Blizzard has once again tweaked the Bonafide. The last time they did this, I argued that the update was a complete and total success, and I even went so far as to call the 15-16 / 16-17 Bonafide “perfect.”

(You can check out my review of the 15-16 / 16-17 Bonafide, as well as my Deep Dive article on Blizzard’s entire freeride lineup.)

But if you’ve achieved perfection, you can’t by definition, make improvements, right? You can, however, make things different.

Of course, perfection is in the eye of the beholder, so the most important questions here are:

  1. How similar or different is this new Bonafide from the previous one?
  2. Who will now prefer this new Bonafide to the previous Bonafide, and why?
  3. How does this new Bonafide stack up to the current crop of skis in this category?

Here’s what Blizzard has to say about the new Bonafide:

“Just when you thought your favorite ski couldn’t get any better, it did. The all-new Bonafide features new shapes that up this perennial favorite’s game, making it more versatile than ever.

New sidecuts and rocker profiles make it easier to ski, while the proven Carbon Flipcore™ with two sheets of metal makes it calm, confident and powerful.

Attack the mountain in powder, crud, groomers or rock hard snow and feel the precision and exhilaration that athletes and testers rave about.”

Ok, so the new sidecut and rocker profile are the noted differences here, and we have confirmed that the core construction has not changed in this new version of the Bonafide. So evidently, the name of the game here is that it is now “easier to ski” and “more versatile than ever.”

We never found the previous Bonafide to need a bump in versatility, but we’ll be weighing in soon on that “easier to ski” part. Now, let’s say more about that new sidecut…

Dimensions / Sidecut Radius

As you can see in our measured specs above, the 17/18 Bonafide is a touch wider in the shovels and tails, while maintaining an identical waist width (97.5 mm) as the previous Bonafide.

By slightly widening the tips and tails of the Bonafide, a bit more sidecut is created, and hence, we see the stated sidecut numbers decrease from 21 meters (the sidecut radius of the previous 180 cm Bonafide) to 18 meters on the new 180 cm Bonafide.

Rocker / Camber Profile

The number that jumps out the most is that the new Bonafide gets 1 cm more tip splay over the previous Bonafide, while the tail splay remains nearly identical.

The second most notable thing is that our review pair of 17/18 Bonafides has a noticeably diminished amount of traditional camber underfoot compared to our 16/17 pair. I wouldn’t expect this to create a dramatic difference in terms of on-snow feel or performance, but it’s worth pointing out.

Finally, before anyone gets upset about that additional 1 cm of tip splay on the new Bonafide (I might primarily be talking to myself here), it should be said that the tip rocker line is quite similar on the 17/18 Bonafide and the 16/17 Bonafide. So it’s not the case that the new Bonafide has been wildly rockered out; instead, it seems that most of that additional tip splay is occurring near the very end (tips) of the skis, and we’re fine with that — it would have been more worrisome if that extra 1 cm of tip splay was the result of a more dramatic amount of tip rocker that started deeper in the ski at the tip rocker line.

Flex Pattern

So what about the flex pattern? Did that change?

Here’s how we’d sum up the flex of the 17/18 Bonafide:

Tips: 6.5-7
Shovels: 7.5-8
In front of Toe Piece: 9-9.5
Underfoot: 9.5-10
Behind Heel piece: 8
Tails: 8.5

On the tails, any changes are pretty subtle. If anything, it seems like the shovels on the new Bonafide are slightly softer, as is the area behind the heel piece — at the tail, call it a 7 or 7.5 vs. an 8 on the previous Bonafide.

But the differences here are subtle enough that I don’t find it to be much of a story, or much cause for alarm. Blizzard didn’t neuter the Bonafide.


While the new ski is ~40-60 grams lighter, that’s a pretty marginal difference for skis of this width and length that are coming in around 2150 grams. So we don’t consider this a significant (or worrisome) difference, and you’ll notice that Blizzard doesn’t even mention the slight weight reduction. So let’s move on, and just hope we don’t end up missing those few extra grams when it comes to testing out the new Bonafide’s top-end.

Comparisons / Food For Thought

Despite the fact that Blizzard wants to talk about the “all-new” Bonafide, on paper, at least, the differences here are rather subtle. Thank god. So while our primary interest in terms of comparisons is still New Bonafide vs. Previous Bonafide, there are two other obvious comparisons to bring up: the 17/18 Bonafide vs. the 17/18 Nordica Enforcer 100 and Enforcer 93.

