Are all mountain bike chains the same size?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However, this does not mean all makes and models of chains are interchangeable.

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

You should also see two slight bends at each jockey wheel of the rear derailleur. 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.

How do I know if my bike is 10 or 11 speed?

Multiply the front gear number by the rear gear number to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike. If you have one front gear and three back gears, you have a 3-speed bike.

How often should I change my bike chain?

Do I need a longer chain for a bigger chainring?

In theory you would need one more link per tooth (but of course you have to add an even number so it would be 2 or 4 more links). Try it as is – unless you run the big front and big rear combination it will probably be fine. It kind of depends. Theoretically, you need 1-1/2 links, or 3/4 link SET.
