Me running GEAX Barro Race 29" tires at the 24 Hours of Finale last month
So, I’m still very much a skeptic when it comes to tubeless tires. I find all the work involved with fluid, taping, valve stems, etc. just kind of TOO much work. Well, not really kind of. Definitely. To top it off, the thing that really has made me more or less avoid it is the fact that almost all tires that I’ve ever attempted ghetto tubeless with have required a compressor or very expensive (in Europe) compressed air cartridges to inflate the tires the first time. I don’t have a compressor and the compressed air is just too expensive to waste the money for a test run.
GEAX Saguaro 29" TNT Tire - one of my favorite tires
That was until I received and FINALLY got around to trying my GEAX Saguaro 29″ TNT tires with the Geax Pit Stop fluid. Quite frankly, I’m shocked how easy it was to get them pumped up and to hold air.
I’ve had a pair of wheels sitting around here for a year or more that I’ve never been able to get trued. The hubs are White Industries laced to Salsa Delgado 29’er rims. I now know why Salsa has quite making these rims. Unlike the rest of Salsa’s quality line of accessories these rims are soft, too soft. Try as I might I’ve honestly never been able to true either of these wheels. I guess I’m just going to have to chalk it up to experience.
In any case. Mounting the tires, for me, wasn’t any more difficult than your average Continental tire (the hardest to mount, I’ve ever seen). It took me a few tries with two levers to get the one side on. After that, I read the instructions on the Pit Stop fluid which said to put about 50 ml. of fluid in the tire. I opened it up, looked at the weird grey color (very similar to the color of the GEAX sidewalls) and poured in about 50 ml +/- a bit. I then sealed up the bottle and mounted the rest of the tire without a whole lot of difficulty as then the edges of the tire had a bit of fluid on them.
Pit Stop TNT fluid - does 3 tires according to package
Next I hooked the floor pump that I have up to the valve stem (Stans) and started pumping. At first it didn’t seem that it was going to work so I wiggled the tire around till it expanded in the rim a bit and then it started to fill with air. About the time I hit 40 psi it did the fimiliar POP! and I knew that I was almost homefree. I then unhooked the pump, did the tubeless spin/wiggle until I saw no more fluid escaping from anywhere or heard any excaping air. I then hooked up the pump, pumped until I was at 40 psi and removed the pump and screwed down the presta valve.
Geax Saguaro TNT tires and Pit Stop TNT fluid... a great pair
That was a week ago. Believe it or not, it’s still full as when I filled it the first time. All I can say is WOW… I’M IMPRESSED! Geax has a new convert to tubeless if it works that easily on all rims. I need to try it on my WTB Speeddisc rims on my Black Sheep and see what happens.
I’ve been a huge GEAX fan since way back when they started with Ibis (which I’ve now found out they’ve always belonged to Vittoria – thanks Rico). They’ve always been innovative and kind of ‘under the radar’. Things just seem to be getting better and better though. So, when the chance to have them as a team sponsor came up, I grabbed at the chance. Personally, I’m really glad that we did it. Super quality, great tread patterns and this TNT thing is pretty awesome. I’ll try to let you know how it continues to work out as I continue to play with it.