So if you like, you can check out the specs on those skis and read our reviews, and we’ll be back soon with our on-snow evaluation of the new Bonafide.

Bottom Line

“Easier to ski” and “more versatile” — that’s what Blizzard is claiming they’ve done — and all that they’ve done — to one of our favorite skis.

Stay tuned to see if we agree with them.

    Meaningless specifications run down and all the real test skiing impressions will be pushed behind the paywall. This is the new Blister.

      Hi, Alex – I know it’s fun to be snarky on the internet, but your claim is simply false.

      Those specs are far from meaningless, especially since you can’t find the actual, measured, verified, differences and distinctions between last year’s Bonafide and this new one — and Blizzard is calling this the “all-new” Bonafide.

      We actually take the time to make that information available – and provide rocker profile pics – when no one else does. So *you* might find it meaningless, but thousands of skiers disagree with you.

      And for the record, this all takes a lot of time. So we put out our First Looks to get this initial information out there, then that buys us more time to formulate our on-snow, full reviews — which are also very time consuming — and also free, just like our First Looks.

      So between our First Looks and full reviews, we’re giving you about 4000-5000 words on a ski for free, and we will stand by the accuracy of that free information.

    Ditto on Tanner’s comment, and thanks Blister for your review “culture”. The research, development and testing of today’s off-the-shelf skis is largely consumer driven, and we need a shared quasi-technical vocabulary such as is found in Blister’s reviews. Effectively publishing and utilizing this vocab requires methodology and documentation over a few seasons, to say the least. When a proven expert ski I enjoy is tweaked in it’s design, I want to know, as these changes will make significant differences in some areas of performance. I appreciate (and can “feel”) the careful comparisons made by Blister – both when I’m on line (in the abstract) or on the mountain (in application). I may not always share the exact conclusion as a Blister reviewer, but that’s just me and my technique preferences. Blister has dramatically raised the bar for ski reviews. Only very recently have one or two other review sites upped their game beyond the typical “good-better-best” product endorsements which here to fore were the industry norm.

      Thanks, Peter. I think another important additional piece here is that skis aren’t cheap, so unless you’re filthy rich or you just don’t care, then it’s meaningful to know what you’re about to drop hundreds of dollars on.

    Looks like the additional tip splay accounts for the reduced tip-to-tail length. I seem to remember some promo material stating that the effective edge is actually (slightly) increased. Probably not a huge difference there in any case. Tweaking of the sidecut is probably more important, but we’ll have to wait for the on the snow testing for the real impressions.

    Thanks for listing all the verified data, and the profile pics!

      Hi, Konsta – that assumption in your first sentence is correct.

      I haven’t seen any material re: effective edge, but when A/B-ing the two skis on snow, I never found myself thinking that the new Bonafide felt like it had more effective edge than last year’s. More to come…

    Hello Blister, I just wanted to reiterate the praise of fellow posters. Your articles are extremely insightful and have been a large reason as to why I recently purchased the 2016/17 Bonafides. Your reviews were instrumental in my decision making and I could not be happier with my choice of ski for my daily ride. I spent a week on them here in Australia and loved them. I was somewhat unsure whether they would be ‘too much ski’ for me, but they elevated my game to another level and they let me rip through all conditions. So thank you Blister and keep up the excellent work. I look forward to spending hours flicking through the next buyers guide…..Jonathan, I hope your recovery is going well.

    first I want to say ‘Thank you!’

    You are one of the only and definitely the best review page out there. Not having to guess a ski’s weaknesses by counting what was praised the least, is a blessing! Thanks for providing such extensive resources to choose skis!
    I just have one question about what you’re expressing with the often used phrase ‘more ski’?
    I read it repeatedly (admittedly, not in this review) and am never sure how to 100% interpret it. I’m just unsure if you’re referring to a higher top limit and more capability, higher technical requirements, higher demands in muscle power or something entirely different. I’d be happy if you could elaborate what this term means to you and how you use it.

    Cheers Rico

      Thank you, Rico. And as for “more ski,” that is short hand for a more “substantial” ski — a ski that offers more stability at speed and in variable conditions. And it almost always implies a heavier ski rather than a lighter ski – and heavier often means that the ski will feel more planted / stable / damp.

      I’ve never really met anyone who has liked skis that are more work / require more effort — more work / more effort is rather the reality of heavier / damper / more stable skis. They require more effort or strength, but if you are willing & able to provide that effort and strength, the resulting ride quality of “more ski” can be pretty great.

