Chris that looks bad a$$, I just picked up a taller GT Outpost with Tange tubing and a U brake ( no pics yet) and was going through my mountain bike parts bin yesterday trying to decide on how I want to build it up. I have a pair of Forte Slick City ST tires in 26x1.5 I thought about using until seeing your build, I really like the fat tire look so much better. I don't know if that size tire will fit my frame but I do have a few nice MTB wheelsets starting very narrow to the wide boxed Araya's that I can play with. Do you know how wide your wheels were and or how wide the tire is now that you have it mounted.
