Mark M wants to know the difference between riveted master links and the generic alligator clip style. He recently bought a new chain that came with both types of master links.

Riveted master links are commonly used by serious racing teams. Their only disadvantage is that they take more time to install and require a chain breaker for removal (although some companies suggest grinding the rivet link on chains #520 and above). You also need a proper chain tool to rivet a hollow-nosed master link. The Motion Pro breaker and riveting tool is a popular choice.

The clip type, on the other hand, can wear prematurely and get flicked off when hitting rocks, roosts, and branches. Even rolling the machine backwards can cause the clip to come off if it catches on a slightly bent chainguide. This can lead to the master link and driveline being launched unexpectedly.

If you choose to stick with the clip type, it’s important to inspect it before every ride and watch for any unusual wear. During installation, make sure to run the open end of the clip opposite the chain’s driveline to reduce the chance of catching an edge under acceleration.
