Just what I was looking for! Bought an MTB seatpost for my road bike and it is too long/heavy. Thanks.

I absolutely love this project, and it's just what I was looking for. I have two questions about it though, specifically the tube. The 28.5 x 30 carbon tube measurement is confusing to me. What is the proper outer diameter carbon tube to purchase? What is the minimum length? Thanks again for your work on this project, I'm highly anxious to use it!

Thank you, the tube I used is OD 28.5 and inside diameter is up to what you can find, my tube used is 2mm thickness. The length is the longest tube you may cut, is all up to your requests. I understand there may difficult to find 28.5 OD tube and I'll change to OD 30.0 in the future.

I realize gmlenka as all ready stated it. BUT please review your instructions to include the disclaimer of Carbon Fiber Dust. It is highly toxic to everyone. And breathing it without proper respiratory protection is at risk. Not everyone will read the comments. So please include it in your instructions.

Great design BTW.

Thank you for your advise and I put Disclaimer already on my instructions.

Yes, so I'll try to add a dust collector part in the near future.

This is a very cool design. This will allow for very accurate tube cut lengths.

You will need to be very careful with cutting carbon fiber tubes though. Carbon fiber dust is really nasty stuff and it gets everywhere. You will want to have a good dust mask and an effective dust management system when cutting the carbon fiber tubes.

Thank you for your advise and I put Disclaimer already on my instructions.
