The true possibilities of the 29er platform are finally coming to light now that forks like the 140mm travel Fox 34 Float 29 CTD FIT are available. This fork's oversized stanchions, redesigned lowers, and large amount of travel, along with Fox's new approach to fork tuning will let you open up a new realm of aggressive trail riding aboard a 29er. Fox forks have traditionally been featured packed, offering the ability to make any adjustments needed to tune the fork for any condition. The only problem was the difficulty for the average rider to make knowledgeable tweaks to the forks. High- and low-speed compression, lockout threshhold, preload, and rebound are all common adjustments, but, for the guy who wants to ride, and not relentlessly and aimlessly tune a fork, this can have a negative effect on performance and user experience.With CTD, one lever quickly and easily switches the fork's compression to ideal settings for the task at hand. The Climb setting adds plenty of low-speed compression to mitigate bobbing when standing on the pedals. Trail mode offers moderate low-speed compression to balance efficiency with optimum trail manners, it's also independently adjustable with three settings; soft, medium, and firm. Finally the Descend setting features the optimum high- and low-speed compression for plush action on steep and aggressive sections of trail.Another key feature to this new Fox is a redesigned spring curve for forks 130mm and above. There's now a more linear spring rate. This is achieved by using a longer negative spring and by reducing the air springAAAs compression ratio. The resulting curve gives these air forks a more coil-like feel, and it also uses more of its travel because the preload won't ramp up.The 2013 29er lowers are now nearly a half pound lighter than last year's comparable model.
