Formula Introduces the ‘Mod’ Rear Shock

Today Formula announced the release of a new coil sprung rear shock which has been years in the making. Interestingly, Formula has been able to integrate user swappable compression stacks just like they do with their MTB forks. Read on for the full press release…



The Mod is the first shock with CTS (Compression Tuning System) technology. We wanted to have the trademark of our forks on our first MTB shock.

Thanks to CTS technology, anyone will be able to tune the rear suspension quickly and easily. CTS means fine-tuning within everyone’s reach.

The Gold valve is designed for light riders or those who like the rear suspension to be softer than usual and super smooth.

The Orange valve is designed for more aggressive riders looking for more support at medium and high speeds without compromising small bump sensitivity.

The Green valve is suitable for heavier riders or those who have a very aggressive riding style and seek maximum support all the way through travel.

High Flow

The Mod was designed with the concept of High Flow in mind. The 30mm internal piston and the increased oil passages provide the Mod with unique characteristics.

Compression and rebound adjustments keep their settings unchanged even on long descents. All of this results in improved sensitivity, less friction, and excellent heat management. The High Flow design of the damping allows the Mod to be remarkably consistent in performance.


Inside the piggyback, the Mod has a large-volume bladder. This design has the purpose to drastically reduce friction compared to a traditional internal floating piston (IFP) system.

This allows us to minimize friction and inertia in the system and achieve an excellent sensitivity to small bumps.


People often believe that the bottom-out bumper is just an accessory, but this is not the case. The Mod’s bottom-out bumper has a motorcycle-derived design which allows optimal management of the last part of the travel.

Thanks to this bumper, you can use the stroke up to the last millimeter with a very smooth feeling, and without noisy bottom-outs.
