Warp 9 EK 520 MX Chain

An EK 520 roller chain in gold, supplied at 120 links with a clip style master link. It is a non-sealed standard roller chain rather than an O-ring or X-ring chain, so it runs with less drag and needs cleaning and lubricating more often.

The outer plates are gold and the inner pivot links are black. Pins are quad staked. Count the links against the chain coming off the bike before cutting this one to length, and check the rear sprocket and the front sprocket for hooked teeth at the same time. A new chain on worn sprockets wears out quickly, so the two are usually replaced together.
