There are three ways to tell if the quick-release lever is doing its job to securely hold your wheel in place on your bike.
1) Most levers have the words "Open" and "Closed" stamped right on them, so look for that. The quick release in the photo reads "Open," meaning that the wheel is not properly fastened and it may come off–even if the wheel and lever feel tight!
2) Levers are usually curved. When the bend of the lever's curve protrudes outward like a bump, the lever is closed. When the bend is cupped (photo), the lever is open. Closing and opening the lever requires flipping it 180 degrees, not spinning it.
3) If a quick-release lever sticks out from the frame (isn't flush with it), that also means it is not fully closed. It may seem to be holding the wheel(s), however, a protruding lever is not locked shut and it's possible for it to come loose or get knocked loose if you bump it into something. Be sure to close the quick release fully if you see this to ensure your safety.
Please note, that even if the lever reads "Closed" and looks right, it's a good idea to test how tight it is by trying to open it by pulling on it with a little effort. If it resists, it's tight and safe. If it opens with only a little effort like this, it's not tight enough. Follow our directions to tighten it. Contact Full Circle Cycle if you have questions.
