Huck Norris


Occasionally, an idea comes across my desk that makes me scratch my head and utter, "Why didn't I think of this?" Huck Norris is one of those. Invented in Finland, Huck Norris is a circular band made from closed-cell plastic foam that is cut to fit inside the widest part of a tubeless tire casing. The band weighs less than an inner tube and, because it does not cling to the entire circumference of the tire casing, it allows a tubeless tire to remain supple and does not impede its superior rolling resistance and traction.

The potential benefit of the Huck Norris band is reaped when impacts that are normally severe enough to bottom the tire onto the rim flanges and produce pinch flats, sidewall cuts, or dented rims - are cushioned by the foam band and rendered inconsequential. But wait! There's more. An unexpected benefit of Huck Norris protective bands, is that they spread the beads of tubeless tires apart, which allegedly makes even the most difficult rim and tire combinations mount up easily with a simple floor pump. The bands are available to fit 29, 27.5 and 27.5+ size tires, and cost 69 Euro at the Huck Norris web store. Read the Huck Norris press release below.

Huck Norris anti-pinch-flat bands 2017
Upon impact, the Huck Norris band is squeezed between the tire and rim, acting as a shock absorber, which reportedly prevents pinch flats and rim damage.


bigquotesHuck Norris is the fellow inside your tire to fight off the Bruce Leaks. It also scares off snake bites and nasty dents. He's your buddy to inflate the tubeless tires, giving extra kick to the tire when you want to punch it on your rims. - Huck Norris PR



Huck Norris joins the fight against pinch flats!

We got fed up replacing our tires before they actually wore out. Also, we got fed up ending our race runs with flats. We do racing because it’s fun, and racing on flat tire isn’t fun anymore. We think that in the year 2016 riding should be puncture free. We have seen even the pro racers ending their race runs with punctures. This is something what should not be possible these days with modern technologies present. We wanted to take the bull by the horns and develop simple solution to prevent punctures. In the end we realized that we have resolved a bigger issue - the hassle of inflating tubeless MTB tires.

Huck Norris is a cellular foam which goes inside your tire. It sits in the middle of the tire and touches the sidewalls only a little so you don’t miss any of that sweet rolling ability of your tire. When you are about to get a puncture, the Huck Norris is between the tire beads that are folding together. Huck Norris creates an extra cushion to your tire. This protects your rims and your tires. The good thing is that you don’t need to modify the rim or the tire. It’s an affordable solution to make your rides longer and save you money.

Have you tried any fabric protection spray / coating to prevent the sealant absorbing?
  • + 2
 @lordchewington: Thanks!
That is an interesting idea, we have not thought of that. Need to look into it, even though the sealant absorbing is much less of an issue than what it appears here. It is closed cell foam, so material is taking in about 2% of liquid, which in practice is next to nothing. I personally don't put any extra sealant because of that. At he moment Huck Norris is water cut to shape and that leaves open tiny amount of those cells, we have planned trying to do the cutting with laser and seeing if that could melt the material so that cells would not be left open. Not too much in a hurry with that though, this is still very marginal improvement.
  • + 1
 @Prestige: cool as. Yeah a laser might be worth a try. How can I get a wide 27.5 for my 35mm I.D rims?

 @ChampionSleeper: Three times the pipe insulation stuff you can get from hardware stores. Sorry no numbers to publish at this point, we are working on it. Current version is measured with classic drop the weights on it methods. It doesn't give very good compressive strength numbers, at least with our skills in physics, but represents the real life situations better.
  • + 1
 @Prestige: Better watch out with the hyperboles. There's a big difference between 'anything commerically available' and 'the pipe insulation stuff you can get from hardware stores'. What material is the foam made from? Does it resist long term exposure to ammonia in sealants? Can I just spray brake cleaner on it if I want to get rid of dried up sealant?
  • + 5
 @Prestige: Alright, I'm guessing you are using 1/2" thick, 4 lb density polyethylene (closed cell), which is compatible with propylene glycol (Stans). I did the math on the weights provided in the article and this looks a pretty close match. A single 24" x 108" x 1/2" sheet retails for $22 online. Using that, I could cut 10-12 strips at a cost of $1.80 each. Unless you help us understand why your material is better, I can't imagine spending $77 (43X$1.80) on a single rim strip. Granted, your product might be 15% lighter, but not worth an extra $75.
  • + 3
 @ChampionSleeper: $1.80 materials, $3 cutting, $1.50 packaging, $1 warehouse/freight, $3 marketing/advertising, $1 R&D, $2 sponsorships, $20 profit, then 100% store markup. It's a lot cheaper to DIY, and steal other people's ideas. If the HUCK Norris kids can't figure out how to properly patent this then you should be able to buy the copied strips from a bigger company for &30.
  • + 2
 @unrooted: I can buy a decent set of Shimano Pedals for $80. In fact, almost any other component on a bike can be had for $80 or less other than a fork or shock. I understand manufacturer profit, and retail pricing, but there is still no way a strip of foam should cost $80.
  • + 13
 @ChampionSleeper: Wow, I'm impressed how close you got with limited information the available. We did go trough the effort of doing our best measuring how much impact different tires can take, and got the material to be just tiny bit weaker, so never should happen that the tire punctures before the material gives in. Density and thickness are not quite what you write, but those would be good place to start from. With your knowledge you should go for Hack Norris instead of buying from us.
The thing with the price though, we wanted to make it as affordable as possible, the issue is that it would be possible to make it cheaper if material would be made and packed in far east, but with our current resources we have no way of making sure that environmental things are considered in production and no kids are have to labor in packing the stuff. So we chose to have it made where we can check these things. I think for saving 10€ in your money, is not worth screwing up nature and kids.
  • + 3
 @Prestige: I just browsed through the datasheets available at foambymail.com and came to the same conclusion, so it wasn't that hard to figure out. I appreciate that you take people and planet into account but still 82 euros (including shipping from a store where I never order other stuff) is far more than I would want to pay for this product. The idea is neat though.

