The 2021 Union Union STR binding delivers high-level performance at a fraction of the price. Featuring tech found on high-end bindings, stripped and refined to shave cost, the STR is a durable, comfortable, and performance-focused all-mountain binding that leaves you plenty in the bank to bring the rest of your setup up to its level.
This Union binding comes with a Universal Disk, compatible with 2x4, 4x4, and channel binding mounting systems.
Stage 5 Duraflex Baseplate
Designed as an all-mountain and freeride base, the ST Stage 5 is lightweight, canted for comfort and power, and offers bomb-proof durability for long lasting performance.
The STR2 highback borrows the design from the previous Travis Rice pro model, featuring a dual-material construction that alters the flex through select areas of the highback to offer more support and response where you need it most.
A smooth and fast mechanism combined with Union aluminium creates a light and durable ratchet that feels good, looks good, and works even better.
Exoframe Ankle Strap + TS-1.0 Hexgrip Toe Strap
The ExoFrame ankle strap functions as a suspension system for your feet, boasting improved comfort and greatly reduced weight compared to previous models. The Ultragrip toe strap can be worn as a toe strap or cap strap and is made of a highly durable, super grippy thermoplastic material, keeping you securely locked in at all times.
EXT Thermoformed EVA
EXT Thermoformed EVA bushings offer multiple season durability along with a smoother ride, enhanced comfort, and extra impact and vibration absorption when you need it most.
Extruded 3D Aluminium Heelcups:
This heelcup increased the stiffness of the binding, increases response, and is adjustable to help you dial in the perfect fit.
Mini Forward Lean Adjuster:
No tools needed for this one, just flick the tab down and slide the panel for more response or a looser feeling ride on the fly.
Grade 8.8 Hardware:
Union ensure their hardware is reliable by using the strongest steel available on the market.
The footbed of this binding is angled to better align your joints and provide a more natural feeling, less fatiguing ride.
