I also have a 650 wheel lightning. With front and rea brakes, pedals, cage and drop bars, and Rolls saddle it weighs 16 lbs. It is a rocket and doesn't beat me up on Texas rough chipped sealded, wash board roads. My other bikes are a geared custom steel and a Lynskey Ti Helix. The Wabi scandium is just as smooth and a ton cheaper. But I,ve been riding the Wabi mainly for long, hard road rides through rollers and not casual rididng in town. The Classic should be more durable and subject to more abuse. I take as good a care of my bikes as I can and short of crashing out the frame the scandium will hold up fine for me and is 2-3 lbs lighter. You might ask Richard why he discontinued the scandium frame for light steel. Was is cost or low sales? Every thing I've read about the scandium frames have been positive from owner.
