[Closed] Huck Norris or equivalents?

It seems like a good idea and I can see that it might be more than just a cut up roll mat but similarly, someone somewhere is having our collective legs up charging that for some repurposed foam.

Procore works with any brand of tyre

Two friends who tried Huck Norris both agreed it was crap, the ones who have tied Procore have all found it pretty good, it does what it promises to do, but can be a bit faffy (valves clogging is one issue)

After suffering multiple punctures last weekend on my hardtail and more or less writing off the rim. I've been eyeing up huck norris setup

What tyre did you have on the back?

Wow £130 for procore...

Why was the huck norris rubbish, inparticular?

@chiefgrooveguru it was a maxxis ardent, tubeless ready tyre (29x2.4) on a pacenti dl31 rim set up tubeless.

That's all i can remember right now. Definitely not a super strong one.

A friend seems to rate huck norris for rear wheel use with exo-type tyre casings.

I'm happy with supergravity casings myself. Less of a commitment in faff if I wanted to change tyres.

I'd just go up a grade of sidewall burliness, so to Exo if it isn't. And if that isn't enough to Super Gravity or Dual Defence etc. I don't know how an Ardent 2.4 stacks up in toughness compared to say a High Roller or Minion 2.4 - often the less knobbly tyres have less tough carcasses too.

The main ride ending puncture was a mega ding in the rim that caused the tyre to unseat from the rim bead. Wondering if huck norrises would have saved my bacon.

After going to increasingly heavy duty tyres to resist pinch flats at low pressures, I've just given in and bought procore for a very good price from 18bikes.

I looked at Huck Norris, but it's expensive and is a consumable, whereas for not much more, the procore is reusable, and rather than adding more weight I can off-set the procore by using a lighter tyre.

I've yet to install it, that's next weeks task when I'm on leave.

What presssure did you have in there? And is your pump gauge accurate?!

Who me? Probably about 20 psi in the rear. Tested it against a digital gauge and they correlate. The rear tyre had been low on my previous ride so maybe it had a slow puncture and could have been lower than 20psi when i set off.

It was a particularly rocky excursion too, compared to my normal riding. In hindsight I should have checked my pressures before I set off, but I dont want somethnig like that to spoil my ride again. I did have a tube, but that punctured (then multiple snake bites getting to the bottom of the singletrack) and then my spare-spare was the wrong valve 🙁

I went Procore as was sick of pinch-flatting tubeless tyres. I only run it in the rear, as never had any issues on the front. I'd rather run a lighter tyre and Procore than be limited in my choice of heavy rear tyres. It has made a huge difference to my riding - I can now run the pressures I want with the tyres I want without fear of burping / pinch puncturing / dinging rims. Expensive but, for me, worth it. I found installation to be dead simple and it certainly won't stop me from changing tyres (actually easier than changing tubeless tyres without a compressor).

Rear only is the plan for me, then I can do both bikes. Good to hear it's working out qtip.

That's really low for a hardtail on rocky trails unless you're a featherweight! I'd be thinking closer to 30psi.

Fitted Huck Norris in my Krampus and had no punctures since.
Rode my Codeine at the weekend, got a puncture (pinch - hole by the rim sealed thankfully, had to fit a slug to the other one) Bought another pair of Huck Norris.

Procore is approx 200g more per tyre, but I dropped carcass weight to compensate, been running it for long enough to wear out a set of tyres.... that's the first time in as long as I can remember that I've not had to write off a tyre before the tread was dead! So it's a win for me...

That being said, if I was getting away with 20 psi and rarely having trouble I wouldn't bother and just put a few psi in, esp for rocky stuff.

I was running about 40 and still smashing rims

Agreed, I'm not heavy and run just under 30psi on both the hardtail and full sus.

Yeah I know that now. Subsequent punctures after upping to 30psi were foreign objects through the carcass rather than pinch/ding instigated.

I weigh about 14stone so the rear was probably a bit low. I normal ride a lot more loamy/mud where low pressure is better from a grip perspective.

Procore working well for me too.
I think it makes a big difference on the front too, not just the rear.
On the front I can go much lower pressure that ever before. Was previously burping tyres when I got below about 20psi.

On the rear, I found out last week that I'd let my sealant run dry and was slowly deflating over the course of a ride. I'm guessing I was down to about 10 psi towards the end of the ride and could easily feel the procore inner by hand.
Partly out of laziness, partly as a test, but mainly because the pub was calling, I decided to ride the final rocky descent on it anyway.
No problems at all, no burping, no rim damage. Can't recommend it highly enough.
Also agree that it makes getting tyres to mount much easier than "normal" tubeless.

There was a really interesting system on NSMB a month or so back that looked to be a good alternative to both procore and hucknorris. Will see if I can dig it out.

Edit here you go Cushcore.

Essentially, it made no difference. Pinch flats without, pinch flats with

What's the one that Gwin was running?

Found it, Flat Tyre Defender... $125 so like mega moneys.

hmmmm maybe I'll go B&Q and buy some pipe lagging.

Weight in lbs / 7 = x
Front tyre in PSI = x -1
Rear tyre in PSI = x +2

Gives a good ballpark for tubeless then modify from there.
Works a treat but remember it's geared up weight.
I've found SuperGravity tyres can take substantially lower PSI than any of the normal SnakeSkin / EXO tyres - all of which work great with the formula.

