The All-New Union STR is the binding for stepping up to larger drops and more technical lines. For riders looking for the performance of the Atlas at a price that’s nice, the STR maintains everything you would expect from our high end. Canted Stage 5 Base, TR16 Highbacks and Classic+ straps make choosing the STR a no-brainer.
Unprecedented performance for the price, the STR represents our philosophy that there is no such thing as “entry level” in our family of bindings. Constantly investing and reinvesting into product is what sets Union apart from the competition.
Ideal for riders using a wide stance, Canted Gas Pedals on the STR supply extra leverage and ollie power. Canting also allows the ankle and knee joints to be aligned, alleviating pain.
STAGE 5 DURAFLEX BASE
The Stage 5 Base is perfect for All Mountain / Freeride based riders looking for serious bang for the buck. Canted and bombproof, this binding blows away everything in its class.
CANTED THERMOFORMED EVA BUSHINGS
Canted Gas Pedals supply extra leverage and ollie power. Canting also allows the ankle and knee joints to be aligned, alleviating pain.
EXTRUDED 3D ALUMINUM HEELCUPS
The rigidity and strength of Extruded Aluminum acts like a roll cage on a race car - stiffening the entire chassis. The male/female connection with the base provides seamless response.
Developed with the same mentality as the Falcor Highback, the TR16 features a dual material combo, which progressively increases heelside control while allowing lateral comfort.
CLASSIC+ ANKLE STRAPS
Three dimensional Direct-Connect core evenly distributes strap pressure and allows lateral freedom. Minimized Stitching provides exceptional durability.
ULTRAGRIP TOE STRAPS
Multi-Positional options and thermoplastic anti-slip material keeps you locked in and on point. Each version has differing amounts of material based on weight.
