Tubeless

Has anyone tried going tubeless like described by Ali in this video?

I'm going to give it a shot whenever I get my bike working again.

I bought tubeless everything around the time that came out. It has been sitting on my workbench since...

Only going for tubeless on my hex, don't think the comp bike would work.

Asked Ali on trials forum, he said it works alright especially with spank rims

Tubeless

I plan to give it a go! Currently my trials bikes are the only ones with tubes.

2 main concerns are bleeding sidewalls on thin streety tires, and small casing cuts from hitting rim.
The first problem is solved by tire choice I guess. And the second by proper tire pressure and by Huck Norris (or Procore for better bead retention).
So I see no reason why not.

I've also been debating on converting the Comp bike with the Hashtagg rims. Probably a dumb idea, but they hold a bead so well!

I'm using this... https://www.mcmaster.com/#86205K62

But I think it's a little thin. Something similar can be found at Home Depot, I think! In sheets...

What is the foam for, to protect the rim from impacts? I use the 20" tube stretched on, slit down the middle and folded over the side of the rim trick. I run 45 psi in my tires and I loose a pound or two during a ride. That is on my street bike, I wouldn't consider it on my pure bike. I don't think this setup would stand a chance with only 18 psi and off camber tire folding stuff.

I have tubeless on my Van Dessel WTF...that's it....and that's only cause I was given the tubeless tires and they suck ass with a tube in them. I had tubeless road and they don't seem to like to hold air. Ride nice, but so do cotton and/or graphene tires....better than tubeless....almost like tubulars.

I love the way it rides...but jesus fuck is it a PITA of you like switching tires or you just can't quite get it to hold (like 2-3 days it goes completely flat with no signs of sealant anywhere.)

I use tubeless in the rear tire on my moto trials bike. the pressure drop is annoying, but for moto it's 100 times better then a tube, u can run super low pressure, no pinch flats, waaaaayyyyyy more grip, better bounce. All because u can run lower pressure. But that's moto trials

Tubeless

Foam is for anti-pinch/dent. Procore will prevent burping, but foam won't.

Tubeless gives you less rolling resistance, less weight, and more traction.

With foam, you can run the pressures you want without worrying about your rim or cutting a tire.

With Procore, it's much the same, but it also holds the bead from burping. It may not help as much with side-impacts, especially on wider rims where the inner casing is stretched out. Oh, and it's heavy.

So I broke my wheel down and added the foam just for the heck of it and used Stans Sealant instead of the Slime from Walmart and went for a ride and didn't loose any air. Let it sit over night and still didn't loose any. Not sure if the Stans did the trick or if I just prepped everything better and got a better seal but it's holding good now.

The main problem with tubeless comes when you wear the sidewalls of the tire a bit and it just seeps through constantly. Wastes the sealant and loses air.
