How do I know what size chain to get?
How do I know what size chain to get?
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.
Are 6 7 8 speed chains the same?
Chains for 6-, 7-, or 8-speed cassettes are generally universally compatible across brands and speeds. That means if a chain says “8-speed Shimano” you can use it in your old 6-speed, too.
What do chain numbers mean?
Chain Dimensions The digits to the left indicate the pitch of the chain in eighths of an inch. For example, a number 40 chain would have a pitch of four-eighths of an inch, or 1/2″, and would be of the standard dimensions in width, roller diameter, etc.
Can I put an 8 speed chain on a 7 speed?
7.1 mm wide 8 speed chain will fit all the other systems (5, 6 and 7 speed ones).
Are 7 8 and 9 speed chains the same?
7, 8, and 9 speed chains have the same inner width, but 9 speed chains have thinner outer plates for a thinner overall chain. So while a 9 speed chain works fine on a 7 or 8 speed drivetrain, it will be a weaker chain that tends to “stretch” faster.
What number chain is a bicycle chain?
Number 1/2 × 1/8 chain is used for simple transmission without speed shifting; it has the same construction as Standard Roller Chain. Number 1/2 × 3/32 chain is used with a derailleur….1.5. 1 Bicycle Chain.

Will a 9 speed chain work on a 7 speed cassette?
A chain one size narrower than standard rarely presents any problem. Thus, you can use a “9-speed” chain with a 7-speed or 8-speed system, or a “10-speed” chain with a 9-speed system.
Can I use a 8 speed chain on a 7 speed bike?
A 7.1 mm wide 8-speed chain will fit all the other systems (5, 6 and 7-speed ones). Shimano, SRAM and Campagnolo all use the same chain with 8 speeds. The chain for 7 speeds is a bit wider – 7.3 mm, while a 6-speed one is substantially wider – 7.8 mm.
Can I use a 7 speed chain on a 9 speed cassette?
A 7 speed shifter or derailleur will not work with an 8 or 9 speed cassette, so you will need to buy new ones.
How do I identify my chain?
How to Tell What Size Chain You Have
- The distance from the center of one pin to the center of the next pin, also known as the “pitch” of the roller chain.
- The diameter and width of the roller.
- Plate thickness, determined by measuring the plates from one flat side to another.
How do I know if my bike is 10 or 11 speed?
Multiply the front gear number by the rear gear number to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike. If you have one front gear and three back gears, you have a 3-speed bike.
Can you put a 7 speed chain on an 8 speed cassette?
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 9 and 10 speed chains the same?
The main difference between a 9 speed chain and a 10 speed chain is that the 10 speed chain is thinner in width, because of the 10 speed cassette, which in turn means the chain is lighter.
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.
How do chain sizes work?
The distance from the center of one pin to the center of the next pin, also known as the “pitch” of the roller chain. The diameter and width of the roller. Plate thickness, determined by measuring the plates from one flat side to another. Plate height is the dimension from the bottom to the top of the plate.

How do I know what size bike chain I Need?

What is the correct length of a bicycle chain?
When you’ve been riding the bike for a considerable amount of time, the chain begins to slack and lose its firm grip. The proper length specification of your bike’s chain should be 12-inch per 12 chain links. However, if yours starts measuring 12 1/16-in per 12 chain links there’s a problem. With such a measurement, you’ll need to get a new chain.
