today i rode 51.4 miles from San jose to Menlo park and back to Palo alto. The weather was 54F sunny with light winds. i changed my current setup with the panniers and trunk bag to a backpack setup. Also i replaced my worn out chain at 1700+ miles, and i rotated the tires around. The squealing sound that it made for over a thousand miles actually came from the rear hub, my friends at the LBS put some penetrating oil and fixed it.
