ichi bike said:what about going the other direction i have a new 1and 1/8 frame that i would like to but a 1" threaded fork
is that possible
That's what we're talking about (or at least what I'm talking about). I'd imagine it would be doable, as long as you can adapt the 1" bearing cups to the 1-1/8" head tube. Pressed in spacers would make the most sense to me. Or an alternative would be to have a crown race and upper cone that fits on the 1" steer tube but works with the 1-1/8" bearings. Seems like the first option would be easier.
