This type of seatpost is much easier to adjust than the classic Campagnolo two-bolt seatpost, but can be adjusted only in (small) steps.

Starting with the "bike boom" of the early 1970s, multi-speed, derailer-equipped bicycles were increasingly sold to unsophisticated customers. People would use the quick-release like a wingnut, or would close it without clamping it tight, or would overtighten the adjusting nut so the lever would not push down all the way. A vandal also might intentionally loosen a quick release. A skewer can break if it was bent, or if it is overtightened with gorilla force, or defectively manufactured. A bent dropout might not secure the wheel. Disengagement of the front wheel resulted in nasty crashes, and lawsuits, and led to the introduction of secondary retention devices.

Who invented the quick release skewer?

What is a quick release wheel?

Quick-release wheels use a cam mechanism to allow a bicycle's wheels to be removed quickly, and without any tools. Quick releases are also sometimes used for seatposts and stems. Legend has it that in 1927, Tullio Campagnolo was unable to reverse the rear wheel of his bicycle to change gears while racing over the Croce d'Aune pass in the Italian Alps. His frozen fingers were unable to loosen the wingnuts used to hold his wheels in place. This incident supposedly led to his invention of the quick release, first marketed in the early 1930s, though recent research by bicycling historian David Herlihy has revealed that Campagnolo was not on the list of competitors in the legendary race!

How to remove a bicycle wheel?

To remove a wheel, pull the lever out and away from the wheel and follow through until the lever is fully in the open position. Once the clamping force is released, the lever will easily rotate the rest of the way around to the open position.

Then hold the wheel with one hand and lift the bicycle off with the other .

Can a plastic washer rotate 90 degrees?

There have been reports of a particularly nasty failure mode with the exposed-cam type skewer, related to the radiused plastic washer. If the user isn't careful, sometimes this washer can get rotated 90 degrees, so that the cam presses on the flats as shown in the photo below, rather than sitting in the valley of the curved side of the washer. This creates a likelihood that the skewer can rotate if it becomes loose, so that the cam falls into the valley. When this happens, the quick-release becomes so loose that the wheel can fall out, even if a front fork has "lawyer lips".
