Swedish suspension maker Öhlins is overhauling their lightweight TTX Air mountain bike shock platform, dividing it into two. Now with the option for either single chamber TTX1Air or dual air chamber TTX2Air layouts, mountain bikers can better tune their air spring curve to get the most out of their trail, all-mountain, enduro, and even eMTB bikes.
Öhlins TTXAir shocks get single or dual air option
Designed to deliver a new level of rear wheel grip and suspension control to a wider range of mountain bikes, two versions of the light TTXAir air shock give riders more opportunity for customization. Both the new single-air TTX1Air and the carryover dual-air TTX2Air (originally called simply TTXAir) shocks share the same core Twin Tube TTX damper technology as Ohlins’ gravity suspension. But with lightweight air shock construction, plus the ease-of-tuning through varying internal pressures and adding/removing volume spacers, they were more suitable for a wider range of mountain bikes than the TTX coil.
The TTXAir was already fairly unique in its compact dual-air chamber design that offered a wide range of progression adjustability, in addition to broad compression & rebound controls and many stroke & fitment options. But Ohlins figured they could expand the usability of the platform even more by adding an equally-adjustable single-air chamber version of the TTXAir.
Now the original dual-air TTXAir is renamed TTX2Air (get it?), and the new single-air shock is the TTX1Air.
What’s new in the single air TTX1Air?
Both shocks allow riders to tweak their internal air volume to pair with the various frame/linkage kinematics of a broad range of mountain bikes, with a bit of overlap between the two shocks.
The big difference in opting for the single-air TTX1Air is that it was designed for bikes with a more linear shock curve design that could benefit from a more progressive spring. Adding spacers has a bigger impact on the TTX1Air (orange, above), giving you the ability to provide more bottom out support for bikes with linear kinematics.
The dual-air TTX2Air on the other hand allows more fine adjustment of the shock’s progression (blue, above), better suited to bike with more progressive linkage ratios.
The slimmer TTX1Air design also means it will simply fit into more bikes, especially with a more compact end eye shaping to fit into tighter frame mount designs. Weighing in at 390g for a 190×45 shock, it’s also 61g lighter than the same size dual-air version.
TTX Air – Tech Details
Ohlins says both shocks retain their ‘signature’ TTX twin tube design damping technology, said to promise “extremely well balanced damping pressures” and “flawless damping without cavitation in all riding conditions”. The idea there is premium level rebound & compression damping control & adjustability, and reliable performance for all types of mountain biking disciplines.
Both shocks also now get higher the maximum air pressures, to better handle a wider range of riders and eMTB needs (TTX1Air max 300psi, TTX2Air max 325psi).
Both shocks feature 3-position, externally adjustable high speed compression, Climb mode and fine low speed compression & rebound adjustment. An Öhlins Performance Setup Guide will help potential buyers figure out which shock is best for their bike, and to optimize pressure & air volume setup for individual riding style.
Öhlins TTX1Air & TTX2Air – Pricing & availability
Both new Ohlins air shocks are available now in both Standard Metric 190/210/230mm & Metric Trunnion 165/185/205mm lengths, and in four adjustable strokes for each length. The all-new single-air TTX1Air retails for $720 / 645€, while the updated dual-air TTX2Air sells for $780 / 698€. Both include air spring volume spacers to dial in your setup, and hardware to adjust stroke.
Torkel Sintorn, General Manager MTB Öhlins Racing AB, said: “The expansion of our range to include the addition of the TTX1Air platform allows us to further build upon our solutions for our fast-growing list of OEM partners, offering a broader product portfolio to best suit the needs of the latest full-suspension platform designs.”
