Can't hurt to try it on a SurRon.
That's thing. I shared that it has been 2,300 trouble-free tubeless miles for me.

:roll:

If I was like "can I run tubeless for the next 2,300 miles", then it might make sense to say "it might be OK" or it "can't hurt to try".

:lol:
No doubt. It's cool that it's been working. We now have a baseline for 'ghetto' tubeless (no insult intended, I'm just calling the gorilla tape tubeless system that. I run it on my MTB and works great.) Obviously at 12psi its trouble free for the riding you do. For me at least, I want to run lower pressure. It remains to be see how low we can go with this setup. I'll give it a go on my new front wheel once the tire comes in and see if it'll work at my 8-10 psi range. Only way to know is to try.

OK just being that the tire will stay on the rim. At that psi I've not had any issues. As for spinning and not breaking a seal, I'm skeptical, but maybe.
If you really need to run such low pressure, "Tubliss" is probably better for you - supposedly you can run all the way down to 0, though I've never used it.

the Tubeliss system gets great reviews from the guys running it. Only downside for it is that it's pretty expensive, and adds a lot of weight. More weight than a tube.

I reported that it worked for me, then you say “can’t hurt to try". Perhaps you meant that it can’t hurt for you to try. I know it didn’t hurt for me to try.

Look I just came here to share my experience and a tip or two. I did not come here to fight or argue.

Now that I can fill it up without a strap I’ll probably try running at a lower pressure. I think a CO2 cartridge should be enough to inflate it too which, if true, will definitely inspire confidence to experiment.

It'd be pretty slick if a co2 pump would be all you needed to carry for the time the seal popped. That'd make the tubeless setup a no brainer.

I don't mean to argue either. I meant can't hurt for anyone to try. A bottle of Stans is cheap.

It would be good to hear more feedback from users doing it I've ordered 17" supermoto wheels that I'm going to put dirt tires on and see if I can lower a SurRon enough for my kid to ride (sort of a DIY Segway X160.) Might give it a go there.

It's is the stock wheel, not sure what you mean about safety thing.
Ok thanks for the details. the safety thing is the extra ridge they put on some moto wheels to retain the bead on a tubeless setup. obviously not necessary with your setup.

I didnt know that rim pins can be used until i saw some old rims on ebay that had pins to secure the tires from spinning and this at buchanan

Hi guys, I’ve been upgrading my Sur Ron steadily and have hit a road block on suspension.

I bought a 2021 fox 40 and discovered the upper triple clamp has changed (2020 fit ok iirc). Does anyone know of a compatible upper triple clamp that has a negative drop to avoid bottoming out?

I also need a zero stack headset, any recommendations for the strongest one available?

Lastly, I plan on doing rear suspension as well but am woefully ignorant in that area as well. Thinking ohlins but matching with fox 40 would look nice if I could find the needed bushings.

Thanks In advance!

The pictures of the 2021 I can find have a top clamp that droops down at the tubes vs the older flat one I have. You want it to go up? Can you just flip it over?

You want low stack height on top or bottom (or both?) The upgraded taper bearing adds nothing to the bottom as it fits inside the head tube but raises the top about 20mm. The only other options I know about are the old original ones and Cane Creek upgrade. I've been thinking about lower handlebars for the kid and thought about mixing the tapered bottom bearing (where all the big forces are) and using the Cane Creek (or old stock one) on the top. That would give the shortest head tube. Basically a zero stack setup.

Has anyone upgraded a Segway x160 battery? I'm buying one tomorrow. Need to know before I buy.

Seems expensive, unless you were planning to change the controller and battery anyway. The x260 is much better for not much more.

Its about $1900 shipped for a bigger battery and matching charger. What sort of killer deal are you getting on a X160?!?

The killer deal is $2500, I had to drive 6 hours to get it so I just decided to hold off. I want to buy an x160 for at least $1200 but I am not going to pay $2500 tho.

The Sounder looks pretty good for that price.
