Total spent is $135. The bike probably weighs about 22 to 23 pounds. I've got a picture in my signature, but it's set up in commuter mode (weighing about 25 pounds).

My other bike only cost about $1200. It's about 18 pounds flat with computer, cages, and pedals. It's got a SRAM Rival build and the wheels are Forte Titan wheels.

I used to own a 1988 Trek 1200. I bought it for either $125 or $115. After that I spent about $10 on some bar tape, and another $8 on cables and housing. I already had some pedals and a saddle. So the total cost was about $140. The bike probably weighed about 21 or 22 pounds. It was a very stiff and nice bike. It was just a tad bit too big for me though so I sold it.
