Help! Where to find 25.4mm seatpost with >20mm setback?velobear

Any help in finding a 25.4mm seatpost for a Vitus would be greatly appreciated! Currently have about 15-20mm setback, but looking for just another 10-15mm. Not having much luck with most bike shops. Thanks in advance for any info!

There is no standard for measuring setback. The limiting factor is the location of the front of the seat rail clamp. Traditional seatposts locate the front of the clamp very near the centerline of the seatpost. Posts with the clamp located further back are considered to have "additional" setback.

The pricey LOOK carbon post, the new Easton EC70 post, and the Selcof bioposition post all have additional setback. Not sure if all can be had in 25.4. I know the LOOK is made in a 25.4 diameter.

The ITM Millenium post is an excellent post with about 5mm more setback than a traditional post. It is made in 25.4.

My goal is to get the saddle back another cm. The current saddle is already pushed back as far as the rails will allow. Since the saddle is a favorite, I was hoping to find a solution with the seatpost. BTW, I haven't found the Easton or Selcof biposition in 25.4. The Look I've found in 25.0, but not 25.4. I'll check the ITM. Thanks for the lead!

If all you can find is a 25.0, a .008 inch thick shim could be used to get it up to size. Not the greatest approach, but you've got a real odd-ball size there. I forgot that LOOK frames were 25.0.

What post are you using now?

I've got the stock Vitus post. There's no name on it. The bike was originally purchased from Colorado Cyclist >10 years ago. Most recent email to Sheldon Brown indicates that it might actually be a 25.0mm. Thanks again.
