I was uncertain whether or not to post this in the mechanics forum, but I trust that this group can help... Need a 26.6mm, 30mm setback seatpost.

Background:

I'm adjusting the fit on my 24 year old daughter's 1999 Bianchi Volpe. She has a rather unusual body type, being long of torso. She's a good fit on the bike generally, but when I ride beside her, I get the sense that she needs her balance point rearward just a hair. The bike is stock, with a 26.6mm seatpost that has a laprade type single bolt clamp. The setback isn't very much, maybe a standard 15mm or so. Saddle is Avocet Touring II ladies, so you know that the rails are short as is the nose. She likes the saddle okay.

I'd like to set the saddle further back from 15mm to 30mm. I've seen plenty of seatposts at 27.2 with setback, and a few with unspecified setback.

Some Progress:

On eBay, there are UNO alloy (in various colors) MTB seatposts in 26.6 that appear from the images to have ~30mm of setback, but it's tricky judging from a photo. Naturally, the listings do not specify.

Request:

So, does anyone have some specific seatpost recommendation for me to look into?

Thanks,
Phil G.

The UNO SP-248 seatpost is available in many sizes from VeloOrange at a nice price, although curiously 26.6mm is not one of them. They say 24mm of setback. I've been looking for longer setback posts in 26.8mm, apparently common on older Japanese bikes like my '79 Miyata, and this is the best I've found so far. Because of the arc for the seat clamp, the setback changes with saddle tilt.

VO's Grand Cru Long Setback post (30mm) is a beauty, and easy to adjust with two bolts, but sadly only in 27.2mm.

Thanks. That one looks similar to the clamp/head on the Kalloy/UNO one on eBay, which they call an MTB post. It comes in several anodized colors, too. I may have to try one just to see what the advantage is. It might be that 10mm is enough improvement, but I would've liked 15mm additional instead.
