I have a 2009 Fuji Crosstown 1.0 and am slowly turning it into more of an upright position road bike. My question is will a Fuji FC-770 carbon fork fit this Altair 1 frame that's on this bike? The frame is a large (19"). I think it will, but don't know if it will require any mods to the fork (cut to a different length, etc.) Also wanted to know if the existing stem and head tube will work with that carbon fork or if I need to change those out too.
