Aero seatpost problem
earth
Posts: 934
I don't think there is any solution to this currently but the problem is I like to angle my saddle a degree or so to one side. I don't know why but if I have the saddle straight then after about a hour it starts to get uncomfortable on one side. But I can only do that with a standard round seatpost. If I were to get a new bike I would want an aero road bike such as a Giant Propel but the seatpost cannot be twisted to one side. Manufacturers need to do something with the clamp to allow a bit of a twist.

Yeah its not really a question but I just wanted to say. There must be other people in the same situation.0 -
Bizarrely enough, I am the same: I put it down to jazzed hips caused by walking too far carrying heavy things (I know that makes me sound like a serial killer).
I'm now intrigued to see how new TT bike with an aero seat post goes.Postby team47b » Sun Jun 28, 2015 11:53 am

I'll keep you updated: I'm using aRudley TT bike and Ridley aero post, Planet X Exocet saddle, so it's a sound base to start from.
I may have to do something re pedaling action. Or man up. One of the two.
Either way, only way of finding out is to ride the darn thing as fast as I can.Postby team47b » Sun Jun 28, 2015 11:53 am

The best thing about an aero bike is that the saddle does not need to be orientated.0

Aero posts are great for stopping riders who can over fettle.
Personally, I think you have a hip alignment issue or leg length issue. If you have not, see a physio or perhaps a bike fit ?0 -

Using a Selle Italia SLR so not really a lot narrower out there. Think it's just buggered hips.Postby team47b » Sun Jun 28, 2015 11:53 am

I would think the only solution to achieve what the OP wants is to make (have made) a small adaptor which clamps onto the saddle rails but which incorporates a pivot to allow the saddle to turn. Obviously would need careful thought as you would not want the thing falling apart mid ride. Might also negate some of the aero effect if too bulky.Rose Xeon CDX 3100, Ultegra Di2 disc (nice weather)

That is probably the case and I have had a bike fit with a physio from Team Sky. In his expert wisdom he pointed out that you should first work on the body not only the bike otherwise you are just setting up the bike for a posture fault. The difficulty is changing the posture so I do some Yoga.0 -

I think the manufactures should incorporate a pivot in the clamp on the seatpost.0 -

It would add weight and therefore, put off a thousand times more people than it would attract. Not ever gonna happen.0 -
Assuming you've got a steel-railed saddle, you could always tweak it (with heat if needed) to where you need it.Condor Super Acciaio, Record, Deda, Pacentis.

i moved from a 143 romin saddle that i was measured for. Fine for short trips but anything longer and my hips would be pretty painful. moved to a 130 super flow and it has been great. less chaffing and no hip pain.
looking at the specialized guidance even with narrow sit bones, a 143 saddle is recommend.
The super flow is completely flat and it feels as though i can get into a more comfortable position.
But no saddle if perfect i guess!0 -

Er, why?
This is the first time I have ever heard that someone has not wanted their saddle anything other than straight.
Just don't buy an Aero bike or have something made for your odd requirements.
Why should anyone other than you have to pay for, and have the hassle of a 'pivoting' saddle?
Personally, I do not think there will ever be a solution to your problem, so why not manufacture, patent, and sell one if you really think that the cycle industry needs it?
You will get want you want and make a fortune.

Which means you're rather underqualified to comment on this subject, as it's a rather common practice.0 -

Fair enough if thousands of people have been riding around with saddles purposefully turned to one side without me ever having heard of it before.
I bow to your qualification on the matter.
Time will tell if this will be incorporated into aero seat posts though
I certainly would not want one that pivoted, and would probably (if only out of principle) not buy a bike with one (and definitely not a seatpost) that did!
Personally I would take up golf rather than expect to have a pivoting saddle on an aero road bike.
Then again, I live in the real world.
An adapter would seem to be the best solution wouldn't it?
You get stem risers (which are a poor in engineering terms) so a seat clamp adapter would be easy (and not a compromise in the same way a stem riser is).0 -
Actually if you have a bike fit by someone who knows what they're doing, the first thing they say to you is stop worrying about whether your saddle and bars are straight relative to the frame and start worrying about whether their current position allows you to pedal efficiently. If you're over 25 any existing physical asymmetry is pretty much permanent so the bike needs to accommodate your body. Not the other way around. I have my saddle turned slightly to the right due to a slightly rotated pelvis and my bars rotated slightly to the left as an elbow injury prevents me straightening my left arm. This was done by the bike fitter and has produced a symmetrical pedal stroke. My left knee used to rub the top tube. Aero seat posts are fine if you're 18 and still have flexy bones but for anyone over 30 they are dumb. Anyone over 30 who has been riding for a number of years and not part of the new wave will know that a good pyhsio or chiro could potentially realign. A good bike fitter could shim a shoe too, thus rendering potentially curing the hip / rotated pelvis bike issue too. Surely ? 0

Gawd, they don't have to put one on every bike they sell. :roll: Just sell one after market. Some kind of shim between the saddle rails and the clamp might work.0 -
A physio or chiro can only correct recent changes. My pelvis alignment is a result of speedskating as a teen. (always turning to the left). I didn't notice it until I was in my thirties. After that long it's permanent as your bones grow to accommodate the asymmetry. Your point about shimming a shoe is valid. The bike fitter suggested that as an option but turning your saddle does the same thing for free.Actually if you have a bike fit by someone who knows what they're doing, the first thing they say to you is stop worrying about whether your saddle and bars are straight relative to the frame and start worrying about whether their current position allows you to pedal efficiently.

Should have bought a track bike and gone to Newport. End of chat

Ever thought of going to yoga???
You'd be surprised at how tight and jammed up "fit" people's hips are...

This is an odd wish.... but logical up to a point.
How did you first find out about the need to cant the seat over? And do you really mean 'a degree or so'? That is hardly any difference at all...
But anyway.... My thoughts as follows:
1. There are plenty of bikes in the Giant Propel price range that don't have an aero seat post.
2. You can easily bend the rails on a cheapo saddle to get far more than a single degree of list.
3. As already suggested, it may be a matter of having the wrong saddle.
4. Pop a little strip of rubber or similar inside the clamp, under the saddle rails, on the side you want raised.
But most intriguing.... how did the realisation come that the saddle needed to be 'on the piss' to ease discomfort after an hour in the saddle? It may be (forgive my impertinence) all in the mind. There are so many variables with bicycle set-up and saddles are anyway so easy to move around on, that I'm sure the solution is a mere tenner - or a mere yank with a socket lever - away from you.
But I hope you sort it out....0 -

Simple, I rode the bike and got a sore left cheek after about an hour. I decided to turn the saddle slightly to the left and the problem disappeared. On occasion I straighten the saddle but after a short while the problem returns so I twist it slightly again. The body is not perfectly symmetrical. I should point out that I mean the saddle is rotated about the vertical axis (yaw) not tilted, listing or rolled which would be rotation about the longitudinal axis. That's why it can only be done with a round seat post.0 -
Get a saddle with metal rails and bend them. Do it right, and it will have the advantage that the saddle is guaranteed to be in the right offset and unable to deviate from it.0
