Readers ask: What Size Bicycle Chain Do I Need For A 9″ Wheel?

How do I know my bike chain size?

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.

What size is a 9 speed chain?

9 speeds. Chain width is about 6.7 mm. In a pinch, a 10 speed chain can be used. Still, narrower chain is more expensive, doesn’t last as long and will cause a bit slower shifting… but it will work.

How do I know my chain 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.

Are 9 and 10 speed chains the same?

The internal/roller width of 9 and 10- speed chains is the same – 2.18mm. The only difference is the spacing of the chainrings. 9 and 10-speed chainrings aren’t spaced the same way, but the differences aren’t humongous.

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 is the difference between 10 and 11 speed chain?

Chains for 11-speed systems are around 5.4mm wide on the outside, vs. around 5.9mm wide for 10-speed ones, so that’s 0.25mm narrower from the center of the cog tooth to the end of the chain pin on each side.

What is the difference between.325 and 3/8 chain?

The three-eighths chain is a beefier saw and better suited to one that has more horsepower. It has larger teeth and a heavier duty chain, so it requires more horsepower to operate correctly. 325-inch chain for those saws between 40 and 60 cc.

I have done the same thing: 10 speed cranks on a 9-speed bike and I used the shims to install. Haven’t had any problem with them and shifting is excellent. So just use the 10-speed crank with the shims and you will be fine.

How many links does a 9 speed chain?

Generally 6-7-8 speed chains are the same and 9 speed are thinner, more than 9 speed is a bit specialized. The length isn’t as important because you will usually have to shorten the chain to fit your bike. The standard chain is 114 pins ( 56 links ) but you almost never need to know this ( I had to look it up!).

What does 9 speed bike mean?

When magazines and websites talk about a bike’s ‘speed’, it’s a reference to the number of sprockets. A bike with three chainrings and nine sprockets is 9-speed, even though it has 27 theoretical ratios. The higher the sprocket count, the more expensive, smoother shifting, and lighter weight the gears.
