Product outline: Huck Norris anti flat tubeless protection is intended to provide additional protection to your tubeless wheels and tyres to prevent pinch flats and does it in such an easy method by providing a foam insert that creates a pillow of sorts between your rim edge and tyre when your tyre sidewall is compressed.

Pros: Very light, very easy to install, very effective at preventing flats, makes it easier to inflate a tubeless tyre with a floor pump, buying the two wheel pair comes with packaging that doubles as a mudguard!
Cons: Absorbs tyre sealant.

Fitting: First up, ensure you order the correct width Huck Norris to suit your rims and tyres. I've installed Huck Norris on a 27.5" wheelset with a Stans Flow EX rim that is 30mm wide internally. The guideline for ordering Huck Norris is to get the one that is wider than your rim measurement so in this case I ordered the large size to suit rims 34mm to 45mm. I ordered the set too, it comes with two pieces of Huck Norris to do a front and rear wheel. It's important to note that you need to trim the length to size and it comes to suit anything up to a 29" wheel so no need to look for something that suits a smaller or larger wheel.
Fitting was totally a breeze. My method was simple. I unpackagaed the Huck Norris, let them sit on the ground to unfold and sucked the existing sealant out of my wheels using the Stans syringe. I then popped the tyre off the bead on one side, gave it a quick wipe inside with a clean towel and grabbed my first piece of Huck Norris. The idea of it is to sit between your beaded tyre where it meets the rim face and the underside (inside) of the tyre tread so when you roll over something sharp edged (a rock) or land hard (huck to flat) your tyre will not be damaged by the rim edge because there's a fancy piece of Huck Norris between the two surfaces.
With that in mind, you simply roll the Huck Norris around the outside edge of your rim and locate the first spot that will indicate where to cut the material. Hold up folks! The old saying of "measure twice, cut once" comes out in force here, make sure you leave enough play in the Huck Norris that it isn't too tight on the rim edge! Once you're sure that you're on the right spot, you mark the line you want to cut off with a sharp blade then double check it. You need to make sure you keep one of the joining tabs that run across the pattern of the material as this surface will butt up again the other end of the Huck Norris.
Now, cut it cleanly so the short side edge will sit flush against the opposing end, just to be sure it will sit snug. You then roll the other end so it is against the piece you just cut and you wrap the provided velcro strap around the two ends. I suggest using some clamps here, I have clamped the two ends together then put the velcro on to ensure it sits firmly, OCD maybe? ;)
This is the point where you can sit the Huck Norris inside your tyre and above your rim edge. You'll see just how well this setup works at this point and you'll understand why the correct measurement is crucial. It should just slide straight inside your tyre and not drop inside your rim edge and lean over the rim edge below the seated tyre surface on the other side.
Right then, this is where you can insert your tyre bead into the rim and seat your tyre. Pay some attention to where the Huck Norris thick edge sits as you seat the tyre as it seems like it can roll to one side and not be in the exact middle of the width of the tyre. You'll notice it should be pushing your tyre sidewall out and making it easier for your tyre to seat. Once the tyre was on, I rolled the wheel along the ground with a deflated tyre and made sure I could feel the Huck Norris between the underside of the tread and the rim edge, that way I knew it was in the right spot and it was actually super easy to line it all up. You'll get the best feel and impression for what Huck Norris is all about at this point too, you'll feel that magic cushion between your tyre and rim edge and your confidence should grow!
The next step is to put your sealant in. I use the Stans syringe that feeds the sealant in through the removed valve core but you can just put your scoops in before you bead your tyre if you don't do the core method. My advice though? Get a valve core removal tool, grab a sealant syringe and never spill another drop of sealant on Nan's rug again. ;) I tend to put around 120ml of sealant in but this time around I put about 160ml as the Huck Norris suggests it soaks it up a little as it has more surface to cover, makes sense.
Now is the point where you can test the theory that Huck Norris makes it easier to inflat a tubeless tyre with a floor pump. Science says it should too, the material pushes your tyre bead into the rim and should just seat itself............and it does! It was a breeze to inflate from zero pressure to 40 PSI and the bead seated itself at about 20PSI. To my liking was the fact that it was a brand new tyre too. ;)

