Overall Review:

So I've been on the bike a few times now, both wet and dry conditions. Its blown me away so far, really comfortable attack position, comfortable climbing position. First 29" bike and i'm loving it, corners well, jumps well, goes over everything. I do think its easier to ride than my 27.5 so that in my eyes is a good thing. Spec is really nice, the brakes did take a bit to bed in but their working really nice now. Rear shock is mint! smooth, doesn't blow through the travel and has a shed load of grip. Gx is good, i love a bit of Shimano but so far so good with the sram stuff. Wheels are nice and stiff. The tires are really impressing me, i was in the pissing rain today and no matter what root covered in slop in a weird direction i hit, it just kept a straight line. I was a bit concerned about the fork being a yari and not a lyric but it works really well and i wont be changing it. All in all this bike has blown me away. I felt like i was settling for a lower spec bike because im constantly reading reviews of carbon bikes with better components, but once i got it and rode it i knew i made the right decision.

I am so happy i went for this bike.

Nice one Trek
