What causes a bike spoke to break?

What causes broken spokes?

The most common reason spokes start breaking periodically one by one on a rear wheel of a bike is due to metal fatigue.

How often do bike spokes break?

You may break a spoke with these wheels every 5 or 6000 miles, but that’s not because the spokes wear out. And that seems fairly frequent to breaking spokes on average, especially for a rider of your weight. There would have to be something going on with the spoke or wheel to cause it to break.

How do you stop spokes from breaking?

The best way to avoid spoke fatigue is to go to a skilled builder, who will advise on spoke count and rim weight (heavier rims are stronger…) and use correct spoke tension and proven stress-relieving techniques to minimise the cyclic loading responsible for fatigue failure.

How much does it cost to replace a spoke?

Spokes are usually $1.00 – $2.00 each. Any shop will sell individual spokes. Labor to replace a spoke is $10 – $20 depending on your location.

Where do spokes normally break?

Most decent spokes break, when they break, at the bend where they go into the hub. A less obvious bend, only now and then but often enough to mention, is where it exits the spoke nipple. Sometimes the nipple doesn’t seat well, and you get a bend there.

Why are spokes breaking at J bend?

All “J bend” spokes will break, given enough time. Low tension, uneven tension, and low spoke count speeds things up. Usually a rear wheel will start breaking spokes sooner.