      So the question then becomes, How much ski is too little for how and where you like to ski? How much ski is too much for you? And how much ski is enough for you?

    I too find the First Looks very valuable. Yes, it’s only half the information, but very important. For example, last year my complaint about the Bonafide was the turn radius was too long and the ski wasn’t as playful or seem as quick as the Enforcer. The increased sidecut will address this, and less camber will probably also help. But, thankfully the stiffness seems to have been left alone. It appears the goal was to make the ski a bit more like the Enforcer. If they can do that, without losing the famous edge hold or all the other attributes Blister highlighted in the 16-17 version, the new Bonafide will be a winner, maybe even better than the Enforcer. I’ll be looking to see if the review shows a gain in liveliness, quickness, playfulness without losing the strengths from last year or if the strengths are gone without picking up any new benefits. Only Blister gives enough information to get these sorts of answers in a printed review.

    The “vague” feeling Jonathan cited in earlier model of the Bonafide was banished entirely from the 2016-17 model, and I concurred with Johnathan’s “perfect” characterization of the ski. It’s a truly great ski for my everyday ride.

    However, late last season, I wondered “WHAT IF the Bonafide was a tad easier to bend and had a tad tighter radius”? Sounded too good to be true. Now various reviews and hype indicates that Blizzard may have indeed nudged the Bonafide in that direction without sacrificing performance. Needless to say I’m looking forward to Jonathan’s in depth review.

    To speculate about the new Bonafide, it would be a shame (IMO) if Blizzard was attempting to incorporate characteristics of the Enforcer 100 into the R & D of the Bonafide evolution. After a demo last season, I concluded that the two skis are suited to very different techniques. For example, on packed piste, the Enforcer 100 has a lovely and precise turn shape, a buttery ride with solid rebound, and amazing glide for a 100 mm ski. However, the Enforcer had much less a “usable turn shape” compared to the Bonafide (even the early model Bones). Although the Enforcer’s shovel will engage and flex into the turn early enough, the front of the ski only begins to effectively carve when the entire ski is bending into the turn shape. Conversely on the Bones, the shovel and front of the ski can be energetically driven to define the turn shape. I felt like 15% of my turn efficacy just disappeared on the Enforcer 100. (Perhaps I should have demo’d the Enforcer 93.) This edge loss on the Enforcer could be partially mitigated by exaggerated angulation and adjusting my stance aft to get onto the middle sweet spot sooner, but it felt weird to be riding the front of a ski which was so ineffective. And, in the worst case scenario, on very icy conditions the Enforcer 100 felt almost like a beginner ski.

    Perhaps recreational ski design development is defining itself in into two basic camps; ski’s for those who typically use the entire edge length, and ski’s for those who typically use much less edge length.

    Hi Jonathan. Thank you for your in depth and insightful reviews.They point midwesterners like me in the right direction, as we do not get much demo time until we make our annual pilgrimages west.

    Do you have the same thoughts towards the 17-18 Bonafides that you cite below for the 16-17 in terms of the 180 being a sweet size for this ski and stable enough to handle larger skiers at speed? Im 6’3 205 and have been skiing for 30 years. Currently skiing 14 Mantra’s at 184 for my western dd and 16 Faction Candide 3.0s at 192 for open soft conditions and powder up to knees. I like both of my skis for the right conditions but Im looking for a ski that is more suited to trees and bumps at resorts like Winter Park and Steamboat. That said, I still want to be able to let it go on open terrrain and ski all conditions short of deep powder. Im leaning towards 180s but a little concerned they will be a little squirrely over 50 mph with my size. Any thoughts will be appreciated.

    “Jonathan Ellsworth, Editor-in-Chief, Blister October 4, 2016 Reply
    Honestly, I am inclined to tell you to stick with your 180s. Basically the entire gist of the update I need to write to this review could be called, “An Ode to the 180 cm Bonafide.” It is just such solid performer, and it is not a difficult ski to ski. So you get a powerful platform but with all the advantages of a shorter length ski. At a super moguled up ski area, that is a great combination. I liked the 180 so much, I made my good friend Mike get on our 180s. Mike weighs around 240, and he skis hard, and he never skis on anything this short. And he came back and couldn’t believe how capable the 180s felt. And again, I’ll stress: capable without ever feeling difficult. So that’s just 2 guys’ opinions, but if you are at all concerned or on the fence about which length to get … this is a time where I feel fairly confident that you can go shorter and end up with a solid, stable — and quick — ski. I love this ski.”
