I live in n.texas where we mostly have hard pack clay with loose moondust over it. These tires are fast and grip well. I run them with stans on both on the front and rear. I race with them too. If you like the specialized fast track, or maxxis icon, then you would like these. The ONLY complaint on these tires is that they are heavier than lets say the icon or racing ralph. If you are a weight weenie then you might want to look at something else.
I rolled on the 2.2 front and 2.0 rear. I ran them both on my 3" travel full squish and also on my SS hard tail. Awesome.
Also, most important is that the regular version will seal up first take with Stans. I ran both the regular and TNT versions on crest rims with stans. Very easy to seal up.
my current setup is a RR on front and one of these geax on the rear. Awesome rear tire.
- cheaper than most of the 29" tires
- fast rolling
- very puncture resistant.
- tough side walls even without the tnt versions
- corner well
- seal up with stans very easy
If they made a lighter version I would still run them on my front tire which is now a racing ralph.
