Broken bike help needed?

Question

my bike is making this cracking noise sometimes when i pedal and when i hear the noise, my chain is skipping. Does anyone know what is wrong or how to fix it?

Answer 1

Cracking noise when you pedal = bottom bracket problems.

Go to your bike shop and they will either adjust it or replace it.

Your chain is prob. skipping because you need to replace your cassette...is it old and worn? If not your derailluer may need to be adjusted.

Good luck.

Answer 2

you need to adjust your rear derailleur by turning the barrel which the cable run thougth it  . turn it 1/4 turn a time counterclockwise , until the chain no longer skip . move onto the next gear and do the same . do this with all your gears . when this is done right there will be no more skipping . good luck .
