Finn, I would be interested in your lab oil results.
Did you hit some really gnarly speed bumps and catch 6" of air with a big BBQ load on the bike? Hardcore man!
I just went with another Berg for a little limber-up ride in the Capitol Clearcut errr.. Forest (WA) area yesterday. Wallowed in mud puddles, slid around on slimy clay, and generally meandered over big rocks, logs and roots -- a typical riding day in the Pacific Northwet.
