100% pneumatic damping

Lightest system in the market

Medium weight reduction of 200gr.

increase in usable travel by 15/20%

Eliminates the fork’s pedaling induced oscillations

OVR is a system that applies resistance to low speed compression movement.

The OVR does not fully locks the fork, only parcial.
The OVR first objective is to find a good compromise between fork comfort and anti-oscillation / pedaling efficiency, without changing its tuning.
OVR anti-oscillation / pedaling efficiency improves when the user makes less projection of his weight over the front wheel.
With the application of OVR, the factory parameters are subject to the following changes:
  • – SAG changes approximately to 10%;
  • – Pneumatic spring pressure decreases by 30%, compared with pressures recommended by the manufacturer.
Unchanged factory parameters are:
  • – Maintenance interval;
  • – Chassis integrity;
  • – Chassis durability.

Indicative figures only, air pressure spring must be adjusted according to user requirements.

ROCK SHOX MODELS

Solo Air

Air pressure equal to user weight
e.g., 70 kg = 70 psi


Dual Air

Positive air chamber: Air pressure equal to user weight
e.g., 70 kg = 70 psi

Negative air chamber: Air pressure equal to user weight plus 35 psi
e.g., 70 kg = 70 psi + 35 psi = 105 psi


FOX MODELS

< 2016 Models

Air pressure must be 30% lower than user weight
e.g., 70 kg = 49 psi


≥ 2016 Models

Air pressure equal to user weight
e.g., 70 kg = 70 psi


OVR BUTTON ADJUSTER

Turn right for more OVR resistance
Turn left for less OVR resistance

SETTINGS

Adjust OVR while riding uphill in a standing position.

Adjust the OVR control knob until the desired locking resistance is achieved.

Make the OVR resistance adjustment to user minimum needs, since only 5% to 10% of all the track will be ridden in this position.

If the resistance adjustment is too high, it can reduce some comfort in all the other types of ride and style.


REBOUND BUTTON ADJUSTER

Red color
Turn right for more rebound
Turn left for less rebound

MAINTENANCE INTERVAL

The maintenance interval is the same as the fork manufacturer recommendations.

ATTENTION!

The OVR system works under very high pressure. Service must be performed by an authorized technical center. Once the OVR system is assembled, do not open it.
