The Flight is engineered to be as comfy as a Ti bike without the excessive flex and to be as lively as steel, yet lighter weight than either. The only Ti frame even close to the Flight in weight is a $2500 sloping top tube design that will routinely ghost shift when stomped at anything over 700 watts. We know, we tested that Ti frame. Steel provides that perfect balance between energy efficient stiffness and a comfortable shock absorbing ride. The issue with steel alloys bicycle frame applications is specific density. Simply put, steel weighs a bunch more than aluminum for a given level of ride quality and performance. The largest portion of your average 40 million dollar jet fighter is still aluminum alloy.
Strengths: Very comfortable
Superlight(Mine is less than 1 kg. 52 cm)
Weaknesses: I think it's a dicontinued model.
The most comfortable frame besides a titanium frame I have ridden. Seems to turn on its own. The ride quality is incredible, it adsorbs enough road buzz so that I am not uncomfortable but not so much that I feel disconnected to the road. Great great bike! Oh and it's superlight.
