kensington (philadelphia) to cottman (10 miles north) and back.
then over the ben franklin to camden and back the same day.
30 miles total.
all on a 1987 diamondback hotstreak 20".

and like the guy who started this thread, i too have been fruitlessly researching retrofitting gears onto my bike.

gears on a 20" for distance-riding makes sense for me, as i'm 4'11" and already have become accustomed to sitting and pedaling 90% of the time with my seat post pretty high up for proper leg extension... i just want gears so i can stop spinning so damn much on flat terrain/smoother asphalt.
