I have a magenta 91 hahanna that i saved from a skip. The seat post and saddle are shot and the handlebars seem to weigh about half the weight of the bike.
What diameter is the seat post?
What diameter are the handlebars at centre point?
Can the bike be easily converted from a Project 2 rigid fork presumably 1 1/8" thread to a set of shocks and an Ahead Stem?
Thanks

The handlebars are the normal 25.4 type and the stem is a 1 1/8" quill type.

If you change out the entire fork, headset, stem, and most likely the brakes you can run threadless.

The seatpost will be a bit of a trial. In the old days there were some changes made as the bikes were produced in the season and the seat tube is one thing that did change. You need to find a shop with a guage to drop in the frame, like the one in the picture here. You can't use calipers to check this fit just in case you have a set.

I read that post size as either 26.0, 26.4, or 26.6.
