Familiarity: I've put it through the wringer
I've been mountain biking for 25 years and I didn't know a bike could be this much fun. This thing floats, climbs, pumps and is just a joy to ride. If any bike can make you feel like Danny McCaskill this is it.
The GX/XO1 Eagle offers a great range and the 50 tooth cog will allow you to climb virtually anything you can stick too. That said, this thing climbs so well that you'll find yourself standing up with 3-4 climbing cogs in reserve as you just pump through. If anything, you'll run out of gears on the other end of the spectrum and if the 50 tooth isn't used much a larger chainring may be perfect to gain a little on the top end.
The 2.6 tires are perfect in my book and coming even from 2.4s these feel like a motocross bike but without the brapbrap. I'm 5'7" and got the small and feel its a perfect fit. Seriously haven't had this much fun on a bike, like ever! Just throw down the cash and buy it!!
