How long should my cycle chain be?
In order to make absolutely sure the chain is long enough, it should be put around the biggest chainring in the front, the biggest sprocket at the rear and then add one more inch, i.e. one link because of the derailleur (one link consists of a pair of outer and inner plates, as shown in the picture below – it is often …
How do you calculate chain link size?
To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.
How do I know if my chain is too long?
Do a simple check on your bike by shifting the chain to the big chainring and the biggest cassette cog; then, push on the end of the derailleur cage (pushing forward) to see how much it will move forward. If it moves just a little, then you’re good. If it moves a lot, then you’ve got too much chain.
How long is a 116 link bike chain?
One link is two pin-to-pin dimensions. Each pin is 1/2″ from its neighbor, so a full link is 1″ long. When they say the chain is 116 links, they are really saying there are 116 pins, for a chain length of 58 inches.
How do I know if my chain is too short?
You should be able to make the shift to the largest cog easily. 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.

Is my MTB chain too long?
Here’s How: Do a simple check on your bike by shifting the chain to the big chainring and the biggest cassette cog; then, push on the end of the derailleur cage (pushing forward) to see how much it will move forward. If it moves just a little, then you’re good. If it moves a lot, then you’ve got too much chain.
What happens if your chain is too short?
the whole story… Two simple tests will determine if the chain is the correct length. First, it must not hang loose in the little ring, little cog combination. If there is no tension on the chain in the little ring, little cog combination; remove two links (one inch) at a time, until there is.
Is 114 link chain long enough?
In most cases it will be long enough. I have used a 114 link chain with 34/50 and 11-40 cassette on 422mm chainstays. setup is 34×50 chain rings.
How do you calculate the length of a chain?
Place the chain over the largest sprocket and the largest chain ring and bring the ends together without routing the chain through the derailleur. Count four more chain links to the length and detach the links you don’t need at that point. Link the two ends of the new chain and voilà: a chain of the correct length is ready.
How many rivets do you need for SRAM derailleur?
A SRAM® derailleur with an eleven or twelve speed cassette and a single front chainring with no rear suspension. With this system, add four rivets from the reference rivet. Another consideration deals with rear suspension. The distance between the rear cogs and front chainrings will change as the suspension compresses and moves for bumps.
How many links do you need for a chain?
When using newer gear wheels with 11 teeth, the chain length needs to be extended by 2 links (2.55 cm).
What kind of chain length do I need for a track bike?
Rigorous Equation. Examples of bikes using the rigorous equation would be a track bike with a large front ring, perhaps a 55 tooth, and a small rear cog, such as a 11 tooth. Additionally, to require the rigorous equation, the bike would need a very short chain stay, such as 15 inches or under in length.