On the trail: My timing with Huck Norris was planned. I installed it a week before I was due to fly out to sunny Queenstown in New Zealand and shred the beautiful loam, the round edged roots and the square edged rocks of the surrounding mountains. I've spent many a summer in New Zealand and have never come home without flatting tyres on trail bikes, enduro bikes and downhill bikes both tubeless and tubed. I was so confident in the science of Huck Norris that I knew I could rely on it to prevent flats. Did it work? Yep! Not one flat, only typical PSI deflation of around 3 to 5 PSI a day, no burping, no loss of sealant and no holes. Did I actually man up and try to pop a tyre on a flat landing? Did I line up every root or hard edged rock and totally smash into it? Well, yeah I did but those that have ridden the hills around Queenstown know that you can't avoid them anyway and your only option is to smash into it all!
You know that dreaded ping sound when you hammer into a hard rock? I have forgotten that sound since putting Huck Norris in my tyres, not a sound! Surprisingly though, the anti flat protection isn't the only upside I found to Huck Norris. read on.............
Huck Norris has totally changed my tyre feel. It has eliminated a shitload of sidewall roll and firmed the tyre tread surface up so my grip is more predictable than ever. Having that tubeless feel with a horizontal stiffener inside the tyre has made my ride feel really stable both in cornering and braking. I don't tend to run lower pressures purely as I like some extra feel in my tyre but Huck Norris has allowed me to tinker a little with what I'm used to and broadened my view on what can be achieved with performance on your bike through some squishy bits.
I did not notice any extra rotational weight, I didn't feel heavier on some of the 1000m vertical climbs and by the second day I was totally confident that I could go that little bit harder into some features knowing this material would hold the wind in my tyres.

Summary: Is it just a gimmick like a Power Balance Band? Did some Astrology guru dream it up and is making millions from it? I dunno about the latter but can assure you that if you have ever had a tubeless flat then Huch Norris is a deadset savior to your existence. It's cheap, it's so effective, it's so easy to install, it's simple technology that just works. You can ask yourself "Yeah righto, you didn't get a flat so how do you know it works?"..................I have gotten heaps of flats but with Huck Norris I have had not one issue with anything relating to tyres. It works for me and I'll be putting it in each wheelset I have on my rides. Honestly, I cannot see a downside to it.

This testing suggests HN may be no advantage for pinch flats (@5.54min in clip).

https://www.pinkbike.com/news/weve-got-questions-digging-deep-at-enve.html

No indication of tyre pressure but assuming same was used for all testing, relative outcome.

Not sure how analogous to real world performance.
Thats a cool video, nice to see them sharing their story a little.
As for the Huck Norris, I'm not sure that the video says much about that type of rim protection either way. The Huck Norris obviously had split in it but they didn't say the rim did or didn't crack and they didn't say the tyre pinched or not. It also looked like they had a narrow version of the Huck Norris installed but it still made contact, only just though. ;) They did say they were surprised at the result though, hopefully we get some more text on it even.
Thanks for the share. ;)
 
After some mild persuasion from Markee I just removed the Huck Norris that I had in the back and have fitted a Cushcore. The allure of super low pressures and ridiculous grip were too hard to ignore.

In terms of fitment I found it quite easy. Flow MK3 rim and DHR2 Exo. I left one side of the tyre mounted, fitted the Cushcore and then got the other side of the tyre on using a gentle pry from a lever for the final couple of inches. The ease was rather an anticlimax as I was preparing for a 30 minute long round in a cage fight.

BTW I weighed the Huck Norris at this point and it had increased from 80g to 120g as result of all the sealant absorbed onto/into it.

Will report back to advise whether the swap was worthwhile.

Thats good to know, thanks for the info. Was the sealant noticeable on the Huck? Was it dry and flakey or absorbed and still kinda wet even?

The whole thing was soaked with sealant. I don't believe it was soaked through as it is a closed cell foam, but the sealant certainly was clinging to every little pore that was in the outer surfaces. I'd already topped up the sealant once since I installed the HN so I guess it probably wasn't just imagination that the wheel was getting heavier lol.
 
Quick update now I've put a few rides onto the Cushcore.

I am running 4psi less than with the Huck Norris and not feeling excessive squirm. The first few runs I kept thinking I had a flat tyre because the back felt kinda "dead". After I got used to it, that feeling translated only into very high levels of grip.

It was a case of re-learning what lines I could take and at what speed, as the rear would no longer ping off stuff and bounce me off line. I'd have to say the feeling is like when you first fit a coil shock. I also lowered my front tyre by 2psi as well to even it up a bit (not running any sort of protecftive strip). So front is 20psi, rear is 22psi now, 69kg ready to ride.

Didn't really notice the extra 130g over the Huck Norris to be honest. I imagine if you are riding a very light bike or doing a lot of mileage it might be a different story.

