Quick Answer: How Often Should I Change Bicycle Chain?

How long should a bicycle chain last?

Replacing your chain regularly can prolong the life of your drivetrain. Most mechanics agree that you should replace your chain about every 2,000 to 3,000 miles, depending on your riding style. Many Tour De France riders wear out two or even three chains on their primary bike over the course of the three-week race.

What happens if you don’t change your bike chain?

Having a chain break can sometimes lead to injuries. Once the chain starts to wear, it essentially grinds on the gears with every pedal stroke; the whole thing goes downhill quickly. If the chain shows wear at 800 miles, you’ll start having problems at 1000 miles.

How do I know what chain to get for my bike?

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.

Why did my bicycle chain break?

Chains break for a host of reasons, but most common is wear. For example, if a chain has been ridden for 2500 miles, it will actually stretch out.

How much does it cost to replace a chain on a bike?

Most bike shops will charge about $30 – $50 dollars depending on the bike shop, whether it’s a popular brand or a “mom & pop” shop.

How often should I lube my bike chain?

Bicycle Tutor recommends cleaning and lubricating your bike’s drive chain at least once every month to maintain optimal performance and protection. The chain and drivetrain are typically the dirtiest parts of your bike, and this dirt is bad news for bike longevity and performance.

How do I know if my chain is worn out?

Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.

Why does my bike chain slip when I pedal hard?

Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.

Is my bike chain too short?

If the chain is too short, this shift is difficult to make and the derailleur cage is stretched out and almost parallel to the chainstay. If the chain is really short, then you might not even be able to shift into the largest cog. Before you remove the chain, make sure it’s on the small chainring and smallest cog.

How do I know if my bike chain is too long?

Do a simple check on your bike by shifting the chain to the big chainring and the biggest cassette cog; then, push on the end of the derailleur cage (pushing forward) to see how much it will move forward. If it moves just a little, then you’re good. If it moves a lot, then you’ve got too much chain.
