The Union Source FC represents a revolutionary leap in snowboard binding design, delivering unprecedented lightweight performance through forged carbon construction and innovative mounting technology. At just 540 grams per pair, this binding weighs as much as a single traditional binding, yet delivers maximum response and durability for riders seeking the ultimate connection to their board.
Union's Lab project, developed over the past decade, has finally reached production with the Source FC. This binding eliminates traditional design constraints by removing the disc entirely, using a two-screw mounting system that brings riders closer to their snowboard than ever before. The forged carbon components, manufactured in Italy, create a binding that feels almost weightless while maintaining the bombproof durability Union is known for.
Revolutionary Two-Screw Mounting System
The Source FC completely reimagines how bindings connect to snowboards. Instead of the traditional four-hole disc pattern, this binding uses just two screws: one rear mounting point and one front pivot point that adjusts your stance angle. This design eliminates the dead zone created by large insert packs and discs, allowing for more natural board flex and foot steering.
The mounting system offers a range from +21 to -3 degrees, accommodating most riders' stance preferences. While some riders prefer more extreme angles, this range covers the vast majority of applications from freestyle to freeride. The two-screw design reduces weight significantly while maintaining the same level of security and connection as traditional four-hole patterns.
The Source FC's two-screw mounting system eliminates the dead zone underfoot, creating a more direct connection to the snowboard that enhances board feel and allows for natural flex patterns that traditional bindings restrict.
Years of research and development, including extensive testing with professional riders, have proven this mounting system's durability and performance. The forces and stress that elite riders put on their gear have validated the Source FC's ability to handle everything from park laps to big mountain lines.
Halo Technology and Forged Carbon Baseplate
The Source FC features Union's proprietary Halo technology, which creates a donut-shaped baseplate that sits directly on the snowboard. The forged carbon piece sits inside this baseplate, creating a unique combination of toe-to-heel response and lateral movement. This design promotes natural board flex while delivering immediate energy transfer.
The baseplate itself is shaved down to mere millimeters in thickness, bringing riders as close to the snowboard as physically possible. This ultra-low profile creates a lower center of gravity that dramatically improves balance and riding efficiency. The feeling is almost indescribable. Riders report feeling like they're standing directly on the board with no binding between their feet and the snow.
This reduction in material between rider and board creates more immediate reactions to input. Every movement translates directly to the snowboard without the delay that thicker baseplates introduce. For riders who prioritize board feel and responsiveness, this design represents the pinnacle of binding technology.
Forged Carbon Components
Every forged carbon component in the Source FC is manufactured in Italy by specialists who have perfected the process. The forged carbon highback delivers maximum response with minimal weight, while the forged carbon heel cup provides exceptional strength at just 45% of the weight of traditional aluminum heel cups.
The forged carbon ankle strap is unique to the Source FC, shaved down to eliminate every unnecessary gram while maintaining the security and adjustability riders need. This strap design represents Union's commitment to weight reduction without compromising performance or durability.
The binding also features two toe ratchets, a design choice that eliminates weight while providing the same level of adjustability and security as traditional single-ratchet systems. This attention to detail throughout the binding demonstrates Union's obsession with creating the lightest possible binding without sacrificing any performance characteristics.

Ultra-Lightweight Performance
At 540 grams per pair, the Source FC weighs less than most single bindings from other brands. Even when compared to Union's already lightweight lineup, this binding represents a significant reduction in weight. The regular Source model, which uses more traditional materials, still weighs just 640-680 grams per pair, making even the "heavy" version incredibly light.
This weight reduction translates directly to riding performance. Lighter bindings reduce fatigue throughout the day, making every chairlift ride, traverse, and hike more efficient. The cumulative effect of carrying less weight becomes noticeable after just a few runs, and by the end of the day, riders feel fresher and more capable of pushing their limits.
The Source FC's 540-gram weight feels almost unreal when you first pick it up, but the true magic happens on snow where the reduced weight combines with the ultra-low profile to create a riding experience that feels like floating above the board.
The weight savings don't come at the expense of durability. Union has ensured that every component, from the Grade 8 hardware to the forged carbon pieces, meets the same durability standards as their heavier bindings. This binding is designed to last multiple seasons of hard riding without showing signs of wear or performance degradation.
Source vs Source FC
Union offers two versions of the Source binding: the Source and the Source FC. Both share the same revolutionary baseplate and two-screw mounting system, but differ in their component materials. The Source uses a Duraflex highback, extruded aluminum heel cup, and the same strap found on the Falcor binding, while the Source FC uses forged carbon for the highback, heel cup, and ankle strap.
The Source FC delivers slightly faster response due to the carbon components, which engage immediately without the slight delay that Duraflex materials can have. However, the carbon's stiffness requires riders to match that performance level. This binding is designed for riders who want maximum response and are capable of handling that level of precision.
The regular Source provides a more accessible entry point into this technology, offering the same low-profile baseplate and mounting system with slightly more forgiving materials. Both bindings deliver exceptional performance, with the choice between them coming down to rider preference and performance requirements.
Hardware and Accessories
Every Source FC comes with specialized hardware designed to shave off additional weight. The hardware isn't standard Grade 8. It's elevated beyond that specification to meet the binding's weight requirements while maintaining strength. Each box includes a special Torx wrench and Allen key to properly manage this hardware, as it requires specific tools rather than standard screwdrivers.
The binding includes all necessary mounting hardware, including inserts and screws. The forward lean adjustment uses a screw on the back of the highback, and every pair comes with three different forward lean settings. Riders can change these settings on the hill if needed, though most prefer to set it up in a warm cabin and leave it.
The packaging itself reflects the premium nature of this binding. Each box includes a card that makes buyers part of an exclusive club, recognizing that these high-end bindings won't be common on the mountain. The included accessory pack can double as a glasses case or storage for other small items, adding value beyond just the binding itself.
For riders building a complete setup, pairing the Source FC with a responsive board creates an incredibly light and efficient package. Explore our complete bindings collection to see how the Source FC compares to other high-performance options.
Riding Experience and Board Feel
The Source FC's true innovation becomes apparent the moment you step into them. The ultra-thin baseplate and low-profile design create a sensation that's difficult to describe. It feels like there's no binding between your feet and the board. This direct connection enhances every aspect of riding, from edge-to-edge transitions to ollies and landings.
The binding's ability to promote natural board flex means riders can feel the board working beneath them in ways that traditional bindings dampen. Foot steering becomes more intuitive, and the board responds immediately to subtle weight shifts. This level of board feel is typically only available to riders who have spent years developing sensitivity, but the Source FC makes it accessible to anyone.
When paired with a high-performance board like the Capita Mega Death, the Source FC creates a setup that feels almost unreal in its lightness. The combination of a lightweight board and these bindings results in a package that riders can't believe is real until they pick it up and ride it.
Durability and Longevity
Despite its lightweight construction, the Source FC maintains Union's reputation for bombproof durability. The forged carbon components are incredibly strong, and the simplified design eliminates many of the failure points found in traditional bindings. The binding's structure carries loads efficiently, ensuring that it will last for multiple seasons of hard riding.
The Grade 8 (and beyond) hardware ensures that mounting points remain secure even under extreme conditions. The binding's construction quality matches the level of refinement found in Union's prototypes, which have been tested and refined over several seasons before reaching production.
