A cutout baseplate and medium-flex Asym Rip 'N' Flip highbacks put it at 628 g per binding in a Medium, and the flatter upper highback section leaves superior lateral mobility for a surfy ride down.

Weight is quoted at the Medium, and the other sizes differ. The board side of the setup is the part to plan: the Arc ST needs a set of Spark Flat Pucks or Spark Canted Pucks, sold separately, and the binding then works with any puck-compatible splitboard. Canted pucks add a few degrees of inward tilt at the feet, which some riders find easier on the knees over a long tour.\u003c\/p\u003e\n\u003cp\u003eTwo compatibility details matter if you are mixing generations of hardware. ST bindings work only with ST Whammy Bars, and 2021\/22 or older T1 bindings need the standard Whammy Bar instead. Going the other way is fine: ST bindings run on older Tesla brackets with brass bushings, and older T1 bindings run on ST brackets. Check which generation your existing parts are before ordering spares, because the whammy bar is the one part that does not cross over.\u003c\/p\u003e\n\u003cp class=\"ccbb-rating-key\"\u003eMounting and setup guidance reviewed by CCBB splitboard staff.
