Thanks to all of you for your suggestions, kudos, and words of encouragement. I had computer problems so I wasnt able to answer all of you until now. I took my bike to my LBS and the mechanic didn't find anything wrong with the bike. On the day before the ride, I made sure my chain was clean and lubed and both tires inflated. At this point, I have to assume that it was a combination of the wind, fatigue, and dehydration. I had a great time in the the ride and it was 197.5 miles. My ride time was about 14.5 hrs (my garmin battery died) and total time was 15.5 hrs. I didn't round it off to 200 miles cuz it was MILLER TIME! My next double will be the Devil Mtn double cuz its basically in my back yard. I've climbed Mt Diablo, Morgan Territory, Mt Hamilton, Sierra Rd, and Calaveras Rd but never all on the same day. Hope to meet some of you there. I'll be the only one riding a Cannondale SuperSix 3 (I haven't seen anybody else riding one in the past 2 yrs). This ride is about 205 miles so I figure it'll make up the difference with the Solvang Double.
