Powertank Monster Valves

If you're running 35-inch or larger tires, you know that airing up and airing down at the trailhead can take forever. Well, maybe not forever, but it can seriously take a half hour. When you're anxious to get onto the trail or back on the highway, waiting a half hour adjusting your air pressure can seem like an eternity.

Powertank's Monster Valves and Mini-Monster deflators are trailhead timesavers.

What's the difference? Monster Valves allow super-fast airing up and airing down. Mini-Monster Deflators are for airing down only.

Installation involves drilling and tapping a 1/4-inch pipe thread in your wheels. This can be done with the tire still mounted.
