The DT Swiss RWS Skewer system takes the quick release in a new direction. Laufradbefestigungssystem, or in English, a Ratchet Wheelmounting System (RWS). It has the springs, adjustable nut, and shaft of a quick release, but in place of a lever attached to a cam, there's a lever attached to a bolt head. Turn the lever clockwise to tighten. When there is sufficient resistance (15Nm), stop turning. Press the red button to position the lever in a place where it won’t get knocked around. You’re done, and the benefits are pretty obvious. It provides up to 50% greater clamping force than with a conventional quick release. The shafts are high-strength AL6/V4 Grade 5 titanium. The lever arms are reinforced carbon fiber. Want it off? Twist the red button counter-clockwise and start turning the lever counter-clockwise. This pair of skewers weighs in at 75g total.
