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.

Good work there mate. Especially with the photos and weights. I just put them in and went riding.

How did you feel the bike ride afterwards?
I only rode around my streets looking for roots and square edges, worked on them. The 13mm won't have much for cornering support like the 19mm, I'm certain it will be great for rim protection. I'll test it out tomorrow properly.
So good

Cool. And with the price and ease of installation you can try the 19mm version too.

And yep, Rim-Rambo, $99.99 Inc postage (I've got a soul!)
 
Works awesome. Love being able to run low pressures and just crash through anything. Tyre squirms at the back a bit but it is an ardent race. Rolls so much quicker and at 80gr plus 50ml sealant it's lighter than my tube.
 
I gave my 29" a proper run today and it's even better than the 27.5". What I thought was wheel weight was actually just the geo of the bike on my 27.5" relative to my 29" as I'd been on the Fuel last.

On my 29, whether it's the wheel internal width being a bit narrower, or something else but it rides superbly. Best mod in ages for me!
 
Just set up my Strive with this ghetto rim protection. Super cool

Cost is 2 x $5 per wheel. Set up was easy, similar to putting a partly inflated tube in.



I’d been given a top tip to help the valve work with Cush core and the like and so cut a groove in the valve with a dremel to allow air to pass



Will go for a short ride in the morning to see if I can start to dial in a sensible air pressure.

Nice one. Start off sensible and go from there. The sound / feeling is so very different!

Nice work! Have you got a before and after shot of the valve?

Also which piping did you use?

Haven’t got a picture of the valve before hacking into it

Pipe is K-Flex 13mm x 19mm and comes in 1m lengths. I needed pieces per wheel stuck together with super glue



This is the piece I needed to chop off for it to be the right size on my 650b wheels. I measured it against an old wheel I had spare in the garage.

I feel I should offer a bit of a story as to why it's worth supporting CushCore in their endeavours.

I did my pre-order through Defcon in May 2017, and I still had outstanding units that hadn't been delivered when they liquidated in November, after multiple contacts with Stuart. After they went out, I told CushCore (who I'd been in contact prior to my pre-order and throughout the process), and they filled the outstanding order from their US store when they heard what had happened.

I know it seems expensive, but they have done a super polished, high quality, well thought out product, and they are a really good bunch of people. The kind of people that I'd be willing to keep supporting.

What you've done looks very similar to Flat Tyre Defender... The only proof will be how well your material holds up to repeated impacts and exposure to sealant.

I hadnt seen the FTD. Looking at it the foam type seems the same but the K-Flex pipe insulation has the 19mm hole through it which the FTD doesnt seem to have.

The hole could be good or it could be bad. It could certainly be a sealant trap :/

Hey Zaf,

I get and respect what you're saying. In my view this is not meant as a direct replacement, more an intermediate step and possible indication of what CC and the like offers.

It may not last as long or be as protective as CC.

For many, myself included it's a lot of coin across multiple bikes to test if you're not happy with outcome... This might help bridge the gap.

I’ve just checked the spec sheets for the material. It’s an elastomer and doesn’t absorb more than 1% of its weight in water so seems good for starters

I’ve looked as a variety of back to back tests with Cush core, huck Norris and FTD now and it will be interesting to see how well my garage made version holds up and prevents punctures.

It certainly won’t give the anti burp benifits of Cush core, it’s not anywhere tight enough but it feels a lot lighter and is certainly cheaper

Looks like a Banger by Mr Wolf.
 
The plumbing store I work in has K-Flex in 2m lengths, and that will save you a join. We also sell it for about $6 or $7 a piece to, so try around before you head to Bunnings!

How'd the ride go?

I made up two wheels using 13x19 thickness (26 inch wheels, 25mm ID, F - Magic Mary 2.35 , R - DHR2 2.3) and just from looking at it sit inside the tyre ... I can't imagine there being much room for sealant to spread easily in between the K-Flex and tyre.
Though I don't have the K-Flex wrapped tight against the rim, its a tiny bit loose.

May have to go to the smallest size (start sensible hah) and see how that goes. By the looks of it, that'll perfectly sit on the rim with a little bit extra over the edges.
