Im 6’2″ and have a 21 inch one. Fits well with a very short stem and wide bars.
The short stays do mean its quick off the mark and the sizing works well for getting the power down and through the rear wheel, no matter how steep the climb. I would say this is an unsung trait of the frame, it climbs very well, lots rightly say its fast, and will accelerate away when allowed to. The slack head on the 29er makes for a very confident high speed ride.
I find the stand over just on my tolerence with the 21″, and an uppy downy post is essential for me to throw the bike around and get it off the ground, which took some time to getting used to. This is my compromise though I feel to have a very comfortable bike on long days out.
