I just got my 29er FS, and thought I'd throw out my tubeless conversions. I'm no wizard at this game, and have had a hard time making it work on some tire /rim combos.

On the front I put on a 2.4 Racing ralph, with the Stan's 29er strip over the original strip--instant success.

I thought I'd try the WTP Prowler the bike came with on the rear. I didn't have another $22 Stan's strip, so I tried the Gorrilla Tape "ghetto" method. One layer of Gorrilla, a bit wider than 1/2 tape width, over the original strip. It seemed a bit loose, but after cranking the compressor way up it sealed and has held.

By the way, the bike was spec'd with a nice light tube.
