Largest offset on carbon seat posts

[Kurt V Scholtens]

Hi Group – I’ve recently figured out my 27.5 offset/set back on my ritchey carbon seat post is no longer adequate for my needs.  I find myself scooting/shifting backwards to the back my saddle constantly.  After I took to local bike shop, Fitter demonstrated plumb is off significantly, though I know there are some other things that can impact (stem length/offset, seat height, etc).  Since I’m not ready to go get full fitting at this time, or get a new frame, anyone have recommendations on their favorite big offset carbon seat post?  I am talk 40mm or more.  I understand these are hard to find.

Thanks in advance,

Kurt,

The biggest seat post offsets I know of come in alloy posts:

1) The Nitto S83 “frog” seat post, which has 4.0 cm of offset

2) The SR MTE-100 adjustable-setback post, which has 5 cm of setback:

If you try the SR MTE-100, swap out the quick-release mechanism for a standard metric bolt to 

reduce the likelihood of breakage — the QR is more delicate than I would like.

(I think it is a 6mm or 8mm but am not certain.)

As soon as you can, get that professional bike fit and look into a different frame than your current one:

You will be much more efficient, more comfortable, and happier riding a bike that truly fits you: I spent decades 

Trying to get normally-proportioned road frames to work with long stems and big seat post offsets before finding 

frames that really worked for me (50-51 cm ST x 54-55 cm TT, CTC). (I’m 67.) Don’t wait.

This product, the Rinsten Spring, looks very interesting. As one who is 6'4" I have setback problems too. It would solve your problem, though it weighs 337 g.
