That was for sure the physically hardest task I have performed on the DR. I do not look forward to doing it again. The front tire is reasonably hard but the rear is not. I'm glad to know that I can change tubes or tires, if I have to, with what I carry. Tires, tubes, balance beads, brake pads and knowledge of how to install all of that shit. My arms and fingers are fatigued but I can't wait to ride this new school tire technology. It's the most important upgrade you can make if you think about it.