I think both products fill their respective niche well. Choose HN if you want a reasonable amount of protection for the rim and sidewall but with minimal weight and cost. Cushcore if you want to be able to run very low pressures, have a nice damped feel to the tyre, and very high level of rim/tyre protection, but can cope with the extra 120-160g (compared to the HN) and about double the cost.
 
Ghetto fix warning.... This is not for everyone and some maybe unsure about this. Try for yourself and I'm not guaranteeing anyone else will get the same results.

Ok, for those of you, like me who are curious about this and want to see if Cushcore or something similar is for you without emptying $250 per bike on them here's an alternative. And yes it works as I've tried it.

Stick with me on this, don't scoff or laugh until you've tried it for yourself.

Nip down to Bunnings and head to the plumbing section.

There's three types of black foam pipe insulation there so pick 2 sections of the 19mm internal tubes for each wheel you'd like to do. It's soft but compact and dense, nothing like a pool noodle.

Super glue the two tubes together to make one larger ring. That ring will fit nicely into a 27.5" or 29" wheel. I've tried both. One 21mm internal XC wheel, another 30mm internal trail wheel.

Pop one side of your tyre bead and insert the tube. Keep your sealant in there.
Mount up the other side as normal and inflate to your desired pressure.

I tried it just out of curiosity and it's quite amazing.

1. The bike is super quiet. It seems like a lot of the noise a bike makes is stuff hitting the tyres and the noise reverberating and amplified by the space in the tyres.

2. Comfort. The ride is very muted now, the trail is calmer, especially choppy bits.

3. Tyre support. I've run lower pressures and felt none of the squirming I'd normally expect.

4. Rim protection. I was tired at the end of a ride and didn't lift the wheel enough over a kerb, I heard a dull thud and stopped to check, no damage, mark or anything.

5. Weight. You can definitely feel the weight increase. I'm reasonably fit and strong but notice this on climbs. I still made it up everything, it's just more effort. You also feel more momentum downhill.


Watch outs.
1. Don't get tempted to go for the super fat insulation. It'll fit but it weighs too much.

2. You have to super glue the ends together otherwise it overlaps under pressure and gives uneven protection

3. If the valve fitment is too close meaning the tube interferes with letting the tyre down just remove the core and use an Allen key..

Is it as good as Cushcore? I don't know.. the described sensation seems to be what I'm experiencing. It might weigh more, not be as durable or offer as much protection but the difference is real and quite distinct.

If you're on the fence and want an indication of what it's like, it's a low cost, low stress and easy trial. Cushcore clearly will be better given the purpose built design and engineering.

Oh, the cost? The tubing costs $4.00 per length...
So including the glue each bike cost ~$17.00 to do.

The wheels are still inflated, spin perfectly.
Mods. Feel free to move this post as you see fit if it shouldn't be here...

And please don't flame me for this.. you're free to do what you want with this and your bike. I'm only telling you what I experienced.

Good idea to at least try before you buy the real thing!

K-flex 9x19mm from bunnings. Is that the stuff?
 
Closed cell Polyethylene tube might be the go. About 39c a foot. Should be lighter than the insulation. I'm going to try it tomoz. Fucking love ghetto shit that works.
250 for cushcore. Haha
Yep, there's bound to be more than one option.
The best thing with the pipe insulation is two glued together fits both larger sizes of wheels without cutting or trimming. Too easy.

And use super glue. I found other glues didn't hold well.
 
How does this stuff go with compression and protecting the rims?
It's been completely fine. The material compresses well and retains its structure and form.

It also has a lovely damped feel to it so it absorbs impact. How durable it is over time is in question so I will monitor it in the coming weeks.

It's wide enough to provide ample coverage for my 30mm internal width rims.

I also tested it before installing by putting it betweem my rim and the garage floor (albeit with a layer of carpet) just to see how it handles impacts. It was fine and the rim didn't cut through it.

Just bought the kflex foam from Clark rubber. I went 13mm as my rims are 24 internal and when the foam flattens it will be well sufficient to protect. The stuff is quite light too. Fuck you gouging Mtb industry. Thank you Gods own Reverend

Keen to see how you get on with it... Hope your experience is at least as good as mine.
 
Just fitted it. I glued and also used a little packing tape around the join to strengthen it. Be nice to run low pressures again! Only did the rear but I'll buy some more and do the front tomorrow. Quick spin with low pressures and it works. Too bloody easy

Any pics during installation?
 
IMG_2217.JPG IMG_2225.JPG IMG_2226.JPG Glued and taped two pieces together, weighed it, put it in the the tyre, poured in sealant, floor pumped it up...Done. now running about 23 psi. 13mm will be like huck Norris, 19mm like cushcore with support.
