My Wabi Lightning 55 cm (the no longer made, sorry OP, scandium frame) weighs 13.7 pounds with a front brake and bottle cage. I used Novatec hubs (road front) to Kinlin XR 300's and bladed spokes (32R-28F) to build the wheels and a smattering of excellent price-to-weight ratio parts. The only downside is the torturous saddle that doesn't let me make rides longer than 40 miles.
