Perfluorinated lubricants (20/02/22 10:30:39)
I saw onw yesterday: lubricant for wheel axle ball bearings of bicycles. For skiers there are gliders and waxes of varying hardness for grip regulation. The ski systems are now banned, but they do give an advantage to cheaters. Cheating can only be exposed by means of analysis, and I cannot imagine that analysis is possible without heavy equipment - read mass spectrometers. So cheating will be safe for a while in spite of the ban, I suppose.
