Not the lightest, but real world weights
I was paying attention to weight, but not a slave to it, when building this bike. (I have a single speed and road bike for that game.) Significant savings came from E*13 crank, Marge Lite wheels, and carbon bars. Potential weight savings could be achieved with lighter pedals, stem, grips, and brakes. Realistic future weight savings may come from carbon fork and Surly light tubes. I only went the route of a titanium frame, because I could afford it and I have to work with paint quality issues all day. Current Weight: about 32 lbs.
