I was on long trail ride in the North Cascades last night and I pinch flatted about five miles from the trailhead. The sun was going down and I had to change the tube quickly, no problem right? Wrong, I have this small crank bros. piece of sh!t that took about 15 minutes to fill the tire to 25lbs. I need a good tire pump that works well and that is not too heavy. Any ideas? Thanks...