I've found I can get away with lower PSI on the front tyre but I don't risk it too much on the rear. I tend to lighten the front more than I'm able to with the rear. It's rare that I'd smash a front tyre into something too badly. Most of my tyre problems have been rear ones since I started riding anyway. YMMV.

Is there anywhere that sells Procore in singles rather than pairs?

At £55 for two pieces of foam tied into a loop with a piece of velcro strap the Huck Norris is silly money. At £30 from Rush Cycles I thought 'that's more like it' and bit the bullet... but don't be fooled. Rush Cycles are splitting the pack and selling them in singles and not being very clear about it (feel free to make a trade misdescriptions claim, I have warned them !).

So, I've been using the 2 ply Maxxis Aggressor for a few months after going for an amazing stretch using Specialised and Mavic tyres with very few punctures or split side walls. The Aggressor is a great tyre for grip and wear but crap for puncture and tear resistance.... you don't want to know how many I've gone through, but Maxxis are now investigating !!!

I thought the Huck Norris would be the answer to my problems, so with a brand new Aggressor and a £30 Huck Norris installed I rode out to the Lakes but the first rocky descent flatted with a split along the bead and a hole in the top plus a nice dent in the rim. The Aggressor is now in the last chance saloon with a DD version and the Huck Norris back in place.

One thing to bear in mind if you do flat with a Huck Norris in place and have to put a tube in, you have to take the sticky piece of foam out and carry it back with you... not nice.

For what it's worth I rode in Spain last year with someone with a Procore set up and he punctured twice.

In summary, the Huck Norris might help but the tyre still needs to be up to the task and at £55 or £30 it's not worth it IMO.

WTB tyres. Bombproof.

WTB tyres. Bombproof.

Yeah, but IME with Vigilante's the tread is made of cheese and lasts for about 3 rides and they are a bitch to get on and off certain wheels !

Front tyre in PSI = x -1

The Stans formula works much better translated into English:

Weight in stone x 2 - 1 = front tyre psi
Weight in stone x 2 + 2 = rear tyre psi

Basically, think about it being twice what you weight and that's a good starting point.

Mmm. Not so sure about bombproof I holed the top and the sidewall at the same time on a Breakout on a descent that wasn't even that rocky.
Our guide in Spain last year was also running a Breakout on the rear and

Mincing, I can't be held responsible.... 😆

Don't know about mincing but he was fannying with his tyre instead of guiding.

😆

Anyone know the life (anticpated?) of Procore. The foam insert type look like they have a limited life.
PS - Trusty found 29" Procore at half price [url= https://r2-bike.com/SCHWALBE-Procore-Set-29_1 ]here[/url]

My friend ran a huck norris at the weekend. First hill he got a snack bite puncture. The main hole was repaired but the other knee was on the bead and couldn't be sealed.

We had to put a tube in.

That meant that he had to find somewhere to stash the huck norris that was covered in sealant. In the end he ditched it and picked it up on the way back.

Been running procore for a year now and had to replace a tube due to the valve clogging beyond saving. Tubes are around 20e IIRC.

It paid for itself when I cut a rear tyre on the Ard Rock as my rim would have been battered to hell on the rocks by the time I'd slowed down.

Never thought of that!

and carry it back with you...

Just leave it with the gel wrappers for the fairies to pick up surely?

Me I'd just put the tube under it though tbh if i didn't have an empty carrier bag in my pack

The Stans formula works much better translated into English:

Weight in stone x 2 - 1 = front tyre psi
Weight in stone x 2 + 2 = rear tyre psi

Basically, think about it being twice what you weight and that's a good starting point.

Funnily enough, these are exactly the PSI's I run! I did think reading that people run 20PSI or less quite low. I find that the tyre sidewalls get squirmy in corners and berms for anything less, my rims are 29mm internal rim width too.

there is such variation in pressure readings from pumps that any quoted tyre PSI is, pretty much, complete bollocks.

i`m in the low pressure squirmy tyre camp group also. i need a specialized grid (or equivalent rear tyre) on teh rear of the HT to combat squirm. or a few extra pumps 'squidge squidge' - yeah thats hard enough.

That Stans formula thing is handy as a start up figure.

Thanks for that guys, was going to make a post that subject.

I'm a procore convert. they are expensive but

[*]actually easy to fit, despite the hype (no need for compressed air) although this might depend on rim choice and maybe I got lucky
Run low pressures, crazy grip levels. I'm running +/- 1 bar.
Puncture protection; OK I do pretty well on standard tubeless
Rock solid bead retention. you could run the main chamber completely flat, the bead would still be locked to the rim by the inner chamber (this is actually the reason I first tried them, after a burp/fall/bones broken incident 3 years ago[/*]

Downsides they are pricey (even shopping around you're still spending 100 euro/wheel) and they do add weight, but for me it is weight well spent to get the functionality

so in the end a bit like a dropper post. expensive and heavy but bloody hell it works so well I almost can't imagine being without it

Buy closed cell foam and cut your own.

I generally apply the fruit squeeze test. Orange front, apple rear, banana something's wrong.

EDIT. Quoting appears to be borked?

mr wolfbanger foam inserts make pro core look good value

Was interested in HuckNorris but seems very mixed feedback....

thread resurrection time .... has anyone found any 'other' solutions to the rim ding/split tyres problem yet? i need to do something as im going through rear tyres like chain lube 🙁
