Hello everyone,
Allow me to first state that I've been using this site to glean information for my various projects and it has been more than helpful in so many cases. I want to thank everyone for being so active and helpful, even though I wasn't a member. Now that I am a member I only hope to be as much help to everyone else.

Right, on with my first post.

I have a Puch Pacifica that is a 54cm(Apx) frame. It's one of the Japanese models and I believe the material is 551? steel. I was wondering if anyone knows what the seatpost dia might be. I travel for a living and don't get to spend loads of time at home and I've negelected to take a measurement myself. I've finally decided to build this bike up, as I love it. I need to order parts so that they are waiting for me when I get home. Thanks in advance for any help in this and if anyone has any links to info on this particular bike I'd appreciate it. I'm always one to try and return a favour.