 Dude, do you even mtb?

Well, I guess a lot depends on where and how you ride. But where I live (Finland) it's more or less rocky everywhere and I run near 2.5 bar in the rear most times. Last time I tried 2 bar was coming off from an injury and I thought I would just take an easy ride. 10 min from the door and I accidentally took a line I wasn't supposed to and did a 3 foot drop on a rock and had a textbook snakebite on a 2.5" 29" Exo DHF and a dented rim.

So yes, I think these kind of systems make a lot of sense to a lot of people, not needing to run overinflated tires and suffer from bouncy ride and bad grip.

 @choppertank3e: it's the normal way to measure air pressure. Normal air outside is 1 bar. 2 bar means twice as much air in the tube than in the same volume would be outside the tube.

PSI stands for Pounds per square Inch. Even English people who invented imperial start switching to metric because imperial is a retarded way to measure. "That bike weighs one rock, two stones and a handful of sand. The toptube length is one arm length, 4 toe nails and 0.5 teeth long". I hope you see my point?

For my first two years riding this event I got about 5 pinch flats during the weekend even with exo sidewalls and 2.5 bar rear. But anyway, this is not a bulletproof system, more like a risk deducer. I've seen dented rims and flat tires on fb with people running this. But I've also got a friend who burped on a Deaneasy and another who broke a Procore getting the tire rock hard with pressure coming from the inner chamber.

 @jdendy: Second that. A wild run at south mountain would be convincing. It seems like the foam would put stress on a tire's casing when using a rim width smaller than 25mm, especially at 1.5 bar. A tire like a 2.5wt dhf and 30mm rim is probably remarkable with this foam.

 @eriv: the foam does not add any strength to the tire: it only softens the blow. It's like poking a piece of paper with a knife against a hard surface in contrast to placing the paper on a pillow and poking a hole. It may take slightly more force on the pillow, but the end result will be the same. Give me a thin sidewall tire and halfway down Geronimo and it will be toast.

 That's a lot of sealant he dumped in there; the foam soaks up the sealant maybe? And tubeless, you use that system because you don't get pinch flats with it, we were always told and sold that, right? Huck is confusing me, but I ain't gonna tell him...

flag cwatt (Aug 29, 2016 at 20:00) (Below Threshold)
 Yeah, I'm a little confused myself. How can you pinch-flat a tubeless setup? Also agree with the amount of fluid - not sure the lighter casing is enough to balance out the added weight of the fluid and foam. Perhaps a closed-cell foam would help let you run a normal amount of sealant becuase it won't soak it up. Lastly, I'd be more apt to running a Schwable ProCore which offers rim protection, provides a back-up tire pressure, and is lightweight.
  • + 24
 @cwatt: There's nothing lightweight about procore. Your basicly putting 2 tires on each wheel.
  • + 1
 @cwatt: I'm thinking that maybe something like this is the evolution of procore? Closed cell foam, and in a shape that protects the rim and more importantly fills up volume in the tire to make it more progressive to allow lower pressure. obviously wouldn't lock the bead like procore, but maybe could be cheaper/lighter/less finicky for some benefit
  • + 17
 @davidsimons, you can totally still pinch flat a tubeless setup.
It takes more work... but if you crush the tire against a rock hard enough it will hit the rim and cut the tire open in two spots, proper snake bite fashion.

The Stan's spluge will seal the resulting cut in the tread area eventually.
But it will never ever seal the 2nd resulting cut on the sidewall right near the rim.
You will need to throw the tire away. Run a tube indefinitely. Or patch it from the inside with a radial car tire patch before it can be run tubeless again.

(Yes, I've done it enough times to know exactly where the cuts will appear. *Sad face.)
  • + 4
 @LukeBurgie: based on the amount of sealant he had to dump into the tire I am pretty sure Procore is similar if not lighter than this product.

