Stage 11 ASYM Duraflex ST Baseplate
By removing excess material in the toe and heel of the baseplate, and utilizing a brand new asymmetrical shape, we've been able to drastically increase the torsional flex of the binding. The Ultra's Stage 11 ASYM baseplate allows for 360 degree board flex and feel.
