An off-list discussion with another listmember pointed out that in 1981 Nishiki (actually Kawamura built) used "Colnago-like" fork crowns on their Professional model and "Cinelli-like" fork crowns on their next model down. After reading the fascinating discussion about the development & dimensions of Reynolds and Columbus fork blades this week, it got me to thinking. How did the industry approach the size and shape of different fork blades as it relates to fork crowns? Does the framebuilder have to reshape the fork blade to insert into the fork crown or is that a fairly standard dimension? Would availability of fork crowns have influenced the changes to fork blades? Colnago introduced their microfusion fork crowns in 1969. Would this have had anything to do with the changes made by Columbus about that same time? Lou Deeter, Orlando FL
