ON3P Oski 102 Review

The ON3P Oski 102 is a park‑driven, all‑mountain‑capable freestyle ski built around ON3P’s RIPPER ROCKER. It pairs a longer contact length and higher camber for edge grip and pop with a durable, bamboo‑based construction that shrugs off park abuse. Think stout‑yet‑playful: supportive on landings and locked on rails, but still lively enough to butter and pivot when you bring an active stance.

Key takeaways

Edge grip + pop: RIPPER ROCKER and higher camber boost bite and rebound compared with many 100–105 mm twins.
Built to last: 2.5×2.5 mm edges, thick 1.8 mm base, UHMW sidewalls, and VDS damping are standout durability features.
Versatile width: 102 mm underfoot balances park stability with everyday all‑mountain use.
Stout flex, controlled feel: confident at speed and on big features; rewards good technique more than ultra‑soft jib skis.
Medium‑long turns: ~20 m sidecut favors calm, predictable arcs over twitchy short‑turns.

On‑snow performance

Groomers & hardpack: The longer effective edge and camber deliver above‑average grip for a twin at this width. The Oski feels composed in medium‑to‑long carves (forward and switch) with steady pressure build and dependable edge hold.
Park & switch: Excellent on rails with a firm underfoot platform and torsional backbone. The ski feels balanced in the air with supportive tails for bigger landings. Compared to ultra‑loose jib sticks, it asks for a bit more input to press and butter slowly, but pays you back with stability.
Mixed snow & soft snow: At 102 mm with generous tip/tail rocker, it planes well in resort pow and remains manageable in chop. Bamboo’s natural damping keeps things quieter than many lighter park skis. In true deep days, a wider twin will float more, but the Oski holds its own.

Build, materials & durability

100% vertically laminated bamboo core: lively rebound with natural damping and a solid snow feel.
2800 hybrid fiberglass + carbon: proprietary triax weave adds torsional strength and responsiveness without metal.
Full UHMW sidewalls + triple VDS rubber: strong bonding, impact resistance, and vibration damping.
Durasurf 4001 base (approx. 1.8 mm): thick, fast, and durable; easier to repair than many thinner park bases.
2.5×2.5 mm Rockwell 48 edges: among the thickest; park‑proof and long‑lasting.
Wide binding mat: improved screw retention and underfoot stiffness for rails and big landings.

Specs explained

Rocker profile (RIPPER ROCKER): longer contact length and higher camber for grip/pop; tip/tail rocker for pivot, pressability, and maneuverability.
Dimensions: tips/tails in the high‑120s with a 102 mm waist create stability on landings and helpful float; moderate taper keeps it predictable.
Turn radius (~18.9–20.8 m): favors smooth, medium‑long arcs and stability, especially at speed.
Weight (about 1.77–2.02 kg per ski by length): adds damping and confidence on landings; a touch heavier than ultralight park sticks.
Lengths (171/176/181/186) & mount (‑2 cm): ‑2 cm is a smart all‑round line; moving to center increases play at the cost of some grip/support.

Sizing & mounting

Sizing: Park‑forward skiers can go true‑to‑size; size up for more stability and all‑mountain speed. Many average‑build riders land on the 181 cm.
Mounting: Start at the recommended ‑2 cm. Go closer to center if rails/switch are your priority; stay near ‑2 cm for stronger carving and directional support.

Comparisons

Line Chronic 101: lighter and looser at slow speeds; Oski 102 has more bite, damping, and durability.
Armada ARV 100/106: ARV 100 is more jib‑friendly; ARV 106 floats more. Oski provides stronger edge hold and a stouter platform.
K2 Poacher (96): quicker edge‑to‑edge for comp‑style parks; Oski is more stable in chop and more versatile off‑piste.
Faction Prodigy 2: easier flex and lighter feel; Oski wins on durability and hard‑snow grip.
ON3P Jeffrey 102: Jeffrey leans all‑mountain playful; Oski’s longer contact length and camber put a sharper focus on park performance and grip.

Frequently asked questions

Q: Who is the ON3P Oski 102 for?
A: Riders who prioritize park but want a legitimate all‑mountain twin. If you value edge grip, pop, and durability in a freestyle package, the ON3P Oski 102 fits the bill.

Q: How does RIPPER ROCKER feel on hard snow?
A: The longer contact length and higher camber provide uncommon bite for a 102 mm twin. The ON3P Oski 102 feels planted in medium‑to‑long carves.

Q: Is it too heavy for park?
A: It’s on the solid side, which translates to stability, damping, and lifespan. Street‑jib purists may prefer lighter; for resort park, the extra composure is an asset.

Q: How does the ‑2 cm mount compare to center?
A: ‑2 cm balances carving support with switch performance. Center moves the balance toward rails and butters but costs some grip and directional support.

Bottom line

The ON3P Oski 102 combines real park chops with hard‑snow grip and standout durability. If you want one freestyle ski that carves as confidently as it lands and slides, this should be on your shortlist.
