Awesome frame at a great price!
This frame is a great platform to begin a 29er build. I outfitted mine with Shimano XT drivetrain components and brakes, Easton handlebar and wheels, Thompson seatpost, Selle seat, Fox fork, Crank Brothers pedals, etc. and I love it! Bike rides and handles great and seems to just want to roll over obstacles unlike any 26er ever will. I had a Trek Fuel EX8 before this one and the Niner handles almost as good despite the bigger wheels. If you get this bike, or any Niner for that matter, don't forget the YAWYD headset cap!

PROS: Easy To Install, Durable, Easy To Build, Attractive Design, Good Handling

CONS: Heavy

BEST USES: Mountain Biking, Racing

Wow.
This is for the XL frame. I am 6'7" and around 210lbs with gear. A little heavier than the Niner EMD hardtail I had before, but at least as fast uphill and faster down. Much easier on my back on a 2hr + ride, exactly as I hoped. Easily switched over parts. Just what I was looking for - a good, fast, fun, sturdy XC bike - at a great price.

PROS: Attractive Design, Fast And Smooth Ride, Durable, Lightweight

Outstanding quality. Amazing.
I bought this frame not only because of several compelling reviews online but primarily because it was on sale. When the frame arrived I was floored by the beautiful craftsmanship. I haven't ridden it yet but I will update the review once I do. FYI... save yourself $20 by not purchasing a seat collar. One comes with the frame (contrary to the description).

PROS: Attractive Design, Sealed Bearing Pivots, Beautiful Welds

A joy to ride
I really love the frame so far. I only say that it is heavy because I am comparing it to the hard tale I replaced with this frame and the pricier carbon frames on the market today. Otherwise it's a great frame. I went to a 1 x 10 driveline and it works great on this frame.

Nice upgrade option
Got this frame a few months ago and living it! Was looking for a new frame after damaging my 29er hardtail, and found this frame at a great price that allowed me to upgrade to full suspension. My backside is so happy that I did. Nice ride, solid grounded feel and very responsive. Jenson rep Steve was also super helpful when I was picking up frame to get me set up with all the right parts for my frame swap. Very happy overall!

PROS: Good value, Attractive Design

Great deal for a bike of this quality
I had crushed my calcaneus (heel) bones 10 years ago and so I have major ankle issues. Recently, I built up a nice XC hardtail only to find that I just cant do hardtails for long rides due to my bad ankles. This frame was the answer. just enough squish to take the edge off but still climbs like a champ. I combined it with the Fox OE shock deal to get a frame-fork-headset and derailleur for less than most frames alone sell for. what a great deal. big time value. this bike just wants to accelerate. I'm loving it so far. only drawback is it is a little porky. I have not weighed my build but guessing around 26 lbs. not a big deal. I am hoping to log in some long rides on it. vary happy with it.

PROS: Attractive Design, Good value, Fast And Smooth Ride

CONS: A Little Heavy

BEST USES: Mountain Biking, Endurance Rides
