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.
How do you size a bicycle chain?
To measure the chain, wrap it around the chainring and the largest cog, but bypass the rear derailleur. Make sure the chain is engaged fully on the teeth of the largest cog. Pull the chain tight. Engage the closest pin to where the two ends could be joined on the chainring.
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. … Going further narrower, like a 10, or 11 speed chain on an 8 speed cassette can and often does work.
What chain should I get for my mountain bike?
Chains from most manufacturers should fit, as long as the chain is made from good quality material and matches the number of sprockets in your bike’s rear cassette. Some mountain bikes have 9, 10, 11, and sometimes even 12 sprockets in their rear cassette, and length of chain for each of these bikes will be different.
How do I know my chain size?
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.
- Plate height is the dimension from the bottom to the top of the plate.
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.
What size bike chain do I need single speed?
1/8″ chains are used exclusively for single speed setups. In addition to the other answers, I found it helpful to read that the nominal width of a chain (1/8 or 3/32) actually refers to the width of the sprocket.
How often should I change my bike chain?
To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same.
Are KMC chains better than Shimano?
Summary. The difference between the Shimano chain and the KMC is marginal; your choice will always come to personal preference. … Despite the inconvenience of adjusting the chain, the Shimano runs a lot smoother and will provide you with long-lasting use.
Will a 9 speed chain fit 8 speed?
9 speed chain on an 8 speed cassette is just fine; it’s the wider 8 speed which won’t fit the sprocket spacing on a 9 speed cassette.
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.
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.
How long do bike chains last?
A chain can last anywhere from about 500 miles to 5000, depending on the quality of the chain, the sprockets, how the bike is ridden, and the maintenance.
How do I tell what grade my chain is?
Just look for the “L” and then the number after it. Each number following the “L” corresponds with a grade of chain. On grade 70 this can also show that the chains are DOT approved! The “L” represents Laclede and our commitment to high quality chain products.
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.
