Why does my chain slip in low gear?
Gear indexing issues
One of the most common reasons for a skipping chain is simply a drivetrain that needs a simple indexing adjustment. This is so common that even many brand new bikes can exhibit these symptoms. The good news is that this is probably the simplest to diagnose and fix of all potential issues.
Why does my chain slip when I change gear?
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 keep slip when I pedal hard?
The chain could be slipping due to natural weakening of the chain. Over time, the chain will stretch out and a loose chain means more slipping when pedaling hard. The chain could also be slipping if your cogs are word down. The cogs/crank also wear over time and can leave the chain with not much to “grab” on to.
Why does my cycle chain 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.

Inspection Recap
- Verify chain health with the chain ruler.
- Checking the chain compatibility with drivetrain parts.
- Remove extra lube or grease from the chain.
- Check sprockets teeth health.
- Verify rear derailleur & derailleur hanger alignment with cassette cogs.
- Check shifter cable tension.
- Check freehub body shell.
How do I know if my chainring is worn out?
“Rough/noisy running is the best way to tell if a chainring needs replacing,” says Chris Mckenney of SRAM. “Unless a chainring is well beyond its service life it is very difficult to see this visually; chainring teeth slowly take on the shape of a shark’s fin in use.
Why are my gears slipping?
Slipping gears are usually due to normal wear and tear, which causes them to not engage properly and to slip in and out of sync. It is rare, but there might be a malfunctioning set of gears in the transmission, which is usually due to bad original manufacturing.
How do you fix ghost shifting?
You probably need to replace. The rear derailleur cable some have pointed to other causes of ghost shifting. Including worn chain worn cassette kinking of the cable.
How tight should a bike chain be?
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.
How do I know if my derailleur is bent?
When we're trying to shift. Down becomes quite erratic or vice-versa. The key is to look at the rear derailleur we can see it's bent slightly inward.

Why is my single speed chain skipping?
Your chain/freewheel could be worn out. If you recently replaced your chain, the worn out teeth of the freewheel won’t mesh with the new chain and will cause skipping. Simply examining the profile of the freewheel teeth with pictures of a new one will give you a sense of whether this is a possibility.
