• The X-ring has several advantages over the O-ring chain including:

  • A standard O-ring, when squeezed between the inner and outer plates, deforms and has a large surface area.
  • An X-ring seal placed between the inner and outer plates twists as opposed to being squashed. This creates two smaller sealing surfaces with less friction and wear.
  • An X-ring also distorts less than a standard O-ring, and the gap between the sealing surfaces does a better job of retaining grease.

  Additionally, D.I.D. a well-respected manufacturer of dirt bike chains, that makes standard dirt bike chains, O-ring dirt bike chains and X-ring dirt bike chains indicates their X-ring chains last twice as long as their O-ring chains - roughly 20,000 miles vs. 10,000 miles.
