I have a Diamondback 29’er that I ride for fun and back and forth to work. This morning on me return trip home I ran over some road debris and got a flat rear rite as a result. Luckily I was real close to home when it aired all the way down. I am fairly new to mountain bikes and I do not now what if anything is out there that will prevent this from happening again. I do perform regular checks and maintenance on my tires just like my other vehicles. But I would like to take it further. I saw some road bikes the other day that had airless tires on them. Is there such a thing for 29 inch mountain bikes?
