Thursday night I converted the front wheel of my 29er single speed to run tubeless. Not having any official supplies (
Stans rimstrip,
yellow tape, etc.) I decided to use what I had on hand.
Using an old, punctured road tube I cut out the threaded presta valve stem. I then removed the existing tube & tire from the rim, covered the existing rim tape with 3 layers of black electricians tape, inserted the presta stem, threaded on the bolt to hold it in place (I used pliers to get it good and tight) and remounted the tire (a 2.4 Continental Mountain King).
At this point I tried to inflate the tire using my floor pump and, when that failed, a C02 cartridge, with no luck. Luckily I have a neighbor who owns a nice air compressor. I drove over and we were able to easily inflate the tire. Unfortunately both the valve stem and tire sidewalls were leaking air so quickly that it was flat in a matter of minutes. However, I hadn't expected the tire to hold air at this point, but wanted to verify that the bead would seat and it would inflate without blowing off the rim.
With that test done I removed a section of bead, poured a bunch of
Stans into the tire (I didn't measure as my bottle was almost empty so just dumped in what was left), reseated the bead and hit it again with the air compressor. As before I began losing air from around the valve stem and out the sidewalls but after shaking the wheel horizontally all the way around (rotating a few degrees each time) the hissing had stopped. I took it home and performed a few more sessions of shaking, laying the wheel on top of a bucket after I finished each, and it's held air ever since. The true test will come when I can get out for a ride (maybe next week I'll do a night ride on the neighborhood canal roads) but so far it's looking good.
