The Good: Great dampening, good adjustability, buttery smooooth action
The Bad: Could be stiffer, seals wear out quickly
This fork is incredible! Very linear feel through the first 2/3 of travel with a nice progressive ramp at the end of the stroke. This makes for a very supple feel from small bumps up through bigger hits into the upper-mid stroke while retaining good bottom out resistance at the end. The same fork settings that feel supportive yet supple on an XC hammerfest maintains it's composure on 6' stepdowns and 4' hucks-to-flat. This is the first 29er fork that I have ridden that can claim those traits.
The fork is very easy to tune to your liking with a low speed compression adjustment to take out the out-of-saddle fork bobbing, and a fully adjustable lock-out (which I never use) and rebound. Initially I wasdisappointed at the lack of an adjustable high speed compression circuit on $900+ fork but after spending a full riding season with the fork I realized that I never once missed it. Fox nailed the HSC for my riding style and terrain. I wouldn't change it if I could.
The fork does have a bit of fore-aft flex but far less than the RS Revelation 140. I think that this is a product of producing a 140mm 29er fork and still trying to keep the weight respectable. Side to side, there is little to no noticeable movement. The flex has also saved my ass on a few occasions. For example, when I slammed into the backside of a double on a DS course at race pace. Without the flex, I would have had a hell of a time staying on the bike and the fork might have snapped without a bit of give. Sometimes ultimate stiffness isn't always the best.
This fork likes attention. I am looking at about 2.5 month intervals for seal changes with riding 3 times a week, average. Pretty frequent but a relatively painless process and the fork feels sooo nice when it's fresh.
Summary- Damn expensive boinger but the only one I would use on a 5" 29er for aggressive trail riding and light AM use. Very, very impressed.
