I need a 27mm CARBON seat post for old track frame.??
Not too sure what forum to post this in....
But I am looking for a carbon seat post for my late 90s Italian built pursuit frame.
I really want a carbon for weight issue.
But can not find one anywhere..
I need a 27mm exact or anything below (as I can use a shim).
Does anyone know anywhere I can get one??

Reason: Modified the "wanted" ad.
27.0 is an old standard that came about before carbon seatposts were being produced. So, the two eras never really overlapped to my knowledge. But you are in luck. You can get a Thomson seatpost in 27.0. I have a carbon seatpost sitting in my toolbox and instead I use my Thomson. The weight difference is miniscule but the strength difference is significant.
You can't go wrong with a Thomson seatpost.
If you want to shave weight, cut the excess post from the Thomson after you get the saddle height set.
Why not just ream your seat tube to 27.2?
Consider USE, UK, they make 25.0 posts and shims, 0.2mm increments, to 27.2,
and a 27.2 post and shims to larger than that.
AlAn, frames used 25.0 posts shed the frames,kept the seatpost.
bought USE shim ,a 25>27, so I fit it onto my RB1.
Hurry, the aluminum ones are in the close out store http://shop.use1.com/category-s/91.htm
