The Marathon I had didn't really fit me so I had sold it to a good friend of mine, who is much taller and suits it better..
I found this Caliente for $30 so it fits me a bit better, i bought a donor Huffy road bike which had the Araya alloy wheels, drop down bars.. the frame little heavier though than the Marathon.. even with the alloys and new tires it weighs in at 27-28lbs. It'll be mostly for university commuting though, and its flat here so no worries there, as long as it can take the abuse.
