We were talking about it in some other thread but I tought others could benefit from it if we could have that on a new one.
I gave up contacting someone that (apparently) could make arrangements to create a custom, long seatpost with a OD different than 34mm. I left several messages, talked to 2 different people but never received a call back.
If anyone else feel like pursuing it,
Here is the link. I never tried e-mailing them though, so it may be just me and my old fashion communication methods.
Good luck,
Rafael
