Is my bike chain too loose?

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

On a derailleurless drivetrain, you should be able to lift the chain about 1/2 inch above its resting position at the middle of the chain above the gears. If the chain is too tight, you might feel and hear binding in the drivetrain as you pedal. If it is too loose, the chain could skip or drop, and you can see it sag.

Why does my bike chain skip when I pedal?

Why Do Bicycle Chains Skip? When your bike chain skips between gears while you’re riding, or shifts twice instead of once when you try to change gears, the most common culprit is a loose cable. Your bike cables naturally stretch over time.

Why does my chain keep getting loose?

A motorcycle chain that keeps getting loose is usually caused by the rear axle or chain tensioning bolts not being tight enough. It can also be cause by a new chain not being worn in enough, worn down sprocket teeth, having too tight of a tension, or having the wrong size of chain installed.

What would a loose drive chain cause?

In extreme cases, a loose chain can jump off the sprocket and become wedged in the rear wheel. This could cause serious loss of control and result in a crash.
