Formula MOD Coil Spring Rear Shock - 210x55mm - matte black

Formula MOD Coil Spring Rear Shock - 210x55mm - matte black


Formula MOD – Essential, modern

There is no point in trying to be someone else if you can be yourself. The Formula MOD is precisely that, an original way of imaging a shock. The MOD is packed with everything you expect from a coil shock: sensitivity, feeling, reliability; but there is also much more. Formula has integrated performance, ease of use and maximum tuning possibilities.

The MOD has an unconventional design that, thanks to the CTS technology, will allow every rider to fine-tune the rear suspension simply and effectively. The High Flow design of the damping allows for uncompromising reliability. Thanks to its large-volume bladder (LV), the MOD rear shock manages to have very low friction and excellent small bump compliance.

Someone said that today’s modernity will be tomorrow’s tradition. If you are trying to maximize the fun-factor on the Trail, and if thinking out of the box is something you relate to, then the MOD is exactly the shock you are looking for.

Technologies of the Formula MOD shock absorber


Large Volume Bladder (LV)

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 Formula to minimize friction and inertia in the system and achieve an excellent sensitivity to small bumps.

High Flow

The MOD was designed with the concept of High Flow in mind. The 30 mm 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.

CTS (Compression Tuning System)

The Mod is Formula's first shock with CTS (Compression Tuning System) technology. Formula wanted to have the trademark of their forks on on their first MTB shock, too. Thanks to CTS technology, anyone will be able to tune the rear suspension quickly and easily. CTS means fine-tuning within everyone's reach.
