What are chains?

A bicycle chain is the most fundamental, most important, piece to a bicycle. It provides the rider with the ability to move the bicycle to any speed so long as the rider is pushing the pedals. The chain transfers power or energy from the the rider’s exertion to the pedals. Then from the pedals to the chain and from the chain to the tire. This process then allows the bicycle to move.

Why are chains important?

The chain provides the functionality of movement to the bicycle. Without a chain, the bike would not move when pushing on the pedals. The bicycle chain gives a 98.6% chance of efficiency. This means that 98.6% of the time that you push on the pedal, your bicycle chain will work at its most efficient state. This can give you the most speed and better travel time.

How do chains work on a bike?

The bicycle chain acts as a bridge transferring energy from the person to the pedal and through the chain to the wheel. This process then allows for the movement of the wheel.

How do you choose the right chain for your bike?

**Keep in mind. Some chains you order may be longer, have more length, than is needed. Shorten the chain by removing some of the links.**

Recommended Maintenance for your Bicycle Chain?

It is highly, overtly, recommended that you keep your bicycle chain clean of dirt and debris. Keep the chain lubricated at all times(after cleaning). Chain lubricant comes in many forms. There are gels, liquids, and spray can(air) lubricants. All of these can be helpful, just depends on which you would prefer to use. Also, over time your chain can become loose. Keep your chain comfortably tight. You can also shorten the chain, if need be, by removing some of the chain links.

When to replace my bike chain?

If your bicycle chain is loosing its chain links and falling apart, you should replace it ASAP. Nothing hurts like when your chain shatters off of your chain ring and you either go plummeting to the ground or abruptly land on top of your bicycle with large force. It hurts. Another replacement indicator is when your chain is constantly slipping off of the chain ring, causing you constantly to put it back on.
