TTX1Air Trunnion Shock, 45 x 165mm

The Ohlins TTX1Air Trunnion Shock brings the precision and consistency of Ohlins’ TTX twin-tube technology to a lightweight, single-can design built for modern trail and enduro bikes. Designed around a compact single air chamber, the TTX1Air delivers a more progressive spring rate that offers improved mid-stroke support and bottom-out resistance without sacrificing small-bump sensitivity.

The Trunnion mount design allows the linkage to bolt directly to the sides of the cylinder head, keeping frame integration tight and responsive. With external rebound plus low- and high-speed compression adjustment, riders can fine-tune damping for climbs, descents, and everything in between. A climb mode helps minimize suspension movement when pedaling uphill, while a specific wiper seal and optimized air sleeve lubrication reduce friction for a smooth, controlled feel on every ride.

• TTX Twin Tube design delivers consistent damping performance across varied terrain
• Single air chamber provides a progressive spring rate with improved support and bottom-out control
• Trunnion mount offers compact fitment and a stiffer connection to the frame
• External adjusters for rebound and both low- and high-speed compression for precise setup
• Climb mode reduces suspension movement during pedaling for efficient climbing
• Extra bushing overlap improves side load management and durability
• Includes two air spring volume spacers (-2.5mm and -5mm) for fine-tuning travel and progression
• Optional spherical bearings available for widths up to 22mm to reduce friction under side loads

The Ohlins TTX1Air Trunnion Shock (45 x 165mm) is engineered for riders who demand efficient climbing, controlled descending, and long-term reliability from their rear suspension.
