Isn't that foam way softer than crush core? It's very easy to pinch it. It might work like shock air volume reducers, the tire pressure ramps up before it gets close to the rim.
Maybe a pool noodle would work better since it's denser foam.
Good catch, here's someone squeezing the cushcore (very scientific) and it seems a good bit stiffer. I also doubt the half round of diy foam has much bead locking effectiveness given its rounded shape.

The backing rods are also available in other diameters from the same vendor, 1", 1.25" and 1.5", or bigger:

The full 1.5" size would be the same cross sectional area and thus weight as half the 2", perhaps that would be more effective, it would be similar to the flat tire defender product, but who knows about the stiffness.
I've done some more reading on this "backer rod" material. It's very light, about 2lb per cubic foot, and it compresses 25% with 5 psi pressure. For a 1.5" section around the whole wheel, it will weigh about 65g - very light. I'd be curious what it's actually doing in the tire when it's inflated, how much does it compress down just from being under pressure.

You can get polyethylene packing foam board that is considerably stiffer and heavier.

Initial impressions of DHF/SS combo are very positive. Just fyi.
Been on an Aggressor for just a couple weeks now. Got my first flat in maybe 4 years? FWIW, this might be an exaggeration, but I honestly can't remember flatting since my last big vacation to Yurp.
Ironically, this was my first tire with Huck Norris. I think the actual variable was that the sealant was spread out over the Huck Norris so much that it wasn't pooling enough to seal the hole. Weirdly, I'd started carrying a 2oz Stan's bottle recently. Dumped it in, CO2 back to pressure, a couple spittles and good to go. Still holding air in the garage.
My limited review of the Aggressor 2.3, without making assumptions about the flat: Compared to a DHRII; noticed some decreased traction on loose/greasy tech climbs. Corners well. Brakes well. The biggest difference by a large margin is that this is the smallest volume tire I've ridden in a while. It feels downright bouncy. Like the opposite of the damping you get from a DH tire. After the flat, I'm afraid to drop the pressure to fine tune the ride on it. I think the 2.5WT version would be superior.
Went from Butcher Grid to EXO DHRII to EXO Aggressor. Perhaps I've discovered the limit that my tire weight should stay above!
Burly as fuck, this guy! :yourock::fm:
I'm leaning pretty heavy towards the Procore system, because it would provide a full bead lock on my existing non-tubeless DH tires and rims. I'm pissed I missed the system on amazon when it was $80, that would have been a no brainer.
Or I could just run the revolutionary YES TUBES SYSTEM that forever overcomes all the disadvantages of tubeless tires.
Vittoria is now in the foam insert game, and they are actually charging more than cushcore at $170/set. This shit is nuts. How does a foam cylinder cost as much as a high-end tire?
Weight is the only way to tell. There seem to be several interpretations of EXO. The Minion SS casing feel much more flimsy than the other Mininos, for instance. It's more like an Ardent Race.
Anybody tried the new Maxxis Ass Guy tire yet?
:D

Well, they came stock. The dual compound on the OEM HR-2 is apparently known for its suckitude in the traction department.
Once I wear these out, Ima go back to the good ole Michy Wild Rock'R2 Adv Reinforced, despite their retarded name. They have been my favorite tire since I put them on my old Reign back in the spring of 2016. I did get a flat *once* when I didn't check/top-up the rear tire and pinched it...
Before those, I *did* have an EXO DHR-2 on the rear. I pinched it BADLY the 1st time I had it out. I promptly moved it to my kid's bike. :D
For a trail bike, I'll take a HR2 over a DHR2. HR2 rolls faster and corners harder. DHR2 brakes better and wears a bit better. HR2 in the rear also doesn't pair as well with a DHF in the front, so I usually go for HR2's front and rear.
That's comparing each tire in a 3C / maxxterra compound though. Don't think I've run them in the dual compound.
Whatever works!
For me, I liked the HR2 initially, then tried some DH2 in similar size and whatnot, on the same trails, and very much prefer the DHR2
Ya'll deal with loose kitty litter type surfaces way more than I do out east, I suspect that makes a big difference.
Yeah, the dirt probably matters quite a bit. I find the HR2's need to be leaned a little further in corners, but lock in harder once you get there. That works great in softer, loamier conditions that we have around here. But yeah, I'm sure there are plenty of dirt types where that's not ideal.
And just so we're on the same page, while the HR2 is maybe my favorite tire ever, the DHR2 is probably still in my top 5.
I didn't think the SS Exo seemed flimsy. Sealed up with a floor pump (DHF too) and is a bit stiffer than Specialized control, but also narrower (maybe more in casing than in tread), but that makes it more squared off on narrow rims. I can actually go slightly lower in pressure.
What's with all the tubless insert shit? Is it really so necessary to run 30mm internal rims and 22psi?
I'm sure I'll be back on a DHRII in the butt soon. I just don't xc enough or care enough about how fast thebike goes uphill or on flat stuff. Rather have traction and durability on the way down when I'm maximizing fun than be fast and efficient on the stuff I don't enjoy.
Aren't you in Ft Fun?
If so... maybe try a Wild Rock'R2?
Traction: check
Durability: check (get the Gum-X for rear tire)
Don't give a fuck about rolling resistance: check
I've heard that it gums up in muddy conditions, but if you're on the FR... you know - who the fuck ever sees mud? :D
This deserves to be x-posted from another forum. It's fucking GOLD. :D
"It's a Shwalbe, just cut off all the knobs, poke 9 holes in it and throw it away, it's the inevitable result of the first 2-3 rides on it anyhow."
After reading further, it really seems like the cheapest, easiest insert is $2 foam pipe insulation from home depot.
Seems like an odd DIY choice compared to backer rod.
Maybe not at Home Depot, but online it's $2/ea: http://www.bestmaterials.com/detail....iABEgJ1DvD_BwE
Or you can buy a lifetime supply for $70: http://www.trusupply.com/Backer-Rod1...CABEgKm_vD_BwE
You're not the 1st one to insinuate that I suck. And, to be fair to you and the others, I do. :D
I don't pedal for hours any more. Very often. And yeah, 2.4s.Quote:
I run those harder ones in the back too FWIW. I can't stand sticky rubber for a rear tire on anything I pedal for hours.
I do use the 2.4s though.
You wanna pay me lots for them? They're barely worn. :fm:
It’s about time axiom or brand x or any of these knock off companies start putting out gold tire liners for 20 bucks or special ed and bontrager
They do kill you on shipping for small quantities, but S&H increases minimally as order size goes up. At least to my zip, YMMV. Buying 20 gets them down to $3/ea including shipping. They're disposable so might as well stock up.
Seriously. I've tried to find justification for the cost but have failed so far. I cannot wrap my brain around how these cost as much as a 3C DHF, especially when they're more or less a disposable wear item. 10x the cost of a pool noodle seems like a reasonable upper limit.
You guys talking DH or trail? IMO, Cush Core and the like are overkill for trail riding. I bought a pair of Huck Norris inserts for arond $55. $25+ a wheel seems pretty cheap if it's going to prevent pinch flats and potentially save me the cost of replacing tires and rims. Also, the included fender came in really handy last Fall.
