Bare with me if you surf other sites, I am posting this everywhere because I think it is very useful info:

I finally got around to making my rear rim tubeless. I will do the front one next, but I am waiting until the next time I need to change the front tire.

Here's what you need: A tubeless type valve stem, a large cylinder of clear silicone (get at any hardware store), a calk gun to apply the silicone with, and duct tape. That's it.

Clean the inside of the rim off very well, and let it dry. Then apply a big blob of the silicone over each spoke nipple. Let the silicone sit for a few minutes and form a "skin", but not totally dry. Then, take the duct tape (this part is much easier with two people - one to hold and secure the tape, the other to turn the rim) and tightly wrap it around the siliconed spokes. Do about 3 or 4 full wraps with the duct tape, and let it sit and cure overnight. Oh, you'll obviously have to cut a whole in the duct tape at the base of the new valve stem. Also, but some silicone around the base of the valve stem. I suggest filling the tire with air right after applying the duct tape, I think the extra pressure helps push the silicone into all the right places.

It sounds cheap and I was skeptical at first myself, but I figured what do you have to lose? My first test was filling the tire with 60 psi of pressure and letting it sit. No leaks. My next was a quick run around the neighborhood. No leaks. I've done 450 miles on the bike since Friday, and it hasn't lost a tenth of a PSI of pressure.

Good luck!

Re: Tubeless for under $10.00!!! (backdrifter)

Now go and adjust a spoke nipple and let us know what happens.

Adjust your spokes before hand. When you have to do it again in the future, take the tire off and pull up the silicone, then re-apply. It's not rocket science!

Still at 60 pounds? Please tell me you lowered the pressure before you went out riding.
