Tire Test Geax Barro Race 29er Tires

Posted by FatBob on July 26, 2010

Summer is here in full swing. With 100 degree weather comes different riding conditions then our wet cold winters. So I started calling a couple of companies I have been meaning to call for a while to see about getting some tires to test.

If you have been reading 29eronline you may have noticed we are proponents of tubeless technology. We have risked and lost some blood in the process of testing some tires as tubeless even though the tire was not rated as a tubeless tire. So I was really hoping to find tubeless rated tires.

Then came a company I have been eying for a while named Geax. Geax has introduced a UST compatible Tire dubbed TNT(Tube No Tube) Due to the dryer faster conditions Geax sent us some of their Barro race tires.

First I want to introduce the company. Geax is pronounced jee-acks as Ryan DeLong, Geax marketing manager explained. I like to write out the pronunciation as Gee-axe. Geax is a division of Vittoria who is known for the manufacture of road tires. I sold Vittoria tires and have had good results with the quality. I also realize that the technology does not always transfer over between sports so a test was due.

Here are some vitals.29 x 2.0, 680 grams made for speed and to be run tubeless using sealant(Geax makes their own) on UST rims like the ones Mavic Fulcrum and Easton have available.

These do not fit on Stans rims. Seriously, don't try it. You will read Donn O's article and find out why. Geax does make a non TNT casing which should fit fine on Stan's or any other rim.

So next up I will post Donn's write up.
