Installation of my PowerTank Mini Monster Deflators. Ok, these things are awsome, and worth the work to install them. But the way I did the install made this is a tough job, mainly due too having to dis-mount and mount the tires. After realizing that I was missing my tire irons that I use to pop the tires off the wheel, I paid the cash to diss-mount the tires after poping the bead on the first one. This is a good skill for Trail Repairs. Which is where I learned how to do this. Lost a valve stem in the trails as a noob, and was luckly enough to learn this from some more skilled wheelers. Deflating my tires is much faster now than removing the Valve Stem Core. I can down my tires all the way in 45 sec. 32x12.5 w/50 pounds of presure.
