Gotta love Sheldon. Here is The only caveat is certain types of Shimano chains which require special pins; they are extra-long and you break off the section after putting the chain together.
A lot of the chains you get from Walmart and other sources have a "quickie" link, a special link that just snaps the chain together. Sign up to join this community.

Pedaling in a tougher gear puts more stress on the chain, significantly shortening its lifespan. Also, avoid cross-chaining—the practice of using the small chainring and small cog in the rear, or large chainring and large cog in the rear—if you don't want to stretch out your chain.
Replacing your chain regularly can prolong the life of your drivetrain. Most mechanics agree that you should replace your chain about every 2, to 3, 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.
The easiest way to determine if you need a new chain is to use a chain-checker , which measures how badly your current chain has stretched. Although a properly maintained chain can technically last nearly 8, miles, it becomes much less efficient as it wears and elongates, says Jason Smith of Colorado-based research firm Friction Facts, with two watts of lost power for every one percent of elongation.
Find the closest rivet where the two chain ends could be joined. You will match inner plates to outer plates in order to join the chain. The rivet closest to where the chain can be joined is the reference rivet. From the rivet we add two additional rivets. This is the cutting point for your chain. It can occur that, when we pull the lower section snug, an outer plate meets an outer plate.
This cannot be the reference rivet because the chain cannot be joined here. Add one rivet. This becomes the reference rivet and from here we add two additional rivets, cut the chain with a chain tool, and the chain is sized. The dedicated 1X systems use a single front ring in combination with a wide range of rear sprockets.
Derailleur manufacturers use large rear 42 tooth and larger sprockets. These require a longer chain compared to the bikes using less of a wide range. Without passing through the rear derailleur, route the chain over the front ring and the largest rear spocket. Determine the shortest length where a chain would connect inner and outer plates.
From this point, count 4 rivets as the point to shorten the chain. This is an addition is 2 rivets 1-inch more than non-dedicated 1X system. If the bike uses a chain guide, make sure it is routed through the system before determining chain length. Using the narrow or speed chain may result in the tendency for it to fall between the two rings during a shift.
Drivetrain manufacturers design their chains to work as a system with the derailleurs, rear sprockets, and shift levers. Chains can vary in side plate shape, sizing, and height. Differences can cause variations in shifting performance between brands and models. Additionally, chains will vary in the quality of steel used.
Better chains that are more durable and longer-lasting tend to have harder rivets. Riding a bike tends to wear and thin the rivet as it is pulled against the inner plates. It does get more complex when components become mixed. As the driving force of the bike, your chain sees a lot of wear and tear.
Over time, distance and cycling conditions, the rivets and rollers begin to wear out, causing the chain links to actually stretch in length. If it is stretched even further, it has most likely damaged your cogs. There are two main types of chains — master link and connection rivet chains. Master link chains use two removable outer chain links to connect the chain , whereas connection rivet chains use a special rivet to make the connection.
The tools needed to replace your chain will vary depending on which type you have:. There are a few methods to accomplish this.
If your old chain was sized correctly, it could be used to determine the length of your new chain. To check if it was the correct size, shift the bike to the smallest sprockets, and check the chain for any slack. There should be no slack in the chain , but the derailleur should not pull back far enough for the chain to make contact with itself. Next, shift to the largest front and rear sprockets.
