Can your tubeless do this?

I've been singing the praises of Ghetto Tubeless for a while now. After seeing this video on Stans NoTubes site, I decided to try it on my system. I aired up the tires to 30psi and first tried to roll the tire off the rim. No go, couldn't get it to even close to burping. Then I used a C-clamp and clamped down till the tire side walls were touching, still no burping...AWESOME

Wind, Hills, and Chip Seal

No, this was not a ride in the European Peleton...this was Cowlitz County. Still early in the road riding season, we rode a hilly Pacific Ave to a flat but very windy Willow Grove. Willow Grove is a great place to ride, as there is hardly any traffic. But it sits right on the Columbia River and the raods are mostly chip seal so sometimes even on the flat road, it can feel like your riding up hill. Anyway, it worked out to only be a 28 mile ride but that was plenty for me. My 25c tires and compliant Land Shark frame and fork were more than sufficient for the chip seal. Smooth riding!

Ghetto Tubeless Update

I thought I would give a 3 month update for my Ghetto Tubeless experiment. I have run two sets of 29er tires, both with wire beads and here are some results for each.

Kenda Nevegal 2.2"
-Mounted very easily, able to seat bead up to 60psi (did not go above that)
-Sealed well after a couple of rides, no seepage after sealing
-Ran 28psi with no issues
-Holds pressure once sealed as well or better than a tube

IRC Mythos II 2.1"
-Looser bead fit, a little more difficult to mount
-Bead blew off at 50psi when mounting (made a fantastically loud boom that sent my wife to the garage asking what I was doing).
-Continues to seep small amounts of sealant from sidewalls even after several rides
-Holds air as well as tubes despite seepage issues
-Ran at 30psi with no issues

So far no flats, no burps, no tire rolling...probably due to the 26.5mm wide rims and WTB's fantastic Safety Seal bead lock...I highly recommend these rims for Ghetto Tubeless.
