Subject: [CR] French Threads


Hello Francophiles,

I am wondering if a currently available M25x1 die can be used for threading french steerers, or if a special pitch or thread angle (or whatever) may be needed? M25x1.5 seems the current standard available size, although M25x1 is listed when I do a google search.

As an alternate, does anyone have a French steerer die for sale, or know of a source?

I would also be interested in a french thread bottom bracket tap setup, primarily for chasing threads,

Thanks!
