Devon,
The fork stiffeners is a misnomer to start with. The "fork stiffner"
is for looks for the most part. Round fork blades for
road bikes need to be heavy gauge. .9 or 1 mm or heavier. Round blades
like that are (were) made by Columbus is 22.2mm diameter and by
Reynolds in 22mm diameter. Not all 22.2mm round blaqdes from Columbus
are heavy gauge. One must find round SP chainstays or the heavy
Reynolds blades to have a chance. Here's a trick. Standard Columbus
oval blades can be re-rounded at the top and will fit into a 24mm
round fork crown.

Brian, do you have an opinion about the use of round blades with long tangs for a road bike? for a light rider, might that possibly mitigate the "issues?" or would that not be enough support?
