Here is another for you. Background. In order to be able to take them on airplanes tandem bicycles are often made with stainless steel couplers than can be unscrewed to take the frame apart. Adding the couplers to a tandem add between $1000 and $2000 to an already multi thousand dollar bicycle. Stainless steel is prone to galling and having a coupler seize makes the bicycle unridable and results in a very expensive repair.
The manufacturer of these couplers has put a lot of effort into finding lubrication that best prevents galling. After testing over 100 products they recommend using Finish Line™ Extreme Fluoro Grease. The attached link explains their findings. <http://www.sandsmachine.com/grease_t.htm> When you look at the kind of things they design and manufacture you get the feeling they know what they are talking about <http://www.sandsmachine.com/s_about.htm> Disclosure: I and many friends have bicycles with their couplers but have no financial interest in the business or the lubricant.
