height, do you think they are pretty accurate on their sizing because that does seem a bit small to me?
