Last September while riding in the Sierra Fall Classic (out of Mammoth Lakes, CA), I hit my all time high of 56.2mph while desending from Sagehen Summit. Altitude was 8,000+, and I was coasting into a quartering headwind on my 1988 Miyata 215ST.
The bike weighs about 26-27lbs, I weigh 230lbs, and the air was thin. Gravity had its' way with me...
