4 Answers. If you are using a bike with a derailleur the number of cogs on the rear hub will determine the chain size you will need. They are always 3/32″ chains. You can get a 5/6/7-speed, 8-speed, 9-speed, or 10-speed chains.
How do I know what size chain I need for my bike?
It is possible to determine chain length from industrial drive train equations, and then cut the chain before installing it on the bike. 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.
Are 6 7 8 speed chains the same?
5, 6, 7 and 8 speed chains
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.
How do I know my chain size?
Go-kart chain numbers take the first letter from the pitch. And the last 1 or 2 digits from the roller width. For example a 420 chain has a pitch of 4/8-inches and a 520 chain has a pitch of 5/8-inches. To start measuring your chain size you need to start at the sprocket.
What is a 3 32 chain?
3/32″ (0.094″, 2.30 mm) chain is used on derailer equipped bicycles that have more than 3 cogs at the rear. Even somewhat narrower chain, typically . 090″ or 2.29 mm between the inner plates, is used for derailer-equipped bicycles with 9 or more sprockets at the rear.
Can I replace a 7 speed cassette with an 8 speed?
A 7 and 8 speed cassette have the same amount of space between each cog. An 8 speed cassette is slightly wider than a 7 speed cassette because of that added gear. … Simply put – 8, 9, 10 speed cassettes all fit on the same hub. A seven speed cassette will fit on an 8 speed freehub with the use of a spacer.
Is 8 speed bike enough?
8 speed rear cassette is good enough- Providing you get the range correct for your legs. But that is easier to do with 10 speed- I ride 8 speed(24) and 10speed (20) and have to admit that the 10 speed is easier to find the right cog. Even 7 speed is more than enough.
Will 8 speed chain work with 9 speed?
will not work. Spacing on 9 speed shifter is not the same as 6, 7 or 8 cassetts.
What size is 08B chain?
08B Roller Chain dimensions – ISO R606
|Chain No. DIN||P x W||Width W (mm)|
|08B-1||1/2 X 5/16″||7.75|
|08B-2||1/2 X 5/16″||7.75|
|08B-3||1/2 X 5/16″||7.75|
What is the difference between #35 and #40 chain?
The main difference between the 35 and the 40 chain is that one is rollerless and the other has rollers. The two chains also have different pitches and diameters, which will limit their interoperability. Additionally, the 40 chain is rated for a significantly higher tensile strength and working load than the 35.
Will 40 chain fit 420 sprocket?
The pitch will be the same but a 420 motorcycle chain is narrower than an ANSI 40 or 41 chain, so no it won’t fit.
Is my bike chain too short?
If you can’t shift into the big ring/big cog combo, the chain is too short. If it makes it, then it is ok. I have a couple bikes that just make it into the big/big combo and they don’t make any more drivetrain noise than the others.
Do I need a longer chain for a bigger cassette?
You need a bit longer chain for a larger cassette. All things remaining the same, if your chain was the correct length before, adding the 34t gear increases the diameter of the low gear. That increases the total gear length, so you would have to have more chain to keep the adjustment correct.
When should I replace my 12 speed chain?
If you are using an eleven or twelve speed chain, replace your chain once it has reached 0.5 percent wear. For two-sprocket or single speed bikes, replace your chain as it reaches the 1 percent wear mark.
