Edge Regulators Print Email By Mike Hughes Check out the Edge regulator series by the folks that brought you the HOG. The Edge EXP is lightweight, and easy on your wallet too. The Epic has a brass barrel and swivels. The Edge Ti Extreme is the super titanium model and can be upgraded with a cold-water kit. See Chris explain the model benefits, the new valves for side mounted tanks, and a sneak peek into items soon to be launch this next year.
