Sorry I was trying to find a rim company here in the Bay Area and stumbled upon a few forums and sites stating they went tubeless and its been great, etc.

Just curious if anyones ever tried it? They say you can even use house hold silcone to seal the nipples and wrap the rim and your good?

Also since Im on the topic....anyone know of any good places to pick up rim barrel's and spokes? Preferably buying local would be cool but ok with buying online...may even be cheaper.

Thanks!

Going tubeless would increase the speed rating of a tire and you could repair a flat with a tire plug, but what other benefits might you gain? I don't think I'd have any peace of mind at freeway speeds running tubeless on rims not designed to hold them, especially using tips and tricks culled from the internet.

Where in the Bay are you?

Less unsprung mass, less rotating mass, hell, less mass.
With that said, I'm not sure I'd feel safe doing that myself.

If you look on that link theres a guy using home silcone that was suggested by Kenny Buchannan supposingly they do it that way too.

I live in Brentwood Nor Cal not So Cal. I work in Oakland. Just saw you were in Oakland.

What route did you go? How did you end up doing it?

Burnboy · « **Reply #6 on:** June 30, 2009, 12:33:51 PM »

had them laced and trued. then I got a tube of GE brand aluminum latex caulk. Go it at lowes for 6 bucks. Then I just put a glob on each spoke head, let it drive over nit. Did one more thicker coat , let it dry over night. And that was it. I put 40 psi in them and let them sit for a few weeks while I finished my build and they havent lost a pound.

The rim bead lock design is quite different between tube and tubeless designs. It's NOT just a matter of sealing the air in while it's sitting in your driveway or straight up ride situations. The rim design was changed on subsequent motorcycle models to adapt to the newer tubeless designed tires and provide good seal under extreme conditions. If you have the rims for tubeless tires, by all means use tubeless tires. However, if you have tubeless tires mounted on tube rim without a tube in it, the risk is that under some circumstances, like road hazard, or emergency type maneuvers, the bead will pull away from the rim and you will have a rapid loss of air pressure, and resultant very bad handling... just as you slide into the oncoming car lane.

Jump out of an airplane at 20000 feet, and at 10000 feet you can say there are no problems so far...
Maybe in the last 500 feet you will sprout wings, the earths gravity will suddenly stop, or aliens will take a sudden interest in you for further study, and prevent your collision with the earth surface. You just might be "lucky".

You didn’t wrap it or anything? Just put two steps of adding that silicone and mounted the wheel? When you need to true the rims and tighten the spokes won’t that loosen the seal that you put on? How long has it been now of riding, etc.?

Long time ago when I saw it but it seems the main issue with going tubeless is not the outside edge but actually inside. On tubeless rims, there is a ridge inside the holds the tire to the outer edge. When you air up a tubeless and hear the loud popping, it is the tire going over that. Now this a side by side picture and I think it was on advrider site.
I think the easiest thing to do would be to get some bmw spoked wheels since many of those are tubeless and mount them on our bikes.

I found this though, might be something to check out if a person wants.

It overcomes the basic issue of beads.

It appears that it is mainly for off road but the company might do road tires or these might be able to be used anyways.

Interesting....thanks for the link. That seems pretty promising and maybe worth while. Pricing is a little steep.

It kinda is but yet the appeal of no tube and the ability to possibly run flat a ways, well that would be real nice.

I just emailed them and its not DOT approved so in the mean time its only for Off-Road purposes!

Or the race track....

There was a big thread here about this 6 months ago maybe...

Well I dont know about you guys but my state does not inspect the insides of tires

Frankenkit · « **Reply #17 on:** June 30, 2009, 07:54:10 PM »

If the wheels were compatible, why not just go with late model 650 comstars? They're rated for tubeless tires.

But even if you were to get it...I dont think it will work with our bigger tires. But what do I know! $:-\$

I really like the spoke wheels thats why.

Achmed · « **Reply #20 on:** June 30, 2009, 08:29:01 PM »

So with the tubliss system you eliminate the tube but replace it with another tube? How much weight are they really saving?

Frankenkit · « **Reply #21 on:** June 30, 2009, 09:18:22 PM »

kinda rare even now to get tubeless spokes, isn't it?

Accolay · « **Reply #22 on:** June 30, 2009, 09:29:55 PM »

Not that I'm thinking about going tubeless...

...but with the silicone method, what if you had to tighten a loose spoke or true up your spoked wheel? Wouldn't that mess up that silicone in there? (reread posts, seems J-5 already got that bit in his post)

Are tubeless tires really cheap or something? What's the big advantage?

Burnboy · « **Reply #23 on:** June 30, 2009, 11:54:52 PM »

Supposedly the silicone will keep the threads in place. If not you simply dig out the silicone, adjust the spoke and re seal it.

bryanj · « **Reply #24 on:** July 01, 2009, 06:02:01 AM »

Sorry I'm old fashioned with a kneck in one piece and want to keep it that way

no way no how
