Review | Huck Norris Tubeless Puncture Protection

by 0

Huck Norris is a new brand of tubeless tyre protection, and to cut straight to what you’re wondering: Yes it works. One day I’d put a nice big hole in a tubeless tyre from a clumsy landing, the next I’d repaired it, put this in, and I didn’t think about flats again until I removed it.

When it dings, you still hear it, it just isn’t followed by the usual FWOOSH and crumpling noises of a flat.

When I met them last year, the people behind Huck Norris immediately said “It’s not camping mat foam!”, almost as if that’s the first thing anyone asks. In development they trialled five different densities of closed cell foam before settling on this particular one. Give some a squeeze and you’ll realise it’s definitely harder than your average roll mat; put it in a tyre and you’ll see it also doesn’t absorb sealant.

The packaging also doubles as a mudguard.

It seems absurdly simple: A foam strip joined at the ends by a loop of velcro, with some holes and cutouts so the tyre sealant can still slosh around. It comes in three sizes for different rim widths, and sits up inside the tyre carcass above the rim, providing plenty of cover for the beads below. When your wheel and tyre bottom out on something hard, the foam acts as a barrier to slow everything down. Each impact makes a little slice through the foam, but the chances of a rock cutting the tyre or denting the rim are massively reduced.

Installation is no more complicated than a usual tubeless setup. Perforations allow sealant to still circulate within the tyre.

Depending on just how ham-footed you are, those little slices do mean you’ll have to replace the Huck Norris eventually. The longer you use it, the more chance there is you’ll get unlucky and bash the same spot twice. Despite abundantly slotting the back strip with an assortment of waterbars, rocks, kerbs, cobbles and landings, this didn’t happen to me in six months though.

After six months in the back of a hardtail, it’s looking pretty intact…

Weight is only 70 – 85 grams per wheel, but unlike heavier systems that lock tyre beads against the rim, Huck Norris won’t stop you rolling a tyre or burping at really low pressures. If you’re prone to that, you might want to look at a more technical solution.

… on closer inspection, it has little slits all over from impacts, and this is why it’s ultimately a consumable product.

Compared to those other puncture protection methods though, Huck Norris is much less hassle if you’re a serial tyre or wheel changer. It goes in and comes out quickly, only adding thirty seconds or so to the process of mounting a tyre. Having it in the tyre carcass also makes tubeless inflation just a little easier, kind of like the old trick of putting a strap on the outside of the tyre to force air back toward the rim and tyre beads.

A few of the slits were big enough to poke a finger through, but there were no dents in any of the rims I ran it with.

The photos in this review showing one of the inserts all beaten up were taken after it’d been on the back wheel of a hardtail for six months. The strip in the front tyre was hardly damaged at all, so I whipped it out and put it out back, where it’s still doing its job ten months after I first got it. It’ll probably need changing soon, but it’s been nearly a year of hassle free riding and tyre changing.

This one strip of Huck Norris took six months of abuse without a single flat.


If you want an afternoon project you might be able to DIY something like this, but if you want something that just works, Huck Norris does. A more expensive, more complicated alternative might be worth looking into if you don’t change tyres much, but Huck Norris is a really serviceable solution, and is ideal protection for compulsive tyre swappers.

    This seems ridiculously expensive for what is effectively a strip of foam!!

    When you break it down like that, yes, it does. However, get it prototyped, sourced, manufactured, packaged, marketed and distributed (oh, and maybe make a bit of money for yourself) and see where you get to. FWIW, it’s worth it for the savings in torn tyres and faff fixing punctures, but then I am a bit hard on tyres!

    think I’ll wait until they can be bought for buttons direct from china…

    As a serial rear tyre tearer I really wanted to love Huck Norris but unlike this tester, I managed to still tear a brand new Maxxis Minion DHR and dink a carbon rim within two minutes of first using it. In the Huck’s defence it was a sharp rock and a high speed impact, a random piece of bedrock sticking through what was otherwise a pretty flowy trail in Finale Ligure. The tyre tear was unfortunately unfixable on the trailside, even with the tubeless poo repairs, too big a tear. This led to another problem, unable to continue tubeless I had to throw in a tube which allows no room for Huck so I had a latex sealant covered bit of foam that I had to carry for the rest of the day. Luckily I got inventive, ate my lunch baguette and stuffed the Huck in the baguette bag, otherwise there would’ve been a hell of a mess in the bag! Judgement still reserved, I’m willing to give the benefit of the doubt until it’s had a load more use. One big advantage of it is that after the initial tyre bursting impact, it does provide some rim protection for the following impacts after you slam the brakes on. Details wise, I’m 11 stone and smooth on the bike so definitely not putting too much weight on the wheel. I do, however ride a hardtail and ride ‘endurooo’ so the bike does take a battering.

    That’s really unfortunate, rockandride. It’s true that nothing is going to give you 100% protection if you hit it hard enough – see also Procore hanging out the back of DH bikes sometimes at competitions.

    In two years I’ve flatted Procore once (slow puncture from snakebiting it after letting the inner chamber go down too much in the first place). Nearly year after I got it, I’m running no Huck Norris in the front tyre on one bike, and what was previously the front strip in the back – still going strong for now.

    Considering how much I used to flat and damage rims on a hardtail, I know I’m basically not going to ride without puncture protection from now on.
