CTD–that’s Foxese for ‘Climb, Trail and Descend’. It’s also a marked departure in the way that Fox creates forks and shocks that suck up bumps, but don’t bob and wallow annoyingly when you’re pedaling. On it’s face it’s a simpler, perhaps less tuneable, approach to tackling suspension. It is, without a doubt, the first time that Fox forks and shocks utilize the same compression damping systems.

Fox introduced their 34mm chassis to stiffen up longer legged 29er forks last year, but it’s now available in Float fixed travel and TALAS travel adjust versions in 26er (and 650b) forms. But who or what are these stiffer but significantly heavier forks for?
Workshop rig testing and swapping forks between runs shows the upsized chassis is a much stiffer, more feedback-rich fork overall than Fox’s 32, and more rigid than the best 32mm forks in terms of front-back and sideways flex.
In fact, while a much longer negative air spring means good sensitivity over small stuff, the structural stiffness makes it less comfortable and arm-pump prone than the 32 chassis. While fork offset is similar to the 32, the 160mm stroke (it can be dropped to 150mm) tips the head back and raises the bottom bracket – we had to fit a shorter eye to eye shock to compensate.
The Fox RP23 has pretty much become the benchmark shock for all-mountain riding and thanks to leaps forward in technology is only looking to get better. The Factory Series RP23 that you see here has all of the latest goodies that Fox has to offer – slick Kashima coat, Boost Valve compression damping and the neat little ‘Adaptive Logic’ ProPedal lever.
Shockingly smart rear suspension!
FOX launched some new electronic bits to complement their 2013 Climb and Descend suspension modes. Get the scoop. Continue Reading →
