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.
- Lift the chain off of the front chainring. Shift your gears into the smallest cog on the rear and the largest chainring in front, then life the chain. If you notice a big gap between the chain and the chainring it’s probably time to start shopping around for a new bike chain. If you have a ruler handy, measure your chain with a ruler.

How do I know what bike chain to buy?
For measuring the length of bicycle chain size, you need to do the following: Count the number of teeth on the biggest front sprocket and largest rear sprocket. You can find the numbers printed on the sprockets too. Next, you need to measure the distance between the crank bolt’s rear axle and midpoint.
How do I know my chain size?
To determine the pitch (chain size), you’ll need to measure the distance between any three consecutive rivets, then divide the result by 2. The rivets are the small, round pegs/studs that hold the chain segments together. Measure from the first to the third, then divide that number in half to get your chain pitch.
How are bike chains measured?
Measuring for chain wear is done with a chain checking tool or accurate ruler/tape measure. Using a ruler, a new chain should measure exactly 12 inches across 12 links, from middle of pin to middle of pin. The number most commonly agreed on for a worn chain is one percent elongation between links.
Are bicycle chains universal?
All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. However, this does not mean all makes and models of chains are interchangeable. There are two basic types of bicycle chains: “one-speed” chains, and derailleur chains.
How much does it cost to replace a chain on a bike?
How much does a bike chain cost to replace? Entry level chains can start off around $15.00 with more expensive and higher performance chains ranging from $25.00 to $60.00 or more. More expensive chains increase shift quality and are generally more durable as they wear.
What size chain is bicycle chain?
The chain in use on modern bicycles has a 1⁄2 inch (12.7 mm) pitch, which is the distance from one pin center to another, ANSI standard #40, where the 4 in “#40” indicates the pitch of the chain in eighths of an inch; and is standard 606 (metric) #8, where the 8 indicates the pitch in sixteenths of an inch.
What’s the difference between 40 and 41 chain?
# 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.
What happens if bike chain is too long?
If the bike chain is too long it will cause problems when changing gears as you shift gears and the derailleur can’t pick up the extra chain length. As a result, the chain may keep slipping off. Your front and rear derailleur are not properly aligned. The chainring, derailleur, or the chainring are damaged.
Is it OK to use wd40 on bike chain?
You can use WD-40 Multi-Use- Product. It is a water based lubricant that provides the right amount of lubrication to the chain lube. WD-40 is a great bike chain lube water based lubricant and will not only lubricate the chain well, but will also keep it rust and corrosion free.
When should I replace 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.
