Bill L questioned the 12# weight difference. I sort of missed the 12#, mainly since Bike D was stated to 'feel fast' and I assumed B & C would use heavier tubing due to the 73 to 75# load requirement and A must be thick gauge tubing given the 30# weight (Schwinns in the 1980"s used 1010 18 gauge tubing in lugged frames and quoted 30 to 32# weights).
I admit D should be about 1 mph faster than the A, B C due to the 11 to 13# weight difference (basis R Schwinn stated Schwinn tests showed 12# change in frame resulted in a 1 mph change with same effort). I focused on the 'feel fast' vs 'tested and shown faster'. I did ride a Trek 5500 (Rolf paired spoke wheels) for 5 years between riding a 1975 Schwinn Approved Voyaguer II and a 1988 Schwinn Voyaguer (touring) and both with 36 spoke wheels. I did not find it to 'feel a significant degree faster' than the Voyageur II even though it weighed less. I may have been faster, but did not feel it. However, my Norther-Lyon (36 spoke Velocity Atlas wheels) *does 'feel faster"* than either of the 2 Schwinns and is definitely easier to pedal than the other 3. So my answer is probably biased to my experiences & assumptions discussed above. Note: The 4 frames are all essentially the same sizes: 21" )C-T), 54cm and 52cm, both C-C. So tube rigidity may be more important in the smaller frame since a small frame is more rigid than a large one. This was enjoyable and thought provoking.
