Dynafit Blacklight Long Travel — Review

Overview

The Dynafit Blacklight Long Travel is a lightweight tech/pin touring binding in Dynafit’s “Speed” line. It pairs an adjustable lateral release (DIN 5–12) with a fixed vertical release, a generous 50 mm heel adjustment range, and meaningful heel elastic travel. At about 420 g per binding and brakes in 75/90/105 mm, it targets long days in the mountains without giving up too much downhill confidence.

Who is it for?

Ski tourers who value uphill efficiency but want more downhill composure than race-derived minimalism.
Ski mountaineers needing long heel adjustment to accommodate multiple boots or sole wear.
Less ideal for aggressive freeriders who require fully adjustable vertical release or a freeride spacer, or for very wide skis (>105 mm brake options).

Specs explained

Type: Tech/pin Touring — frameless pin binding optimized for efficient ascents and reliable descents.
DIN / release: 5–12 (lateral, adjustable); vertical fixed — you can fine-tune lateral release; vertical is set by the U-spring.
Elastic heel travel: ≈12–13 mm (reported) — improves retention over ski flex and rough snow, reducing pre-release.
Brake widths: 75 / 90 / 105 mm — select a brake ~5–10 mm wider than ski waist.
Weight: 420 g per binding — light enough for big vert without feeling flimsy.
Compatibility: Tech/Low‑Tech inserts (pin‑tech boots); crampon‑ready — not for alpine soles without tech inserts.
Materials: Forged aluminum, stainless steel, high‑tech composites — a durable, stiff, low‑weight build.

On the skin track & the descent

Uphill: Step‑In Side Towers and Ice Breaker pins speed up entry and clear ice. Speed Step risers (two positions + flat) are easy to flip with a pole.
Downhill: The bayonet heel lock and elastic travel deliver a more planted, predictable ride than many ultra‑light options. The caveat is the fixed vertical release—fine for many tourers, limiting for those who prefer dialing both axes.

Features that stand out

Bayonet heel lock: enhances power transfer and edge hold.
Ice Breaker pins: help keep inserts clear for reliable step‑in.
Step‑In Side Towers: faster, more guided toe entry.
50 mm Long Travel: ample BSL adjustment for different boots/sole wear.
Crampon slot and brake options: versatile across conditions.
Dynafit Lifetime Guarantee (with registration): confidence in durability.

Comparisons

Marker Alpinist 12: lighter on paper, but with less heel elasticity and a slightly harsher downhill feel. Blacklight LT feels calmer on hard snow; Alpinist wins on grams.
ATK Raider 12: similar class but with adjustable vertical release and optional freeride spacer, making it better for aggressive descents. Raider is more tunable; Blacklight LT is simpler and tour‑focused.
Dynafit Speed Radical: a touch lighter and cheaper, but with shorter length compensation and a less “locked‑in” heel feel. Blacklight LT is stronger on the way down.

Drawbacks

Fixed vertical (forward) release; no adjustment for skiers who want to tune both axes.
No freeride spacer; brake sizes top out at 105 mm.
Not the absolute lightest for pure speed‑touring missions.

Setup & use

Have a pro mount the bindings. Set heel gap with the supplied gauge, verify length compensation, adjust lateral DIN, and choose the right brake width. Test step‑in and riser transitions. Use brakes or a leash per local rules.

Frequently asked questions

Q: Will my boots work with the Blacklight Long Travel?
A: You need boots with tech/Low‑Tech inserts. Alpine soles without inserts are not compatible.

Q: How much elastic heel travel does it have?
A: Dynafit lists elastic heel travel but no official number; trusted buyer guides report roughly 12–13 mm, which helps retention as the ski flexes.

Q: What brake width should I choose?
A: Typically 5–10 mm wider than your ski waist. For a 96 mm ski, choose the 105 mm brake.

Q: Can I run it brakeless?
A: Yes, with a leash where permitted. Some resorts/regions require brakes—follow local regulations.

Key takeaways

Light and efficient: excels on long climbs and traverses.
Composed downhill: bayonet heel and elastic travel boost confidence.
Simple and durable: quality materials with a lifetime guarantee.
Trade‑offs: fixed vertical release and brakes only up to 105 mm.
