What do the conical springs in quick releases actually do?

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, ...

What is the proper position for quick-release levers?

Something noone has mentioned is that the QR lever is not to be touching the frame or fork when in the closed position. Reasons for this are the clamping force is not as high as it could be the ...

What are these washers that came with my front wheel quick release?

Those washers help prevent your axles from dropping out of the dropouts if your quick releases become loose. In the USA, the CPSC requires some sort of secondary axle retention device -- if you don't ...

Can I replace my road bike's front wheel quick release with any quick release?

Yep. Quick releases are standard and interchangeable. You need to make sure you get one the right length for a front hub. Front hubs for a road bike, hybrid or older MTB will be 100mm wide.

Can QR cause Brinelling in hub bearing?

Brinelling happens when the contact stress exceeds the limit of the material. I don't believe you can achieve that alone with a too tight QR, although it sounds like your bearings are so tight that ...

Need I mount my wheel flush to the top of my fork ends?

The QR interface is designed such that the axle is fully seated in the dropouts before engaging the QR. The QR engagement should be firm, but it is not designed to hold the wheel in the way you ...

Does tightening a QR skewer in different ways affect wheel alignment?

It is possible that when you put in your wheel into the drops you are not seating it all the way before tightening the QR. This can lead to the wheel being slightly off angle that would lead to ...

Where do springs on skewer go?

From Sheldon Brown: 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 ...

Can disc brakes cause front quick-release to loosen?

Most of the time, a bike wheel spins around the axle. When braking, the axle suddenly wants to spin around the point where the brake caliper is grabbing. The traditional orientation for a fork ...

Disc brake fork with QR and vertical dropouts: worrisome?

As long as the skewer is set with sufficient clamping force this QR disc brake setup should work fine and from a practical standpoint there will be very little functional difference between this setup ...

Are freewheels really that prone and susceptible to bent axles?

It almost certainly won't happen with a cassette hub. It can happen on standard axle cassette hubs, but it takes a lot, and there's basically always a dropout alignment problem at work in addition to ...

Should front fork sit directly on the axle thread?

That's how it should sit, yes. There is no significant force applied on the threads themselves, the wheel is held in place by the friction forces between locknuts and dropouts. Here are a couple of ...

Why not have the bearings in the forks themselves with through-axles?

Interesting idea but the front axle (whether is be a 15mm through-axle or a 9mm QR axle) does not rotate, the hub-body and by extension the rest of the wheel rotates about the axel via the bearings. ...

Protecting quick-release seats and wheels from theft

I simply put a ball bearing with some grease into the bolt head. You can take them out with a strong magnet. But it is very difficult to extract them otherwise.
