Since we are talking about tubing, does anybody know what these fork blades (Reynolds, I presume) were called: They start out oval and big (like "normal" blades) until about 1/3 of the way down. Then they quickly transition to round and very, very thin. Leaning on the bars of a bike with these gives visible fork blade flex (front wheel moves forward), and the ride is very comfortable.
These were used on some French bikes (notable A. Singer) until the late 1970s. Does anybody have a set of these blades for sale?
