A Sram Power Link means you can break a chain without tools. It's easiest to do this on the bike if you have a 'C' shaped wire hook to connect the chain together. It's easy to make one of these from a broken spoke. A Sram Power Link replaces one outer link of chain. Prepare the chain 1/2 an inch short with an inside link at each end.

Identify where to break the chain
Before you break a chain, watch it as you wind the pedals backwards. The Sram Power Link looks different to all the others.
Squeeze the Sram Powerlink
Press the sides of the Sram Power Link to unclip it. You can do this by hand if the chain is clean. Wash the link with degreaser and rinse with water. If finger-power doesn’t work use a pair of pliers carefully.
Push the links on either side of the Sram Power Link towards each other so the plates of the Sram Power Link slide past each other and the pins line up with the bigger part of the ‘keyhole’.
