Prob fill with mud but this sounds promising - no more flats

I've just wet myself...
It's an old concept initially developed for light military vehicles, like hummers etc.
The one thing they don't mention is weight. Because you can bet they are heavy.
They would also be very expensive, and useless for many people as I imagine you can't easily change the pressure/tension? How are you supposed to adjust the tension on the rods?
And forget about anything resembling aero efficiency. They probably whistle in the wind like flat spokes x10.
That and a good $50 UST tyre will dent a rim before getting a flat.
Sorry, but it sounds convoluted, complicated and expensive for something that isn't a problem.
I'm not convinced either
90% of flats are because the rider has the wrong tyre pressure. Most of the rest is maybe the tyre is toast. A very small percentage would be serious bad luck.
Passing people in a enduro race fixing tyres is kind of tragic. But really bad management on thier behalf.
Mind you a few years ago we managed to get a podium because the guy chasing me had 2 flats.
That kind of makes me think....I owe a beer to bad management. LOL
Yeah but it's carbon and carbon = bling!
What could possibly go wrong?
Ahhh, but you can't actually SEE the carbon, and telling people "ive got carbon in my tyres" is kinda tragic
Gotta agree with the "bad management" sentiment. However I call it "stupidity"
Watched 'Race across the sky' again yesterday. Lance Drugstrong is way out in front and gets a flat. Firstly, he looks like he's got no idea how to fix it, he just pumps it up with CO2. It obviously goes flat slowly and he rides a short distance to the finish. The very minor advantage of MAYBE 2% (0.6km/hr advantage @ 30km/hr) he could have had by running lightweight tubes, tyres and no sealant were more than undone by the time spent faffing on the side of the road and riding a few k's on the rim. And again, just pure luck it happened at the end.
People often say things like "you only won because I crashed/got a flat/any other excuse", like it makes a difference. ALL of that is YOUR fault. As my motorbike instructor told me years back, "everything is your fault". Same applies to MTB doesn't matter if a n00b takes you out. Its your fault.
As said, I've hammered the life out of a pair of UST tyres with no sealant for nearly a year, and have not even burped air out, let alone had a flat.

So true, like folks with fancy carbon frames that are painted - I don't get it. Personally I like to see the weave
Ah, this is funny
We already have carbon in our tyres. What do you think makes them black?
:0
That just blew my mind a little.
If we're going down that path then I always ride with a full carbon suit of armour on. Unfortunately it's just not particularly strong and is very prone to puncturing and tearing when it unexpectedly impacts with rocks from height or at speed
Carbon is an input into bike tyres, and not as a polymer or other chemical compound. I mean carbon, on its own.

Is it just me or do they look super stiff and uncomfortable? Haven't sold me to swap over from tubeless.
Instead of " hey guys gotta stop - got a puncture" it would change to " HEY guys gotta stop and get another pebble out of my tyre"
Cool to say you got carbon tyres though - assume its the carbon mat and not with the resin otherwise the wrong rock in the wrong way sees your tyre crack-n-fail....perhaps they will use the marketing name cannon-dales??
But agree with the others - since moving to tubeless punctures are a NON issue.
And then the market turns completely to tubeless... ïntroducing the new carbon/nano/whatever non burping tyres"... And they dont explode in your face when you are sealing them up... That hasnt happened at all has it GN... : ) ... shhhhhhhh,,,, boom.....ouch...
geting back to the I've got carbon braging rights......The human body has average of 18% carbon.
carbon fibre on the other hand......thats what we all want. LOL
It does say he is looking at adding a sidewall but realistically aero efficiency is pretty much a non issue at the speeds generally met on a XC bike.
As for adjusting pressures.... How often do people do that, I've been riding for *mumble* years only ever adjust my tyre pressures if the tubeless has leaked a bit, as they do especially in summer.
I know some people are anal retentive about it and adjust pressures all the time for different trails but does 5-10 psi there or there make a real world difference or is it all in your head?
yea I adjusted my pressure last weekend at Mt Annan in the JetBlack 24 hr. I normally run 30psi around my local to prevent burping. Since Mt Annan is fairly smooth & flowy I thought I'd go to 27PSI.
Grip was awesome but I eventually just got paranoid & scared of burping the tyre & loose pressure altogether I could really feel the sidewalls working hard. So I upped it to 29 psi. grip was slightly less but peace of mind not getting a flat.
In the mind probably for the most part.
They'd have to consider tires for different weight riders or make a tyre for an average weight rider.
or like a condom....one size fits all.....somehow.
perhaps different size tires would suit different weights?
