Following this thread because I have the same experience. Getting back into biking, like, seemingly, half of the country
and my FX4 feels uncomfortable even on a 20 mile ride. After about 5 miles I get numbness and tingling in my fingers and the reach seems long; also get numbness on my perineum at about 15 miles.
So have adjusted (rotated up) the flippers (or whatever they are called) on the Isozone ends, a few degrees, making them feel a little better, but not much. Am considering replacing the stem, but because I am such a noob, I am not sure what a I really need. Would an
adjustable stem work?
As for the seat, have ordered a
Berthoud leather saddle with a cut-out. Fingers crossed. It's pretty expensive, and there is no way one can predict if it's going to work. With the current saddle, my dick feels like it's gonna fall off, but at least it's gonna go out in a blaze of pure French esthetic glory, if the Berthoud saddles don't work either.
