The chain can be used for 10 speed bikes, and it can be used with all SRAM cassettes and chainrings in order to make sure that the shifting operation is smooth.

One thing that you should remember is that this particular bike chain does not have any corrosion resistant coating. It does have nickel plating, but you should be very careful and ensure that you lubricate the chain frequently.

Best Bike Chains Buyer’s Guide

What is a Bike Chain?

Not all cyclists know about the individual components of their bike. You may be getting some miles in on your bike and may not even be thinking about how all of the parts of your bike work together. You may not even notice your bike chain is there until it stops working. 

A bike chain is the thing that is responsible for transferring the power that you put onto the pedals onto the wheel of the bike. This means that the harder you pedal, the faster your bike will go. 

Kinds of Bike Chains

There are all sorts of different bike chains on offer, and the option you choose is largely going to depend on what exactly you’re looking for. Here are the different bike chains that you may find when you’re on the hunt for a new bike chain.

Speed

There are 6 different speeds of bike chains available, ranging from 6 up to 11.

The chain will move up or down on the sprocket as you shift gears in the bike. Essentially, the more gears and thus speeds you have on the bike, the more narrow the width of the bike chain will be. 

You can usually use the same speed bike chain for any kind of bike. It is, however, very important to make sure that you match the right speed chain to the speed of the bike to make sure that you have a good fit and the best functioning. 

There are a few different speeds available. First is the 6 speed bike chain. This is the widest bike chain and it measures a width of 7.8mm. The next level up from this is the 7 speed bike chain which measures a width of around 7.2mm, then there’s an 8 speed bike chain measuring a width of 7.1 mm. 

From here, the next level is the 9 speed bike chain measuring a width of 6.6 to 6.8 mm. Then, there are 10 speed bike chains, and some 11 speed bike chains.

Types of Bike Chain

Road Bike Chain

When you have a road bike, you want to keep things as lightweight as possible. Of course, bike chains are a pretty small part of a bike, so you may be curious whether the weight is even that important. It largely depends on your own preference!

If you are looking for a more lightweight bike chain, you should be looking for bike chains that are made out of lighter materials such as alloy. You should also make sure that the chain is designed to be able to fit with the speed of your bike. It’s really not worth risking getting a 6 speed chain for a 7 speed bike. 

MTB Chains

Usually MTB chains can be used for either mountain biking or for road biking. The most important thing when you’re looking for an MTB bike chain is to look at the size. Usually an 8 speed chain should be able to fit an 8 speed bike, and you should be fine as long as you follow the sizing rules.

If you are a mountain biker it may be worth opting for a bike chain that is able to put up with a little bit more dirt, given the territory. You should try to look for bike chains that have special coatings or options that are easy to clean. This is because muddy and dirty bike chains that are difficult to clean may get rusty sooner and will have a shorter lifespan as a result. 

BMX Bike Chains

BMX bike chains are a totally different ball game than the other two options previously discussed. Most BMX bike chains are a little bit more narrow than the chains of road or mountain bikes, and usually measure at around 1/8th width. 

It’s still pretty important to make sure that you think about the speed when you are choosing a chain for your BMX bike. A lot of BMX bikes tend to only be a single speed so you will need to make sure that you get a single speed chain. Nothing else is going to work for a BMX bike.

You may also wish to opt for a lightweight chain if you’re a BMX rider, as this will allow you to be able to jump a lot easier and moving across terrain can be a little more simple. Keep an eye out for lightweight materials, alloy for instance, and looking for a chain with protective coating is also a good idea.

There are also two kinds of chains for a BMX. Firstly there’s the traditional BMX chain. This is the kind of chain that you most commonly find on a BMX bike. These kinds of chains feature the same inner link and outer link configuration that mountain bike and road bike chains do. They also half two ‘half links.’

The other kind of bike chain is the half link BMX chain. These chains have identical links with a thick and a thin end. On the thick end there is a standard width, while the thinner end is more like the size of the inner link of the normal chain. These chains are a little bit easier to adjust and it can be done a little bit more accurately. 

Best Bike Chains FAQ's

How do you tighten a bike chain?

Bike chains that start coming undone when you’re in the middle of a ride are incredibly frustrating. If you do have this issue then it may be that you just need to tighten the bike chain up. If the chain starts to move up and down more than an inch when engaged, then you will need to tighten up the bike chain. 

Generally, you will find that loose chains are more common on bicycles that don’t already have a derailleur. If your bike does have a derailleur and it has gotten to a point where it doesn’t keep the right chain tension anymore, then you may need to replace the derailleur. 

Otherwise, you will need to loosen the bolts that hold onto the back tire. Then, move that tire back until the chain begins to tighten. Once you have done this, you need to try and figure out what the right amount of tension is, remembering that the chain should not move more than one inch. It may be worth having someone to help you out when you are tightening the bike chain. 

How do you know when you need to replace your bike chain?

Most bike mechanics will suggest that you replace the chain in your bike every 2000 to 3000 miles, but it may be that you need to replace it a little sooner than this. Noticing the signs that your bike chain needs replacing is thus rather important.

Usually, when a bike chain starts to wear out too much, it will stretch and potentially skip over the teeth that are on the sprocket. If you notice this problem early then you may not even need to replace the chainrings or the cassette, but on occasion you may need to get new parts.

There are also a few other signs that will tell you whether you need to get a new bike chain. To start with, try and lift the chain off from the front chainring. Then, shift the gears into the smallest cog on the rear and the largest chainring in the front. Lift the chain, and if you can see a huge gap in between the chain and the chainring then it may be a good idea to start looking for a new bike chain.

In addition to this, if you have a ruler on hand, measure the chain using a ruler. Then, choose a rivet on the chain and then line it up on the zero mark on the ruler. Once you have done this, count 23 rivers, and your last rivet should be on the 12 inch mark. If the measurement is off by more than 1/16th then you should get a new chain.

Finally, you can also use a chain checker tool to see if you need a new chain. There are a number of different brands available that all differ a little but the function should be more or less the same.
