GARMIN AND MAGENE ARMS MUST BE PURCHASED SEPARATELY!
(see compatible options)
NOTE: No mount arm is needed for GoPro, similarly attached devices, or the Garmin eRTL615, but a safety tether is recommended.
The Oca FX is our latest addition universal mount designed for saddles ranging from standard rail width to broad rail spreads (see details below). This mount has a fixed neck for added strength and able to accommodate any Varia model, Magene radar, or GoPro camera. It is purpose built to handle the weight of the Varia RCT715.
PLEASE NOTE: For GoPro or other camera setups, purchase the safety tether add-on separately. See details below.

Oca FX Key Features
![]() |
Based on community voting, the Oca uses locknuts to eliminate the need for threadlocker and ensure screws can't loosen. |

Anti-slip pads are integrated into the mount. They are tough while being carbon rail safe. The back of the clamp also includes a tab that keeps the body and clamp in alignment for improved grip. | ![]() |

The shape of the neck is designed to provide strength and clearance. We shaped the neck to accommodate the RCT715 and balance it for optimal performance which helps reduce jitter in the un-stabilized camera. This also adds greater stability for all other cameras as well as the other Varia radar models. |

The one piece body and neck are incredibly strong and able to support the weight of the RCT715 Varia radar and pretty much any other camera you can throw at it that fits. | ![]() |

Saddle Compatibility

The Oca clamps to the lower part of the rails that are parallel to the ground. The minimum width is 35 mm (1-3/8") on the inside and 70 mm on the outside. The rails can be round or oval, but must be between 6.5 and 10 mm thick (most are). You must have 30 mm (1-1/4") of clearance between the rail top and the bottom of the saddle. The back center top of the saddle must be open and clear of obstructions. |
---|
The Oca is designed to accommodate rails that tilt inward at the back (TT saddles) as well as those that spread out like a 'Y' (Brooks saddles). As long as the clamp fits within the rail space, it is fine to clamp it there. | ![]() |
