## 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.

## What is the right chain size?

After a measurement is obtained, its a good idea to opt for a necklace size that is at least the second size up from your neck size. For example, if you have an 18 inch neck, you should probably choose a chain length of 20 inches or more. An 18 inch chain would feel too tight.

## How do I know what speed my bike is?

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.

## What is the difference between a 9 speed chain and a 10 speed chain?

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.

## How often should I change my bike chain?

The 2,000-Mile Rule. 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 11 speed 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.

## Is a 16 inch necklace too short?

Women below 5’4” look best in 16 to 20 inch necklace lengths. A long necklace tends to overwhelm a smaller frame. Women who fall between the height of 5’4” to 5’7” can wear necklace of any length. Taller women who are 5’7” or above can wear any length necklace.

## What is the best size chain for a pendant?

For most men shopping for a chain necklace, get one that is 50 cm (20”) in length and 2-6 mm in width. If you’re adding a pendant, shop for a 55-60 cm (22-24”) necklace and 4-6 mm width.

## Is 40 and 420 chain the same?

# 420 will have more strength than the #41 chain because the side plates will be taller. #40 will be the beefiest chain in this class. This will help with thicker sprockets since there is more room between the side plates. #41 will look just like the #420 chain, but will stand shorter.
