I double-checked, and the difference is actually 75 g, not 50. To be more accurate, the Nishiki frame weighs 160 g more than the Raleigh, while its fork is about 85 g lighter. My point was simply that the Infinity tubing is probably not that much heavier than the Reynolds 531C. And I have no idea how any sort of as-built weight variation information could be compiled at this date: the bikes we have available as a sample are different models, from different years, constructed in different sizes. Too many variables!
