Anyone done this or had it done?
certainly.. but how does that help you?
ship it out and Ill find people to do it. LBS has some Threading dies , but not a whole <C> frame Prep kit
like I expect JDT has ..
you have a bike shop on every corner and a bunch of frame-builders in PDX
go forth and get it done.
I have a fork that I got threaded a lot longer than I needed .. if I were to do it again
Id use a Mix Match . threadless headset and just thread the steerer very top,
a thin thru threaded Nut and the top lock nut would secure the whole deal ..
My use was a Touring bike, so like higher Bars.. .. as I gather, You want a Classic Race Bike look..
And, anyone know of a carbon, disc, 700C, roadbike fork, with tight clearances
(not some bow- legged cyclocross thing), with a 1" steerer suitable for threading?
this is where you hire a Custom Builders help , you need a steel steerer tine to make the threaded part Work
weight weenies want all Carbon fiber , these Days steerer and all
something using an Aluminum fork crown and bonding in a couple Carbon Fiber fork blades of round tube can be done ..
just dont as how much , the one off nature of a market of just You will push the cost Up.
