Is there a way to tighten a bike chain?
Step 2: Locate the derailleur screw On multi-gear bikes, at the back of the derailleur, there is a screw. On most bikes, you’ll find the letter B, and next to it will be the screw. To increase the tension on the bike chain you’ll need to turn this screw clockwise in a tightening motion.
What happens if your bike chain is too loose?
The problem with a bike chain that is too long or is loose will cause the chain to slip off. And this will affect changing the gears cause the dérailleur does not have enough capacity to pick up the slack with the chain being too long.

Why does my bike chain slip when I pedal hard?
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.
How tight should a bike chain be single speed?
Chain Tension There should be approximately one half inch of movement in the chain up and down at a point half way between the front and rear sprockets. To change the tension loosen one of the axle-nuts and move the wheel forward or backward slightly and snug it up again.
How do I know my bike chain size?
Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs. Next, measure the distance between the middle of the crank bolt to the rear axle. This is also the chain stay length.
