I have a B17 from the early 70s and a campagnolo shorty NR seat post. I was trying to assemble it last night and it appears that the rails are too wide for the clamp mechanism on my seat post. Do I have one of the posts set up for narrow rail saddles? If so, what do I need to adapt it to the B17? Or I will trade the entire (NOS) seatpost for a 27.2 that works with B17.
