Dynafit Low Tech Race 115 Auto Lock

Overview

The Dynafit Low Tech Race 115 Auto Lock is a purpose‑built skimo race binding that chases grams without sacrificing essential reliability. At 115 g per binding, with an Auto‑Lock toe and Ice Breaker pins, it’s engineered for fast ascents and clean transitions. Release values are factory‑fixed (no user‑adjustable DIN). A 68 mm race brake and a ~20 mm heel adjustment plate are available as options. The ultra‑low stand height sharpens snow feel and power transfer.

Who is it for?

Ski‑mountaineering racers and weight‑conscious tourers who want the lightest, simplest tech setup that still releases consistently.
Minimalists who prioritize uphill speed and efficient transitions over maximum downhill comfort and elasticity.
Not ideal for wide skis, aggressive resort laps, or riders who need adjustable DIN and long elastic travel.

Uphill and transitions

The Auto‑Lock toe speeds up transitions and resists unintended opening on steep skin tracks. Ice Breaker pins help clear frozen inserts, reducing fumble time in cold, icy conditions. Paired with the low stand height, the stride feels efficient and direct. Adding the optional brake boosts safety and race compliance but increases weight.

Downhill performance

For a 115 g binding, downhill control is impressive on narrow, lightweight race skis. Release is predictable but non‑adjustable. Elastic travel is not published—and, as with most race tech heels, is limited—so there’s less margin on choppy snow than with heavier touring bindings. If you want more damping and elasticity, consider a burlier tech model.

Specs explained

Type of binding: Tech (race touring) — Pin toes with a lightweight heel; maximizes uphill efficiency with a minimalist downhill feel.
DIN/release value: Fixed (non‑adjustable) — Consistent race‑style release; cannot be tuned to rider weight/style.
Elastic travel: Not specified — Typical race tech heels have minimal vertical movement; less buffer on hard impacts.
Brake width: 68 mm (optional) — Narrow race brake, sold separately; adds safety but costs grams.
Weight: 115 g per binding — Extremely light; reduces fatigue and speeds vertical gains.
Compatibility: Boots with tech inserts; optional ~20 mm heel adjustment; crampon slot — Versatile within race/light touring.
Materials: Forged aluminum, stainless steel, high‑tech polymer — High stiffness‑to‑weight with corrosion resistance.

Comparisons

ATK Trofeo: Slightly heavier, often offers multiple U‑spring options (different release levels). The Dynafit is lighter and more “set‑and‑forget,” but less tunable.
Ski Trab Gara Titan: Similar weight and race focus; the Trab offers a different operational feel. Dynafit’s Auto‑Lock and low stand height are strong advantages.
Plum R170: Heavier and more robust; can feel calmer on the way down. The Dynafit wins on pure climbing efficiency.

Mounting and setup

Precision mounting is critical—have a race‑savvy shop do it. The optional adjustment plate provides roughly 20 mm of heel travel to accommodate different BSLs or multiple boots. Periodically check screw torque and toe insert wear, especially with race boots.

Durability

With forged aluminum, stainless steel hardware, and high‑tech polymers—plus German manufacturing and the Dynafit Lifetime Guarantee—the build inspires confidence. Used within its design scope (racing/light touring), longevity is excellent; avoid oversized skis and abusive terrain.

Potential drawbacks

Non‑adjustable release and limited elasticity.
Brake is optional and adds weight/complexity.
Few comfort features compared to tour/race hybrids.

Key takeaways

Pure race focus: 115 g and Auto‑Lock make transitions fast and reliable.
Fixed release: predictable but not tunable to rider or conditions.
Best on narrow, light skis: heavier tech bindings suit hard charging better.

Frequently asked questions

Q: Will it work with my boots?
A: Yes, if your boots have tech (pin) inserts. Inspect inserts for wear; tight tolerances matter for the Low Tech Race 115 Auto Lock’s clamping and release consistency.

Q: Can I adjust the release (DIN)?
A: No. Lateral and vertical release values are factory‑fixed. If you want options, consider systems with multiple U‑spring choices or adjustable touring tech bindings.

Q: What brake width should I choose?
A: The common race brake for this model is 68 mm. Choose a brake just wider than your ski’s waist without excessive overhang.

Q: Is it suitable for resort skiing?
A: It’s designed for skimo racing and light touring. For daily resort use and higher‑impact descents, a heavier, DIN‑adjustable binding is recommended.
