I took the old cannondale for a ride to the woodlot 30miles on the tar but I took the back road called the mountain road [up and down hills]A long story short I was happy with my condition and the ride on that old bike[that started as a L.L.Bean Countryroads 30 years ago and one of there mechanics changed It from a 12 speed to a 21speed mtn bike [thy to find a mechanic to do that these days.///My jeep is hung up for off road,it was a long bumpy ride home in the traffic./Kenneth
