S11 Duraflex ST Baseplate
By removing excess material in the toe and heel of the baseplate, and utilizing an asymmetrical baseplate shape, we've been able to drastically increase the torsional flex of the binding. The Ultra's S11 Duraflex ST baseplate allows for 360 degree board flex and feel.
Molecular Bushing
Union's Molecular bushing provides spring-loaded take offs and perfectly cushioned landings. 15% lighter than Union Fused Vaporite and guaranteed to minimize foot, ankle and knee fatigue. This is the future of freestyle binding design.
TPE Outsole
Exclusive to Union, this 100% new binding manufacturing process requires zero bushing gluing and adds another layer of dampening and vibration canceling material to the all-new Ultra.
TS 5.0 UltraGrip Toe Strap
Multi-Positional options and thermoplastic anti-slip material keep you locked in and on point. The TS 5.0 UltraGrip toe strap is compatible with all boot brands and models.
Hybrid 1.0 Ankle Strap
Instant response meets all day long foot comfort. The Hybrid 1.0 ankle strap's construction combines our responsive Exoframe exterior with the padded comfort and flexibility of the Forma interior. Form fits perfectly to any boot on the market today.
Magnesium S1 Ratchets
Magnesium S1 ratchets are Union’s answer to the elements. A fully integrated spring protected from the harsh outside provides you with Union’s best ratchet to date. Longer life span and better spring return guaranteed.
Integrated 2-Stage Forward lean Adjuster
Fine-tune your forward lean angle with a #3 screwdriver to match changing terrain and riding styles.
S25 Ultra Duraflex ST Highback
6 degrees of preloaded forward lean hugs your boot and allows for quick edge to edge response. While a molecular highback bushing provides increased freestyle flex and rebound while riding. This unique highback construction is exclusive to Union Binding Company.
