When I had my problem with the Phil Wood, I was driing down to the Santa Ana River Trail. I like to park at the baseball fields off Imperial at the 91 Freeway and ride down to the beach and then up or down the beach 10-15 miles before returning.

If you don't believe that Phil Wood breaks down under heat, perform your own test like I did. Get a piece of cardboard, and squeeze out little piles of different greases (like you were dropping cookies on a cookie sheet to bake), and put the thing out in the sun for a month. Look at it once a day, and record what you see. The Phil Wood will break down, the little pile will flatten out, and the cardboard will absorb the liquid, leaving nothing but a greasy spot. The lithium base grease flattened and changed colors. The moly pretty much stayed there, but flatten out some and seperated some. The Valvoline just sat there and looked exactly the same four weeks after the test started (didn't flatten, discolor or breakdown), even though I recorded over 14 days when the temperature was over 100F.
