i have a gf ferrous and i think weight is just the trade off with steel frame, ebb and big wheels-im still thinking of getting another old rig frame as a lightweight racey thing but i imagine the swift will be the same as the ferrous-bit heavier lot lovelier overall than alu.
plus i think i might get a singular fork to jack up the front on the ferrous, in time* ill prob look at the ti frame. i think a test ride will sort your head
*a long time, 3 and a half years left of uni if i pass my exams
