Tony R. wrote a review of Geax Saguaro Tire - 29in on January 20, 2012
Heard awesome things about Saguaros from many people that ride them locally (N. Texas) but I failed to pay attention at the warnings about mounting on Stans Rims. It's not impossible, but quite difficult to accomplish. I was unsuccessful on Arch 29ers.
IMO it is not practical to run tires that are this difficult to mount especially if you have to repair the tire on the trail. As a result, I decided to return the tires and exchange them for a different set.
I may give the non-TNT version a try.
I must say that Huck N Roll has been awesome tho. Wicked Fast Shipping and Excellent Service.
