ATK Trofeo Plus — Expert Review
Overview
The ATK Trofeo Plus is an ultralight race/speed-touring tech binding built for maximum efficiency. At a claimed 170 g per binding, with fixed vertical and lateral release (4/6/8/10) and a minimalist 7075 aluminum/titanium build, it targets skimo racers and uphill-focused tourers who value fast ascents and precise, controlled descents. The PLUS spec adds three climbing positions, an R01 adjustment plate (~30 mm), and a speed kit (Kevlar leash, removable crampon receptor).
Who is it for?
- Skimo racers and speed-tourers seeking minimal weight and direct power transfer.
- Skiers on narrow-to-mid touring skis (~60–95 mm) who prioritize efficiency over features.
- Not ideal for wide/heavy setups, aggressive resort laps, or those wanting adjustable release and brakes.
Highlights and technologies
- Easy Entry System: Smoother step-in, even with worn tech inserts or cold, sticky snow.
- Monolink 1.0: One fixed toe arm for added stiffness and weight savings.
- Fixed release options: 4/6/8/10 (vertical/lateral) chosen at purchase.
- Three climbing modes: Flat, +43 mm, +49 mm (PLUS) for efficient uphill cadence.
- R01 adjustment plate: About 30 mm of BSL range for flexibility across boots or resale.
- Optional brake (R15): Binding ships brakeless; speed kit includes Kevlar leashes.
On-snow performance
- Uphill: Minimal mass and useful risers make long climbs feel easier. The removable crampon receptor accepts ATK/compatible crampons for icy traverses.
- Transitions: Quick and intuitive. Few moving parts mean fewer fiddly steps; lifters flip cleanly with a pole.
- Downhill: Delivers a precise, connected feel—excellent on light, narrow skis and race-style lines. The trade-off: no elastic travel and no release adjustability, so margin for error is lower in rough snow. Choose your release value wisely and stay within the intended use.
Specs explained
- Type of binding (Tech/race): Pin toe and heel for minimal weight and efficient power transfer; requires tech-compatible boots.
- DIN / release value (4/6/8/10 fixed): Determines when the binding releases; fixed spec gives consistent behavior but no fine-tuning.
- Elastic travel (0 mm): No heel elasticity; lighter and more direct, but less forgiveness under high impacts.
- Brake width (no brake): Lowest weight and simplicity; leashes included. Optional R15 brake adds safety at a weight penalty.
- Weight (170 g per binding): Major benefit for climbing efficiency and reduced fatigue.
- Compatibility (tech soles; skis ~60–95 mm): Works with pin-insert boots; pairs best with light, narrow-to-mid touring skis.
- Materials (7075 aluminum, titanium U-spring, stainless steel, POM): High stiffness/durability at very low mass.
Comparisons
- Dynafit Low Tech Race 105: Lighter (~105 g) but more Spartan (fewer risers/features). Trofeo Plus wins on day-to-day usability and adjustability (R01 plate) at a small weight cost.
- ATK Trofeo (non-Plus): Slightly lighter (~145 g) but lacks the extra riser and adjustment. The Plus is more versatile for everyday speed touring.
- Plum Race 150: Similar weight and race focus; ATK’s EES and Monolink deliver smooth step-in and stiffness. Both have fixed release values.
- Marker Alpinist 8/10: Heavier (~245 g) but with DIN adjustability and brakes—better for general touring than pure racing.
Key takeaways
- Ultralight race DNA: Maximizes uphill efficiency and delivers a sharp, precise feel.
- Fixed release: Pick 4/6/8/10 carefully; there’s no fine adjustment or elastic heel travel.
- PLUS advantages: Three risers, R01 plate, and speed kit improve everyday usability.
Frequently asked questions
Q: Which release value should I pick (4/6/8/10)?
A: As a rule of thumb: 4 for very light/technical racers, 6 for most light/medium skiers, 8 for stronger or heavier setups, 10 for heavy/very aggressive skiers. Consult a shop based on your weight, style, and ski length.
Q: Can I add brakes?
A: Yes—the optional ATK R15 brake fits, adding weight and complexity. The speed kit includes Kevlar leashes for brakeless setups.
Q: Will it adjust to different boots?
A: Without the plate there’s essentially no adjustment; with the R01 plate you get about 30 mm of BSL range. Ideally mount to your primary boot.
Q: Is it safe for resort use?
A: It’s designed for backcountry race/speed touring. Fixed release and no elastic travel limit versatility on-piste; consider an adjustable, brake-equipped binding for resort laps.
Verdict
For dedicated weight savers and skimo athletes, the ATK Trofeo Plus delivers elite climbing efficiency and precise downhill control in a featherweight package. Select the right release spec and pair it with appropriately light skis to get the most from this binding. If you want brakes, adjustable release, and more forgiveness, look to all-round tech bindings instead.
