Cleaning the rear wheel

[BusyLittleShop]

Thanks BLS, always wondered/felt the "warning" about using magnesium wheels that are older was not so much of an issue.

You're welcome Bonz... I think technically speaking the reduction in
unsprung weight is worth the extra care of running Magnesium wheels...
when I test hop a customers RC45 equipped with stock aluminum wheels
the 6 lbs difference is sure noticeable during acceleration and during change
of direction... the light feeling of Mags will spoil you... there is no going back...

Do you use GL-4? GL-5 seems stinky at best and risky at worse.

GL5 damaged the O-rings on a DID chain. It had done a decent mileage so I can't complain, but I won't use it again.

I'm sure standard 90 gear oil as recommended by most chain manufacturers will be fine.

What happened--how'd they fail?

Negative... GL5 is an petroleum product and will not damage seals...

Technically speaking the old rubber O rings are no longer employed by
chain manufactures and the reasons are:

1)Poor Resistance to Drying Out
2)High Drag
3)Sealed at only 2 points
4)No Reservoirs of Lube
5)Fragile stuff

Currently we have the X or W 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
5)Tuff stuff

What that means for us is the fact Viton or Kalrez X or W rings will be
100% serviceable far beyond a chain's life...They have a excellent
resistance to most chemicals including petroleum products... most
important it doesn't need protection from drying out because the
groves in the X rings hold reservoirs of factory install grease...

Thanks for this. So a chain manufacturer such as D.I.D. for example, uses Viton or Kalrez for their X or W rings?

You're welcome... and yes D.I.D. employs Viton or Kalrez for their X or W rings...
