With
up to 116 links
in a standard bike chain, it has more moving parts than any other bike component.
How many links are in a typical chain?
The chain is a unit of length equal to 66 feet (22 yards). It is subdivided into
100 links
or 4 rods.
What size chain do I need for my bike?
Add the multiplied chainstay length, the divided number of teeth for the chainring and rear sprocket, and add 1 (or 2.5 cm)
. The result is the ideal chain length for your bike. For example, you'd add 32.5, 13, 7 and 1 to get 53.5. The length of the chain should be 53.5 inches or 135.89 cm.
How long is a bicycle chain link?
Twenty half-links in a new chain measure
10 inches (254 mm)
, and replacement is recommended before the old chain measures 101⁄16 inches (256 mm) (0.7% wear). A more conservative limit is when 24 half-links in the old chain measure 121⁄16 inches (306 mm) (0.5% wear).
How do I know what size chain I have?
How do you calculate chain links?
- Calculate C, where C = CD/p.
- Calculate A, where A = Z1 + Z2.
- Calculate S, where S = Z2 – Z1.
- Refer to the adjacent table to find the T value for the calculated S value.
- Chain Length in Pitches, CL = 2C + (A/2) + (T/C)
What is the length of one link in a 20m chain?
| Type Length Length of one link | Metric chain 20 m or 30 m 20 cm | Engineering chain 100 ft 1 ft | Gunter chain 66 ft 0.66 ft | Revenue chain 33 ft 2 1 16 |

How many links does a Shimano 105 chain have?
This new Shimano Ultegra comes with
116 links
, the standard length. Most modern road bikes will require five or six links removing, depending on chainstay length and gearing. Some Shimano 10-speed chains are directional and must be fitted with the Shimano logos on the outward face of the links.
What size chain do I need for a 7 speed bike?
| Drivetrain* External Width, in External Width, mm | 9 speed 1/4′′ – 9/32′′ 6.5 – 7.0mm | 10 speed 1/4′′ – 9/32′′ 6.0 – 7.0mm | 10 speed narrow 7/32′′ 5.88mm | 11 speed 7/32′′ 5.5 – 5.62mm |

How do I know which chain to buy for my bike?
When selecting a chain,
the first consideration is the number of rear sprockets
. The rear cog sets have been made with 5, 6, 7, 8, 9, 10, 11, or 12 sprockets. As the number of cogs on the rear hub increases, the spacing between cogs tends to be reduced.
What is the difference between 1 8 and 3/32 chain?
A 1/8′′ chain is the most common chain found on single speeds, and 3/32′′ chain is the most common chain found on derailleur equipped bikes.
A 1/8′′ chain will fit on parts that are either width. 3/32′′ chains will only fit on parts designed to work with 3/32′′ chains
.
Are bike chains universal?
No. Not all makes and models of bike chains fit on all bikes
. Most modern bike chains are made to the one-half inch pitch, but this dosn't mean all chains fit all bikes. In order to be as effective as possible, a chain must be suited to the type of bicycle being ridden.
Are 7 and 8 speed chains the same?
Shimano, SRAM and Campagnolo all use the same chain with 8 speeds
. Chain for 7 speeds is a bit wider – 7.3 mm, while a 6 speed one is substantially wider – 7.8 mm. That is why the reverse is not the case and a 7 speed chain and especially a 6 speed one will not work as well on an 8 speed system.
Are 11 and 12 speed chains the same?
12-speed chains can operate just fine with 11-speed cassettes
. The main exception are Shimano's new 12-speed HG+ models which are heavily optimized for downshifting and thus come with custom inner plates that don't mix well with non-Shimano 12-speed components.
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 you measure a link on a bike chain?
What are the different chain sizes?
| Size Pitch Maximum Roller Diameter | 40 0.500 in (12.70 mm) 0.312 in (7.92 mm) | 50 0.625 in (15.88 mm) 0.400 in (10.16 mm) | 60 0.750 in (19.05 mm) 0.469 in (11.91 mm) | 80 1.000 in (25.40 mm) 0.625 in (15.88 mm) |

How long is a link in a chain?
In US customary units modern definition, the link is exactly 66⁄100 of a US survey foot, or exactly 7.92 inches or approximately 20.12 cm. The unit is based on Gunter's chain, a metal chain
66 feet long
with 100 links, that was formerly used in land surveying.
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 many links does a 21 speed bike chain have?
Chains are more complicated than you might expect.
With
