Fischer RC4 STI – Review & Test

Overview

The Fischer RC4 STI is a sporty, on‑piste carver built for short to medium turns. With a 68 mm waist, On‑Piste Rocker, and a Power Ti layup, it blends tenacious edge grip with reassuring stability. It’s not a FIS SL weapon; rather, it’s an energy‑saving, lively piste tool that helps you carve cleaner arcs for longer with less effort.

On‑snow performance

Edge hold and precision: The 3°/1° factory tune and Race Sidewall deliver quick, authoritative bite on hard or icy mornings. Edge‑to‑edge is fast and predictable.
Turn shape: Feels naturally short‑to‑medium. The ski pulls you into the turn and releases with a tidy rebound—lively but not punishing.
Stability and damping: Power Ti keeps the tip composed in ruts and at pace. There’s enough damping to feel calm without muting the ski’s energy.
Forgiveness: Strong intermediates and advanced skiers will click with it immediately; it rewards good fundamentals without demanding racer aggression.
Limits: In cut‑up or slushy bumps the 68 mm waist is less forgiving. For very high speed and long GS arcs, you’ll find a sensible ceiling—consider a longer length or a more GS‑leaning model.

Construction and tech

Beech‑poplar wood core + Power Ti: direct power transfer, torsional stiffness, and edge grip.
Sandwich/Race Sidewall: precise edge pressure and durability.
Sintered base: good glide and wax retention.
RS10 GW Powerrail set: easy adjustability; powerful/heavier skiers may prefer a higher‑DIN binding for headroom.

Ideal buyer (and who should pass)

Best for: advanced to expert piste skiers who love rhythmic short‑to‑medium carves and dependable hard‑snow grip.
Not ideal for: powder, heavy bumps, or those who only want fast, long GS turns. Dedicated racers may want a stiffer, race‑room option.

Comparisons

Atomic Redster S9 Revo: more serious and stiffer with laser precision; the RC4 STI is more forgiving and less fatiguing.
Rossignol Hero Elite ST TI: similar radius; Rossi is a touch looser in the tip, Fischer feels calmer and more planted on boilerplate.
Head Supershape e‑Original/e‑Magnum: Heads are ultra‑accessible and energetic; Fischer brings a slightly more “racey” edge feel and composed damping.

Length and setup advice

Length guide: body height minus 10–15 cm for a short‑turn focus; if you’re heavier, aggressive, or prefer more medium turns, choose closer to minus 5–10 cm or size up one step.
Mount/stance: neutral works best; a slight forward stance can quicken engagement—keep balance centered.
Binding: RS10 GW is fine for most; powerful skiers might look for a DIN 12–14 option.

Specs (and what they mean)

Rocker profile – On‑Piste Rocker/camber: light tip rocker for easy turn initiation; camber underfoot for grip and rebound.
Sidecut 117‑68‑105 mm: a narrow 68 mm waist speeds edge‑to‑edge; the slimmer tail cleans up the exit reliably.
Radius (14.5 m at 163 cm; per length 13.0–15.5 m): delivers short‑to‑medium arcs with lively rhythm.
Weight (1880 g per ski): enough mass for composure without feeling sluggish.
Edge tune (3°/1°): assertive factory angles for strong bite—keep sharp for best performance.
Lengths: 149/156/163/170/177 cm.

Key takeaways

Hard‑snow specialist for short‑to‑medium carves with high grip.
Lively yet composed; rewarding without being exhausting.
Less happy in slush and moguls; consider longer or different model for GS speeds.
