FAQ: Bicycle Chain Skips When Upside Down?

Why is my bicycle chain skipping?

Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Shift down into the smallest ring in the rear cassette again, and press your shifter again to see if the bike shifts properly.

Can you put a bike chain on upside down?

If you have such a chain, you ‘ll need to make sure that the inside is inside. You can still reverse its direction though, unless it is also directional, i.e there is a left and a right (the second exception).

Why does my chain come off when I pedal backwards?

If it has a derailleur your gears need adjusting. We properly adjusted shifting system will allow you to pedal backwards without the chain coming off. Something could be bent, like the derailleur hanger or the derailleur itself. If it’s a singlespeed, this means the chain is out of alignment with the two sprockets.

Why does my bike chain slip when I pedal hard single speed?

Anyway, when you’re pedaling hard, there is tension in the top section of the chain, between the ring teeth and the cog. Under this tension, they stay engaged even if the returning-to-ring section of the chain is sagging.

How do I know if my bike chain is too loose?

Check your chain out. It should be tight enough that it only allows you to move it up and down about one inch. If it is sagging or much looser than that, you need to tighten that chain up. Chains often loosen when a bike does not have a derailleur.

What kind of lube should I use on my bike chain?

Use a light, waterproof lube such as Boeshield T-9 Waterproof Lubricant. For wet-weather conditions, try Pedro’s Chainj. Never Use: Motor oil—it contains acids and particles of metal that can compromise a chain’s strength and cause it to wear more quickly.

Does a Shimano chain have a direction?

Each of the four plates, inner and outer, are shaped differently to act in a certain way relative to their position with the front chain rings or rear cogs as you shift up or down through the gear range. This means that the HG-X chain is directional. The Shimano CN-HG900 Chain is directional and 11-speed specific.

Is it bad to pedal backwards?

Can we reverse pedal in gear cycle?

You might want to rotate the pedals backward while the bike is stopped to oil the chain or check that the drivetrain moves freely. The only harm is if you’re between derailleur gears. Then, pedaling backwards can distend or derail the chain, or grind against the derailleur.

Why does my chain keep coming off?

It might be that the chain is worn, has a stiff or bent link, or has become clogged up with dirt. A visual inspection while turning the cranks should reveal if there’s a problem here. The chainring, or a chainring tooth, could be bent. Again, a visual check will tell you what you need to know.

Why is my crank slipping?

As the chainring teeth wear out, and you apply a certain level of torque on the cranks, it becomes possible to exceed the tension applied by the derailleur and the chain will simply ‘roll’ up and over the teeth on the chainring, effectively skipping a tooth. This usually happens very suddenly.

How often should I change my bike chain?

The 2,000-Mile Rule. To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same. 4
