Thanks guys for all your responses. I don't plan on competing any bike races, i just want to stay fit, ride, and enjoy it. it's been awhile that i've weighed my bike, but i estimate between 20-25 lbs (87-88 centurion le mans). my neighbors' bikes are weighing under 20 lbs (orbea, fuji, cannondale, and felt.. 3-4 years old these bikes.).
