Hi everyone

Recently I had a profesional bike fit. The bike fit's me preaty well, but the sadle is set all the way to the front of the rails so the posibility for sadle brake is high.
Basicly i need a seatpost with more setback, curently run Ritchey Pro witch is advertised as 25mm offset, but after mesuring it carefuly I think is closer to 20mm.
The size i looking for is 31,6/400mm, with 35-40mm setback.
FSA makes 32mm carbon seatpost but it's only 350mm long, Ritchey makes superlogic one with 30mm ofset but is 250$...
All the other posts that I looked are around 20mm, at least this is wath factory is oficilay says. It's hard to tell from the pictures how much setback there is.
Dose anyone know a manufacturer that makes such a seatpost? all the materials are fine with me...

Thanks in advance

Syntace P6, if i recall correctly, allows for around 30mm of setback. The Thomson setback post is only 16 mm, if i recall. It is also offered in the sizes you're looking for.

Well Syntace looks like a high quality item but I'm not sure if it's got 30mm offset...
It's look more like 15-20mm....

Any other manufacturer maybe?

Nice knee-jerk response.

I'm in the same boat, although looking for a 30.9 diameter. Truvativ looks like it *might* make the cut for 25mm, but the pic provides no certainty. I'd like to see a hands-on report on the Syntace. Looks like it might make at least 25mm.

How heavy are you? I'm 190 with gear, and I have run a few saddles pushed all the way back, and did not have a problem with them breaking. Just sayin' if you can't find one with a longer offset for a reasonable price, I would not lose too much sleep over it.

Yeah, the Truvativ looks like real 25mm...

I would like to hear some first hand expirience regarding Syntace and Truvativ, how much REAL setback they can provide?

Custom made post is expensive alternative,they usualy bend titanium tube tu the degree and weld the clamp on it, I don't know about any aditional heat tretmant but it's expensive...

Sounds like your bike does not fit!!!!!!!!!!!! How about getting a frame with a longer top-tube?

That is not going to help anything. His issue is that the seat tube is too steep, and if a setback post gives him the proper saddle to bb position, then it's all good.

You may look into different saddles, too.

I really liked Terry's Fly saddle, but found that I -- like you -- had it slid all the way rearward in the clamps and needed more.

Turns out that the rails on FSA's Speed V and Rocket V saddles are in a more forward position, and therefore effectively provide me an additional amount of setback over the Fly.

Not knowing what saddle you're running, this may or may not be an option for you. I haven't spent a lot of time looking into other options or making comparisons, so can't suggest any other saddle brands with rearward offset similar or greater than FSA's.

how about 2 out of 3?
I have a Ritchey carbon 31.6, 45mm setback but only 350mm long.
I bought it , used it 3 times then the frame broke and the new one took a different size seatpost. originally over $200 I'd sell it for $100 + shipping.
if you're interested I can send pics. its basicly brand new and the clamp on this post is the best check out the reviews Ritchey WCS carbon wayback post
I went through the same quest youre on and this is pretty much it for setback
PM me if interested

What's a Thompson?

Decided to order the Alu Syntace, and hopefully it'll arrive before the new year. I'm one of those riders who could benefit from a custom frame. Short legs with a long torso means either sacrificing stand over height or ETT.

Unfortunatly my proportions are wierd, that's way I have this fit problems....

I can't use biger frame because even with this one I'm prety stretch out.

BTW I use Selle Italia Flite sadle....

I don't understand your purchase... the Syntace P6 pictured above is zero offset.

Sound like you need a new frame, sorry........

a setback Thomson only has 16mm of offset, so it doesn't meet the OP's needs. It did sound like a knee-jerk response given those circumstances

Not to mention is has a very conservative 41mm clamp length. That's good for holding your saddle exactly where you want it, but not so good for fore / aft adjustment range.

So really, despite Thomson's aggressive bent appearance, stellar reputation for reliability, and premium price, it doesn't provide much in the way of adjustment range over, say, a reliable but boring $30 Salsa Shaft (23 mm of setback).
