PTO Verdict
“Slalom-tight turns and swallowtail play — a ski that demands the right terrain, not an expert driver.”
Best for: Skiers who turn constantly and want tight, high-energy carving plus butters, switch and sidehits on one groomer-centric ski — it comes especially naturally to freestyle backgrounds.
Not for: Powder days — at 87mm it will not carry you past roughly six inches of fresh, and the swallowtail does not change that. Hard chargers — point it through chop at speed and it gets knocked off line. Boilerplate ice — edge grip is OK, not great, despite the single titanal plate. And if one ski has to cover regular off-piste days, Black Crows' own line answers that with the Vena Cor or the Camox instead.

Description
The Black Crows Mirus Cor is a swallowtail carving-freestyle ski — 87mm waist, 13m radius at every length — designed to be skied short. Black Crows frames it as an alliance of two worlds, angular piste carving on one side and freestyle play on the other, and the geometry backs that up: every length from 160.1 to 184.2cm carries the same 13m radius, so turns come in quick and tight whatever the size, and the brand's own advice is to go shorter than usual and play with the piste. It carries into 26/27 as a straight carryover — same geometry, same construction, same size run.
Underneath sits a poplar/fiberglass core in a semi-cap construction with ABS sidewalls all the way around, plus a single titanal plate — a mid-weight resort build at 1,700–1,925g per ski, neither a lightweight nor a race layup. The tip and tail carry a long rocker, and the tail is cut into a swallowtail. Black Crows publishes no rocker measurements, flex number or swallowtail mechanism, so none are claimed here. What you feel, per PTO's own three seasons on this ski, is a ski that rolls into short, angular carves willingly and stays soft enough through the middle to press, butter and land switch.
It suits skiers who turn constantly — groomers first, bumps and trees close behind — and comes especially naturally to anyone with a freestyle background. It is not a powder ski: 87mm with a soft-ish middle won't carry you past about six inches of fresh. It also gets pushed around in chop at speed, and edge grip on boilerplate ice is OK, not great. If your season includes regular off-piste days, look at the wider Vena Cor or Camox in the same line.
Five lengths — 160.1, 168.3, 173.2, 178.0 and 184.2cm — at $999. The Mirus Cor is sold flat, without bindings; we mount them and help you settle both the binding choice and the length question in the shop, where shorter than your usual all-mountain size is the starting point.

Black Crows Mirus Cor
By PTO Team, Based on Black Crows' official 26/27 specs and one independent test · Spec analysis
The take
“Slalom-tight turns and swallowtail play — a ski that demands the right terrain, not an expert driver.”
The Mirus Cor is Black Crows' piste-side oddball: slalom-like in turn shape, freestyle in attitude. The construction story lives in the description above; this review is about evidence and boundaries. For 26/27 the ski is a carryover — same style number, same geometry, same per-size weights, and no update language in the official 26/27 materials — so 25/26 test evidence applies to this year's ski.
On snow the Mirus Cor does what the geometry promises: turns fall in on their own, and switch and butters come naturally off the forward mount — about -3.5cm from true center per the independent test's spec sheet, matching our own measurement of the ski in the shop. The short radius pays off in bumps and trees as much as on corduroy, and the independent test read the character the same way: a playful, quick, short-radius carver.
The limits are consistent across sources. Neither Black Crows' own materials nor the independent test treats it as a powder ski — at 87mm with a soft middle, the float ceiling sits around six inches of fresh, and the swallowtail does not change that. Pointed through chopped snow it gets deflected, and on boilerplate ice the edge grip is merely OK; the single titanal plate does not buy race-carver bite. Where sources genuinely split is how much that matters: the independent test frames it as a conditions-dependent quiver ski for advanced and expert skiers, while Black Crows itself describes the ski as accessible. Both agree on the weaknesses; the disagreement is about how big a slice of your skiing the strengths cover.
Within the line, the new-for-26/27 Vena Cor changes the conversation: a 100mm sibling that Black Crows itself pitches as 'a ski that does everything, but better' and an independent preview calls a riff on the Mirus Cor with a matching swallow tail — the pick if you want this DNA with real soft-snow range, at the same $999. Next to it, the Mirus Cor stays the sharper, quicker piste tool. The Octo (84mm, $949) — 'Mirus Cor's younger cousin' in Black Crows' own words — is the closest piste-play alternative in the line; the Serpo (93mm, $999) is the conventional, non-swallowtail piste-plus ski; the Camox (97mm, $849) is the all-terrain daily driver.
Sizing runs from 160.1 up to 184.2cm across five lengths, and Black Crows' official guidance is to ski it short — pick the shorter of the two lengths you sit between. MSRP is $999, and the ski is sold flat — the binding is a separate purchase, and we mount it and settle the length question at the shop.
Bindings we'd pair with it
Mount point: Flat ski — sold without bindings. The independent test's spec sheet puts the recommended mount at -3.5cm from true center, matching PTO's own measurement; Black Crows does not publish one. Our pick: Look Pivot 15 GW with the B95 brake.
- Look Pivot 15 GW B95Freestyle-leaning skiers
Our freestyle-leaning shop pick, taken with the B95 brake — we match brake width to the ski at mounting.
- Marker Griffon 13 IDAll-mountain everyday
Shop all-mountain option; our techs handle mounting and the brake-width match at fitting.
- Marker Squire 11Lighter skiers / value
A shop option for lighter or less aggressive skiers. The release setting is determined by a technician at fitting.
These are shop suggestions, not official pairings — Black Crows publishes no recommended binding for the Mirus Cor. Mounting, brake-width match and release settings are handled by a technician at fitting.
Common Questions
- What is the difference between the Black Crows Mirus Cor and the Vena Cor?
- The Vena Cor is a new-for-26/27, 100mm-wide sibling aimed at all-terrain and soft snow; one independent preview describes it as a Mirus Cor riff with a matching swallow tail, and Black Crows calls it 'a ski that does everything, but better'. The Mirus Cor is the narrower, quicker piste tool of the two. Both retail at $999.
- Is the Black Crows Mirus Cor good in powder?
- No — Black Crows' own materials and one independent test agree it is not a powder ski. At 87mm with a soft middle, the float ceiling sits at about six inches of fresh; the swallowtail does not change that. For soft-snow range in the same family, consider the 100mm Vena Cor.
- What length Black Crows Mirus Cor should I get?
- Shorter than your usual all-mountain length — Black Crows officially says this ski should be skied short. It comes in five lengths from 160.1 to 184.2cm, and the 13m radius is identical at every length, so sizing down keeps the turn shape. We help you settle the length at the shop.
- Did the Black Crows Mirus Cor change for 26/27?
- No — it is a carryover. The 26/27 ski keeps the same style number, size run, geometry, radius and per-size weights as the 25/26 version, and the official 26/27 materials contain no update language for it.
- Is the Black Crows Mirus Cor good for intermediate skiers?
- Yes, with the right terrain. The ski is forgiving and officially described as accessible, while one independent test skews advanced-expert. The real filter is terrain — groomers, bumps and trees, not powder or ice.
