If you take a 27.2 Ti seat post. Cut it in half and use the bottom half.

Then take a 27.2 Glossy carbon seat post. (size as needed) then starting halfway down - sand around 1-2mm (as needed) off the outside so that the carbon fits snug into the Ti post. Epoxy as needed.

You would end up with a Ti seat post that inserts into the frame - extends up a bit - and then is carbon the rest of the way.


Has that been done by anyone here? (Or with carbon/steel/alloy etc)

Sorry I couldn't find anything in search.

This post is inspired by the Control Tech TiMania Road Bar which is Ti in the centre and carbon for the drops. [4th picture down on Godzuki26's post here]

I don't have an answer to your question, but have a question of my own: why?

Why did Control Tech make a carbon/Ti hybrid drop bar?

Doesn't matter to me- just makes me wonder if it's possible with a seat post.

I've seen some great custom parts on this site...

as you describe it, i'd say not, removing that much cf from the post will weaken it, risking it snapping off at the top of the ti section

you could internally reinforce the cf above/below that area, i.e. with a snug fit cf tube epoxied into it, but after all that it'll be a pretty heavy post with far less flex than the original ti/cf posts
