I am 67 and have always ridden a mountain bike - most current circa 89 / 90 Giant Iguana. Never had any real problems and just finished approx 800 mile tour with it. Probably just getting itchy for a new bike.
I have never had a "Road Bike" with "skinny tires" and am thinking about checking some out. My only reservation is the drop handle bars - not sure if my old framing (6'1") will survive long rides on drop bars. I currently use a butterfly bar that has about a 2" rise at the ends and have added the bar ends to give me more hand positions.
Any others who have gone to the drop bars after years on mountain bike bars? How rough was the transition???
My average speed cross country for 800 miles was about 12 mph - rear panniers, on solo tour - am wondering if a road bike would speed things up any??