Not sure why they don't wrap the foam with some sort of plastic similar to a saran wrap. This would solve the sealant absorption problem and actually make more sense of the cost.
  • + 6
 @cwatt: procore is not good on most carbon rims as the extra pressure from the inner tube on procore can break the rim. Procore is also 200 grams, huck Norris is less then half that. The huck noris foam is closed cell but all the edges of the foam can soak in a little sealant, Because the cells are cut. And u can pinch flat your tire (not the tube) even running tubless.
  • + 2
 Procore weighs 200g over a standard tubeless setup. This weighs around 150g more (70g for Huck Norris and like 70-100g more sealant. It costs 1/3 of Procore which detonates rims as soon as you dent them.

 @jimmychoo401: I ran procore all last season. It's a pain in the ass, it fails constantly. I had to replace 4 of the proprietary procore tubes in 2 months because valves would break. And the extra 200 grams per wheel is very noticeable. I'd rather t-bag a bear trap than ride procore.

 I've split proper tubeless tyres on proper tubeless rims right at the bead because of pinches even when running reasonable pressure and they're usually a nightmare to fix, or aren't fixable at all, unless I'm doing something wrong.

 @WAKIdesigns: yep, absolutely, that's the one. To be honest I only ever really felt the benefit of tubeless when I went to Sierra Nevada in Spain to protect against thorns. Tyre pressures were pretty high and pinch flats rare. Back in Scotland there aren't any thorns but I got more pinch flats. I still get the odd pinch with the tubes but its a quick fix and without all the mess.

 @WAKIdesigns: I think he meant that too light is too light. Grid/exo reinforce the sidewalls but not the casing under the tread so they pinch flat. Rockr2 are fully reinforced not to mention their superior side knobs and rubber

 @won-sean-animal-chin: i personally find EXos TR meaty enough for local riding on natural trail. Once the lift time comes: Double Downs
  • + 1
 @WAKIdesigns: ya depending on the terrain and speed(lift speeds) exo might be fine but they seem to deteriorate quick. Doesn't take long before they get really flexy and weak. Minions are pretty good tread and have been the standard but after using the wr2 there's no way I'd go back to a minion. Wr2 isn't the quickest roller though so maybe something else out back. Wild gripr is ok but intermediate knobs are too close to side knobs. I've been meaning to snip a gap between those knobs
  • + 2
 Yup, too light is too light. I like tires that are stable under speed and won't flinch when you start slamming into square edge hits. Anything under 1000g doesn't last very long for me. Ditto on the never going back to Minions after trying a Rock'r. They really are game changing.

 @nvranka: No im not I just know a lot of workers from WTB that would also say what I said. A few ounces of stand liquid weighs less than a tube. The less rotational weight you have on your wheels the faster you coast, pick up speed, and stop if needed that much speed to be reduced.

 @nvranka @chillrider199: I'm no pro, but I'd prefer to come 25th than 33rd. And not waste my entry fee. And not get soundly beaten by my frenemies. Tubeless for the win (or 25th as the case might be).
  • + 2
 @chillrider199: lmao, "I know a lot of workers from WTB who would say what I said"

You got me bro

Not all pros run tubeless...can't speak for XC because I really couldn't care less about it, but for the sects of this sport that I care about it's still somewhat of a mixed bag.

I run tubeless on my trail bike as I'd rather burp landing sideways or railing a berm than flat and running a tubeless setup has allowed me to ride hard without flats for years and not feel obligated to carry a pack and/or a spare tube + co2.

Maybe I'm in the minority amongst PBers, but I also don't run super low pressures.

Tubeless weight savings is nominal at best...

Bringing up pro XC racers in the context of this conversation is a joke as pro XC racers will save weight literally ANY WAY they can.
  • + 1
 @nvranka: Yeah thats why I brought it up. Pro XC racers ride through some really gnarly shit sometimes. Yet they still run tubless on tires that are thin and light. They put in a tube and things feel different and they also lose speed. Yeah most "Enduro" racers dont give a shit about weight. But if they dont have to repair a flat in the middle of their race run the. They are a happy camper. I myself had a 140mm trail bike with WTB tire and rim combo. Would I ever go back to tubes with those wheels and tires on the market? Nope. You cant burp the tire off unless if you weigh 300lbs. They make a slightly heavier tire that is very difficult to puncture and roll off. Other tire companies do this as well with harder rubber. Tubeless is just suppieror. If youre running a harder tire pressure to not burp then learn how to put your weight into the bike harder.

 My 26+ wheels are rediculously fun until I smack a hit, burp and dent. I've become an expert at using a rock and my wrist guard to smash the damn thing back to almost round and getting it to seal with a mini pump. Big tires and wide rims with low pressure break on rocks. For lighter riders there is a small window between supporting the sidewall and bouncing off the trail.
The price is stupid high for a piece of foam. Maybe that's why the logo has a face covered with a bandana. Pinkbike please check these out.
