Hello and welcome to my Flux SR bindings review.
In this review I will take a look at the SR as all-mountain-freeride snowboard bindings.
As per tradition here at SnowboardingProfiles.com I will give the SR a score out of 100 (based on several factors) and see how they compare with other all-mountain-freeride bindings.
Note: This review has not been updated since the 2020 model
Note: The Flux SR are quite soft flexing and I would normally rate these in the freestyle category. This category is usually reserved for those bindings with a 6.5 to 7.5 flex. But I decided to include the SR here since Flux describes them essentially as "powder" bindings. I don't have a separate category for such, so I chose this category. However, since they don't fit nicely into any category, they don't rate as well as they might had there been a dedicated "surfy powder" category" or something like that

Who are the SR Most Suited to?
The SR are a great choice for anyone looking for a soft flexing (but not ultra soft), surfy feeling binding, but one that's good quality and well built.
Beginners could ride this binding too. It's easy going and easy to ride with and matches well with medium-soft flexing boards.
The SR in More Detail
O.k. let’s take a more detailed look at what the SR are capable of.
Demo Info
Bindings: Flux SR 2020
Size: M
Date: April 14, 2019
Conditions: Great vis first thing but started closing in and then snowing 10:30. Then on and off throughout the day. But vis was never terrible – in patches good and in patches OK.
Groomers were quite smooth and fast, especially compared to the day before, which was nice.
Nothing crazy in terms of fresh snow, but 1cm (0.5") overnight and few more than that in the days leading up - some fresh patches still to be found.
Relatively cold with a little wind, but not much - wind not as strong and not quite as cold as the day before. -4 with wind. Still pretty cold for April 14th!

Bindings angles: +15/-15
Flex
They're not like ultra soft, but they're a little softer than medium. 4/10 is pretty accurate, by my feel.
Responsiveness
Not the binding for elbow deep carves, but for a surfy feel and in terms of maneuverability at slower speeds, they're really good. Great for those tight situations through trees, weaving through bumps etc.
Board Feel/Butterability
The SR don't have a mini-disc or anything like that, but they're board feel is very good. I would say that's at least in part to do with the minimal thin foot bed.
Adjustability
Heel Cup: No
Stance Width: You can run the disc vertically or horizontally, so if you run it horizontally, then you get good stance width adjustment
Highback Lean: Yes - tool-less
Ankle Strap Position: Yes
Ankle and toe strap length: Yes (tool-less), though I haven't seen a binding that doesn't
Gas pedal/toe ramp extension: Yes
Highback Rotation: Yes
Compatible with: 2 x 4 | 4 x 4 – need a separate disc for channel mounting
You can adjust these bindings in most ways. You can adjust the heel ramp too, which you can’t on most bindings, so that gives you some extra adjustment there.
Shock Absorption
Pretty minimal. Thin, hard footbed. This has it's advantages but not great for chatter or shock absorption.
Entry/Exit
One of the smoother ratchet systems in the binding market.
Comfort
Really comfortable all round. Only thing is that lack of padding underfoot, but otherwise, the ankle and toe straps are very good (typical of flux) and the fit around the boot is really good.
Ankle Support
Really good ankle support. Not quite to the same level as other Flux bindings - but these are meant for surfy riding, so I think it's done purposefully on these.
Score Breakdown and Final Verdict

RATING | Contribution to Final Score | |
---|---|---|
RESPONSE | 3.0 | 18/30 |
BOARD FEEL | 4.0 | 12/15 |
ADJUSTABILITY | 4.5 | 13.5/15 |
ANKLE SUPPORT | 4.0 | 12/15 |
SHOCK ABSORPTION | 2.5 | 5/10 |
COMFORT | 4.0 | 8/10 |
ENTRY/EXIT | 4.0 | 4/5 |
TOTAL after normalizing | 77.1/100 |
If you like to surf the mountain and like a softer binding, but still want a well built binding with a quality baseplate and quality straps, then the SR is a great option. Higher end bindings are typically stiffer flexing, so the SR is a rarity, in terms of it's flex and quality combination.
Could be used as beginner bindings too (all be it pricier ones) or for playful freestyle riding.

Hi Nate,
It looks like you have ridden Flux in both M and L in size 10 boots. Can you comment on their sizing?
I have 9.5US Ride Infuses, which would be closer to a 10 for most brands. I prefer more heel over hang than toe. The boots fit well in Medium Unions with the heelcup pulled all the way back.
I am considering the DS but not sure if I should do M or L
Hi Jared
Thanks for your message.
Can you clarify if you mean Ride Fuse or Vans Insfuse? Either way, I think they’d likely fit in an M in a 9.5. I had no issues fitting my Vans Aura 10 in the M, though they are relatively low profile both in terms of length and in terms of the height of the toe box end. The Vans Infuses that I’ve measured are just as low profile as the Aura – though with a little bit of a higher toe box, but I think they’d still fit in a medium. I haven’t measured a Ride Fuse, so I’m not sure specifically, but most ride boots I’ve measured have been quite low profile (in saying that it does depend on the individual model sometimes), so I would suspect that the 9.5 Fuse would be fine.
However, given that you like more overhang on your heel, I think Large is probably the way to go. I’ve never had any issues in Large, with size 10s. With 9.5s, it’s a little smaller, so couldn’t say for sure, but I think you’d be fine, particularly if you want that extra heel overhang.
Hope this helps
Thank you Nate. Yes, I meant the Ride Fuse. With the spine of the boot against a wall, it measures 31.1cm but the sole itself is about a half cm shorter.
Fixed heel loop bindings are always tricky to size. K2’s in large fit my boots perfectly. With Burton the mediums were always a touch small and larges too big.
Hi Jared
That is really quite long for a 9.5 (though our measuring techniques might vary). Still I think Large is the way to go even more so now. Yeah, definitely easier to get that boot centering with an adjustable heel loop for sure.
