Why does my quick release keep coming loose?

The repeating animation to the right shows how the quick release is closed to tighten the wheel in the fork/frame. Notice that it is flipped over on itself 180 degrees. If you do this and the quick release doesn’t feel tight, or if the wheel is still loose, you need to adjust the quick release’s tension.

Which is better quick release or thru axle?

1. Thru axles are safer– This is probably the biggest benefit for the average cyclist. Thru axles improve safety by making it nearly impossible for the front wheel to come out of the dropouts while you’re moving. The dropouts can’t lift off of the axles vertically because they have holes instead of a u-shaped slots.

Where do the springs go on a quick release wheel?

The lever goes on the non-drive side of the bike (i.e. the side without the gears). One spring should be on the non-drive side of the bike and the other spring should be on the drive side. The smaller ends of the springs should be pointing towards each other, towards the center of the skewer.

Are quick release springs necessary?

The springs help you center the skewer in the dropout which makes the wheel easier to install. You don’t need them for the QR skewer to work, but they’re nice to have — if they’re damaged or lost, don’t worry about it. Once the wheel is on the bike, they don’t do anything.
