Reality check: XC mountain bikes don't even weigh 20lbs and 23-25lbs is considered light for the $2000 you are spending. How do you expect a steel, sub-$400 bike to weigh under 20lbs?? That's lighter than alot of road bikes!
If weight is an issue, than this is the entirely wrong kind of bike class for you. A NEXUS hub, steel tig frame, durable big tires, seat and cromo handlebars and a good price. And you are going to complain about weight?
