wabi lightning se complete doe is a columbi spirit boi doe w/ crabon 1.25, worth paying for the complete, the wheelsets are supposedly purdy light too. complete bike with front and back brakes (minus pedals) weighs like 16.5 lbs if im recalling correctly? i think for a light steel frame u cant go wong with columbu spirit
Lightning if 55 cm frame is 17.5
Classic is 18.4
Special is 18.6
No practical difference among any of them re: weight. I don't know if there is a difference in how they "feel" or not. I doubt I would know th difference. Lightning has a carbon fork but steel steerer. Special is lug tubes. Frames are road geo not track but high bottom bracket.
