Often asked: How To Adjust Chain Length On Bicycle?

Can you shorten chain length?

Simply clip the chain to your desired length (I usually hold mine around my neck while looking in the mirror so I can see exactly how much I need to cut off, I mark the spot with my fingers & then clip the chain) & then insert a jump ring into the last link.

What happens if bicycle chain too long?

A chain that’s too long (loose) may cause dropped chains and/or inconsistent shifting — front and back shifting. A chain that’s too short (tight) can cause even bigger problems. BUT, things can go really bad … if it does shift and rips the derailleur off, damages the chain or bends gear teeth.

How do I know if my chain is too short?

You should also see two slight bends at each jockey wheel of the rear derailleur. If the chain is too short, this shift is difficult to make and the derailleur cage is stretched out and almost parallel to the chainstay. If the chain is really short, then you might not even be able to shift into the largest cog.

What size is standard bicycle chain?

Chains come in 3⁄32 in (2.4 mm), 1⁄8 in (3.2 mm), 5⁄32 in (4.0 mm), or 3⁄16 in (4.8 mm) roller widths, the internal width between the inner plates. 1⁄8 in (3.2 mm) chains are typically used on bikes with a single rear sprocket: those with coaster brakes, hub gears, fixed gears such as track bicycles, or BMX bikes.

How can I tell if my bike chain is stretched?

Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.

How do you shorten a chain without a tool?

In order to shorten the link without a chain tool, you need an alternative tool like a hammer, pliers or thin nail. They will assist you in pushing the pin easily. You can position the chain over a socket, and hit it with a hammer. Then, you can now pass the bolt all throughout the open holes.

How do I set the size of a chain link?

Chain Link Sizes: How to Measure Chain Link Sizes

  1. Pitch is measured by finding the distance from the center of one pin to the center of the next pin in line.
  2. Determine your side plate height and thickness by measuring both inside and outside the roller chain to ensure that you’re seeing a good average size.

Should I shorten my bike chain?

You either deliberately run the chain long enough to handle your mistakes in shifting (for big/big) or you don’t. You should have better shifting theoretically with a shorter chain, but if you shift big/big by accident you do have a problem.

Why is my bicycle chain loose?

Your chain might simply be too old or can stretch over time. When this occurs you need to replace it. Consider that your loose chain also may be due to operator error. Exceeding the recommended gear range for the rear derailleur on your bike may lead to a droopy chain when you ride in these gears.

What do you do if you cut your bike chain too short?

Registered. To make the chain the correct length, cut one link off the left-over piece of chain that you’ve cut off, buy a second (preferably rivet type) master link, fit them both to the “short” cut chain, and then fit that to the bike using the master link that came with the chain.

How do you calculate chain length?

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.
