    Comments about Niner Jet 9 Frame 2011:

    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.

    Comments about Niner Jet 9 Frame 2011:

    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!

    Comments about Niner Jet 9 Frame 2011:

    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).
