My comments is mostly on the fat front I rode for 2 years, 1 ride on the 29er front last Sunday. The Jones rides beautifully, balanced on the legs in a very different posture on the bike. The other standout characteristic is that it is very accomplished on technical sections, at least by my Dutch standards. Also note the long free length of 27,2mm seatpost, Titanium in both builds, means it does live up to the "compliant in the vertical" design idea.
And I am very happy with the 29er front change, makes it more agile and nimble, with better acceleration.
Enjoy!!
