Garth,
Your interesting observation of Raleigh's adv weights compelled me to take the following fish-scale measurements of framesets (w/HS, w/o BB):
23.5" japRal Superbe 531SL....5.25 lbs 24.5" RalPro Mk V..................5.50 24.5" Stella (Columbus)...........6.50 62 cm Trek 760 (full 531)..........6.50 23.5" '71 Ral Int'l......................7.00 61cm '74 Schwinn P13.............7.50
These measurements indicate that the Mk V is relatively light and that Raleigh's adv claims are plausible.
