Setback seatpost(18 posts)

Setback seatpostjaredhartman
Mar 16, 2002 9:05 PM
My saddle is positioned as far back as I can get it, and I still feel cramped. My legs just want to be further behind the pedals. What setback post will give me some real setback? The thomson looks like it doesn't really offer much because the clamp isn't setback from the actual post. It is placed directly on top. Titec makes a MTB post, the hell bent, with a lot of setback, however it is quite heavy. Any recommendations would be greatly appreciated. Thanks
Campy Record Ti .... lots of setback ..CT1

American classic two piece is good on setback also.

The AC is really a better post because it's got a cool micro adjust.

You can also mod the clamps on most posts which will give you an additional 1+cm of rearward saddle adjustment.

Campy Record Ti .... a pic so you can see how much setback.Spirito di Finocchio

sorry its a crappy pic but...

from my experience the setback is middle of the road...there are other posts that offer more.

if you are cool with the lepper then i would keep it as a good seat is hard to find.

hope the pic helps you get a better idea. my saddle is set forward and could only go about another 10mm forward just to make it clearer fro you even tho you will be going the other way.

i quite like the post as well and havent had any probs. it looks nice as well.

compare it with your setup and see

Thanks for the picture. I found a pic myself, and the two confirm that the Campy post wouldn't really add much more than mine now. If you look at it the clamp on the Campy, it starts right above about the last quarter of the actual post. My post now starts right in the middle. I need to get the saddle back so that I am not sitting on the rear steel bridge. I have't seen any posts, with the exception of the Look (too expensive for my fixed gear). I think I am just going find a saddle with more rear padding.

I had my saddle MUCH farther back than the one in the pic. Sooooo far back in fact that I had 2 1/2 inches from the nose of the saddle to the vertical line through the BB. Check this same measurement and see how it compares. This was with a SI TA saddle.

Anyway, the clamp on the Campy post is much more rearward than most posts. It's also easy to modify this post for an additional 1cm of rearward adjustment. I'll take a pick sometime later in the week to show you how I did that.

YMMV

actually have to agree with CT1Spirito di Finocchio
Mar 17, 2002 10:34 PM
had a look at some other seat posts and apart from the look (pricey) most that i saw didnt really offer much in the way of setback compared to the campy item.

in particular the thompson with setback offers little actual setback as the clamp looks right on top of the post anyways.

as you can see from my pic i could have done without the campy posts setback but admittedly i fell in love with its svelte appearance...;-)

im sure youll find something - hopefully it doesnt cost a packet.

think of the bright side it could have been a brooks with even less rearward rail travel.

how is the lepper saddle anyways - ive been eying one for a while.

Spirito,

You are probably right; I have only seen pictures of the things; you have one. I agree that the Thomson and all of them with the clamp directly on top have no setback. Thomson's attempt at setback was weak because although they bent the shaft, they still put the clamp directly on top of the tube.

I also looked at the easton CT2 on my mountain bike, and it looks like it would offer me more because its clamps start right above the very back or the post.

I still think that most road posts are close to the same. The start of the clamp is the limiting factor. My clamp starts right in the middle of its straight shaft. And, in the hundreds I've seen, most have started near the middle.

As far as the saddle goes, there is a post down the page which hass all of that information. I have decided to just get a saddle with some padding at the back. It seems cheaper and easier.

For a comparison (of seatpost setback) to work our bikes would have to have the same the same seat tube angle and the saddles would have to be the same distance from the bb along the seat tube, and, as you acknowledged, our saddles would need to be the same or at least the same length with the same fore/aft adjustment. Nonetheless, I did a very crude measurement and got around 2 and one half to three inches from the centerline. This was with a serfas ddvado saddle which has "extra long" tubes if that matters.

Anyway, I am definitely interested in seeing how you modified it. I saw a picture of an American Classic today which does look like it would offer more setback than my current post. It looks like their are two positions for the uppercalmp, one forward and one back giving at least 1 cm of adjustment. I am not sure about this however.

Look Ergo post, as far back as you can go, expensive though.

Thomson setback = slightly more than 5/8". Mine is due in a week.

How about some more data?Kerry
Mar 17, 2002 4:57 PM
Where are your knees relative to the pedal axle? The range of experience is 1 cm ahead to 2-3 cm behind (measured by a plumb line from the bony protusion just below your kneecap with the cranks horizontal). Longer femurs and the desire to push the gear suggests being farther back. Spinners and short femured people tend to be farther forward. What post are you using now? If you have a post that lets you go a fair ways back, you may have a frame with too steep a seat tube angle.

I do have a frame with a steep seat tube angle. It is a track bike which I use on the road as my fixed gear training bike/commuter. The post that I am using is the stock bianchi, which as with most posts, has the clamp starting about in the middle of the straight post. Even though it is geared relatively high, (48/16) I do like to keep my cadence above at least 90 and usually ride from 100 to 110. I feel most comfortable riding like this when I am at the rear of the saddle, which wouldn't be that bad except that the saddle is a lepper tensioned leather so I am right on top of a steel bridge. If push comes to shove, I may just get a saddle of which I can sit on the back edge.
Raceface?gtx

lots of options, and many can be found here

I have looked at raceface; their XY and prodigy offset give 1" of true offset. I have also looked exhaustively at cambria's road bike selection of posts. The mountain bike page does seem to have more posts with greater setback.

Kalloy has more setback...C-40
Mar 18, 2002 10:08 AM
Take a look at the cheap Kalloy. It's got a little more setback than most tradidtional road posts.

You might also consider a saddle like the SDG Comp Ti or one of SDG's cheaper steel rail models. The rails allow the saddle to be moved significantly further back than most.
Look Ergo Postpmf1

Probably has more fore and aft adjustment than any seat post out there. Its expensive, but looks cool.
