Negative... the 4 points of an X ring are as effective as your fork seals in
separating external and internal fluids and don't require lube...
You can submerge the chain into a sea of oil and not one molecule will migrate
pass the effective X ring seals held in tension to lube the seals...
Currently we have the X rings designed out of the new fluoroelastomer
product known commercially as Viton or Kalrez and reasons are:
1)Excellent Resistance to Drying Out
2)Low Drag
3)Seals at 4 points
4)Grooved Reservoirs of Lube
What that means for us is the fact Viton or Kalrez X rings will be
100% serviceable far beyond a chain's first adjustment mileage point
where metal to metal wear begins to happen at the critical pin and
roller junction...
If you wish to lube reach the critical pin and roller junction just
remove X rings with razor knife...
