O’Brien Jr Siege Slalom Ski Z9 Binding Toe Plate

Description

Junior skiers need a slalom platform that responds quickly without overwhelming their size, and the O’Brien Jr Siege Slalom Ski Z9 Binding Toe Plate provides that direction in a 59-inch package. The ski includes a Z9 Junior front boot, rear toe plate, A.R.C. adjustable aluminum fin, lightweight closed-cell polyurethane foam core, fiberglass layup, tunnel concave, smaller defined bevels, and youth-tuned continuous rocker. The package suits intermediate to advanced junior skiers up to 120 lbs. ([obrien.com](https://www.obrien.com/collections/2026?utm_source=openai))

Suggested boat speed ranges from 20 to 32 MPH or 32 to 51 km/h. The 59-inch or 150 cm length gives younger riders a compact platform for fast edge-to-edge movement. Smaller bevels support turning response, while the tunnel contour provides water displacement and tracking stability. The A.R.C. fin block allows fore and aft position tuning, giving the skier a specific adjustment point beneath the ski. The Z9 Junior boot uses a lightweight chassis, front single-lace system, low flexible cuff, Lycra-lined liner, and EVA footbed. The rear toe plate includes a contoured rubber footbed pad.

Junior Course Progression and Tight Carves

This package suits junior skiers who already understand basic water-ski balance and want to develop sharper turns, edge changes, and course movement. The 59-inch length keeps the ski manageable, while the smaller bevels and continuous rocker provide a more responsive feel than a basic combo ski. Use the 20 to 32 MPH range as a guide and match speed to rider skill, weight, rope length, and boat setup. Select the Z9 Junior fit carefully before ordering. This package is aimed at progression, not first-time trainer use.
