What causes bike chain to slip?
Most of the time, the slipping of a new bike chain is caused by loose cables. The new shifting cables stretch a lot during the first few rides. The cables stretch way too far with time, and that’s when the problem arises, and your chain starts to slip between gears.
Why does my bike chain slip when I pedal hard?
These include worn out or misaligned derailleur pulleys, old or malfunctioning shifters throwing off the indexing in some gears, or broken/bent teeth on one or more cassette cogs. Build up of dirt and grime on drivetrain components will also cause shifting issues, including skipping chains.
Why does my chain fall off when I pedal?
Check the crankset and bottom bracket
If the crankset is loose, it can move sideways during pedaling, which can allow the chain to come off. So make sure the crankarms are securely attached and that there’s no side-to-side play in the crankarm or bottom bracket. Some bottom brackets can be tightened.
Why is my bike chain jumping?
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. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.

Why does my chain slip when I pedal backwards?
