It is possible to determine chain length from industrial drive train equations, and then cut the chain before installing it on the bike. Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs.

Disconnect Type 1. To disconnect this type of link, place one jaw of your pliers on the chain pin, and the other jaw on the open end of the clip. Then squeeze your pliers until the clip pops off. Then you can remove the outer plate and slide out the rest of the link.
