During a race in 1927, Tullio Campagnolo, then just another an Italian bicycle racer, flatted and discovered that he couldn't remove the wing nuts on his wheel to fix the flat. The sudden cold had so numbed his hands that he couldn't loosen the nuts. Soon thereafter he invented the quick release skewer.
Signore Campagnolo got the design right the first time. His skewer had an internal cam that gripped well and was protected from dirt. But in the 1980s someone decided to "improve" his design by using an exposed cam. This made the skewers a few grams lighter and more modern looking. But they required a larger cam that offered considerably less holding power when the same amount of force was used on the locking lever. Riders found that they sometimes slipped on bikes with horizontal dropouts or track ends. In addition, the cam was exposed to road grime. Unfortunately, exposed cam skewers have become the norm.
So we decided to make reasonably light, well made, and inexpensive internal cam quick release skewer. Here they are.The acorn nut (the one without the lever) is alloy, but it has a chrome steel face pressed on for better grip and durability. It also has a nylon insert to prevent loosening. The other end also features an alloy housing; the lever and cam, however, are chromed steel, so they won't break when you over-tighten them.
