The article says that the cone-shaped spring keeps the skewer centered in the hub.
I recently had to replace the rear wheel axle, and I lost one of the cone-shaped springs. I started riding without it. A few weeks later, upon starting another ride, it was unusually difficult to pedal. It felt like friction inside one of the wheels, but everything looked fine. "Maybe it's just the wind or the slope..." I got back on, and the friction seemed to have ceased. Suddenly, the friction came back with a vengence, and my skewer snapped. Recovering the lever end of the skewer, I realized that the break was very close to the nut. As I started walking my bike, I noticed that the axle was unscrewing (out the end with derailleur, where the skewer-nut was) as the wheel turned, so I carried it instead.
I am replacing the springs and the exposed-cam QR skewer. While on that subject:
- Can I replace it with any cone-shaped spring meant for bicycle skewers?
- If my rear dropout is 135mm, what length skewer do I need? I already measured the skewer (the metal rod) as 5mm diameter.
- I can go with exposed-cam or enclosed-cam, right? http://sheldonbrown.com/skewers.html
