Really enjoying this bike. Climbs great. I'm coming off an 09 Nomad which also climbed great but the improvement is noticeable. It's more jittery on the descents of course but still fast and fun. I would describe it as nimble. The 140 Talas is a great fit.
I'm 6'1'' and picked up a large, fits well. The Float RL was a bit stiff out of the box but with some new air it felt better after the first ride.
I'm running 2.35's and mud clearance isn't even remotely an issue. There's about 2.5 inches of room. The MRP MiniG2 SL Chain Guide went on effortlessly and makes practically no noise. Headsets can be confusing to purchase but for a tapered one, this worked great http://www.hucknroll.com/chris-king-inset-mixed-tapered-headset-with-griplock
I live in Hawaii and still received free shipping. It was on my doorstep in 4 business days. Hucknroll kicks ass... Couldn't be happier.
