Hi. I got a problem. I just bought new tires for my MTB that are 26x1.3, but the narrowest tubes I can find says it will fit 26x1.5 to 26x2.0. What to do? Anyone know a place that has some really skinny MTB tubes? Or should I just get these ones? Am I risking a pinch flat running a bigger tube than the MTB tire?
