The Plum Serak takes the DNA of the Oazo and makes it tougher and smarter for skiers who spend their time far from the trailhead. The heel now runs on a worm screw track instead of tension bolts, which means no more stripped heads or loose hardware mid-mission. That screw also unlocks 25 mm of fast, precise boot-length adjustment, ideal if you rotate through a few different boots. Plum also built in four millimeters of elastic heel travel. Paired with the standard 4 mm gap, you get 8 mm of total dynamic movement, enough to let your ski flex naturally, keep power transmission smooth, and cut down on those annoying pre-releases. The result is a binding that balances stripped-down weight with all the functional details you actually want when the days are long and the descents are real. 4 mm of elastic heel travel to absorb ski flex and resist pre-release. 25 mm of BSL adjustment keeps multiple boots in play. Worm screw system means no stripped bolts and no creeping heel pieces.
