High-performance TTX Flow DV shock with adjustable rebound and high-/low-speed compression damping for precise setup.
The latest TTX Flow DV shock brings targeted enhancements to help you push performance and enjoy the ride more. ⚙️
An all-new, highly efficient high-speed compression adjuster lets you adapt the setup to virtually any track condition, balancing traction, comfort, and chassis stability.
Built on a race-proven TTX system with dynamic valve (DV) technology, the shock delivers quicker response, more consistent damping, and a smoother roll over rough terrain for calmer corner entry.
Adjustable rebound plus high- and low-speed compression damping make fine-tuning straightforward, while a redesigned rebound needle and shaft jet improve control and bottoming resistance.
Easy spring changes, a wide range of optional springs, and the option to add a preload adjuster let you tailor the package to your riding preferences. 🏁
