900-1000g 36" tire, anyone interested?

[unigoat]

Matt,

The more supportive sidewalls are a good idea. Thanks for thinking things through on the balance of the tire.

Even with "just" the 1 lb weight savings, I'll sign up for a second for sure. The tread pattern is the clincher. Side knobs are a VERY welcome feature in a 36er tire. And a mud worthy tread pattern?!

Bravo.

Just found this thread and would like to put my name down for at least one..

Yeah, I'd love to have one at or before UNICON if it is possible (if they're shipping from Canada maybe someone kind could bring me one to UNICON if it is a matter of days beforehand)! Looking good.

Don't get too frisky, this thing could be a ways off from production, assuming it all works out.

They still have to finalize the design and materials, then the tires have to be molded, money (investors) may not be on board yet, it's an expensive and risky undertaking, I wouldn't put up the backing, though I will buy a tire or two

I'm hopefull it'll work out, my 36er woudl be so much better with a lighter tire.

And one really important thing: This tire is not being produced by Maxxis or Schwalbe, it's a local effort by riders, so if you say you're gonna buy a tire, stick by your word and buy one. If everyone who owns a 36er buys on, then someone might take notice and we'll get even more choices

Yup, I agree it is likely to be a while, and I'd rather it took longer and ended up better than just got here quickly. It was just this that piqued my interest:

So maybe we can hope...

Late July right?

It's looking less likely, but still possible. I'll keep you guys in the loop as we get our hands on the next prototype which should be pretty soon. It dropped some weight but not as much as we'd like, down to 1600g (unofficial). Manufacturer doesn't want to risk liability by dropping as much rubber as we'd like but to be honest they're a pretty good tire as is.

Tread has not changed from the pictures higher up in the thread as it's pretty awesome for an all-rounder.

Too heavy !!!!

+1

[bouin-bouin]

would like to know how light and expensive can be with kevlar fiber

[jogi]

would save some weight...


29" tires are arround 800g, if the weight is linear it should be arround 1000 for 36"....

for sure but I'm interested to know how much weight saving and what would be the price

[jogi]

yes. we have some tires, not to bad,
so it would be fantastic to get a realy high end tire here...

even the now available tires are expensiv so of cause a high end will be more....

Man you guys are hard to please 1600g (have not weighted them yet so could be lower/higher) drops 1-1.5 lbs per tire, depending on what tire you start with. Your Nimbus above is the lightest I have seen one weighed. Mine, even after cutting the tread was close to 2050g.

As for the questions -

Kevlar is a no go due to expenses. I wouldn't buy one and I'm trying to finance this project. New machinery would need to be bought by the manufacturer to make a kevlar bead that big and then you'd need to worry about the amount of stretch you'd get over a circumference that large. Cost aside, that could take a year to get right. And the weight savings just is not worth it - somewhere in the 50-75g range. I also thought it would be more.

Weight is NOT linear in tire construction as you get to the extremes. But I'm no engineer/physicist so couldn't explain it. Just what I've been told and what you when you look at Fat bike tires and certainly the current 36ers, event he "high end" ones

Not sure what you consider a high end tire, but this one will not be much more expensive than the current offerings which is a considerable acheivement given the LOW volume (compare to fat bike tires again at $140+ for the lightest, nicest). We are hoping to cover the transaction costs and a part of my labor when I get to boxing and shipping 200+ tires. Essentially we just want to provide a product that nobody else has wanted to tackle, and not lose any money while doing it.

Thanks for continued updates, Matt. My Nightrider weighs 2098g so even at 1600g that's a full lb off the tire (20+% reduction).

That has been my experience. Going from 2100 to 1800 was a significant difference for me.

I'll also say that there is a member of this forum testing one of our first protos (only has one ride so far). Once he has formed an opinion I'm sure he'll post up with his thoughts so it's not just us bikers giving feedback as the differences in needs may be significant. From his opinion of proto #1 I'm sure we can deduct what another 200+g loss in weight would feel like for this crowd.
