12cm on a road bike for early long stuff,10cm if I am racing.
TT is always as far forward as allowed.

*track bike, TT bike is pretty close, I think it's closer to 90.
I assume it's not a common fit these days, it's certainly not something you'd come to from a fit session or a Retul bike.

In correlation to body height / leg length would be interesting .. with me it's close but would not be UCI conform on my roadié with 191cm and maybe a little bit long legs .. riding Flite since 20 years ..

One reason I reduced setback over the last years and got a little bit higher therefor is my stomach, the second is getting my nose more out of the wind because of the speed and the third is a proper balance to accommodate the race geo of my Luzié ..

I am 40mm on a Fizik Arione saddle. That is with the saddle as far forward as it will fit on a ~20mm setback seatpost. I basically duplicated my 30-YO road bike setup, so I have no idea if this is a great fit. But I was very fast and won a lot of races in the day.

25mm with a Sitero on my tri bike, which gets me in the same position as the previous "conventional" saddle (Selle San Marco Aspide Tri) which was 40mm ahead of the BB...

Mine is 3.5cm ... but in Oregon, you don't have to worry about the 5cm rule! ... Unless you plan on racing outside of the state.

It's just the same as stack and reach for the saddle nose top, s = setback, h = height, l = length, L = quotient h / s ..

The constraint these days isn't the UCI, it's the manufacturers who won't make a bike with a normal seat tube angle.
UCI rules only allow me a bog standard road setup with my arms together with riser pads to stop getting too crunched up.
In that position I am nowhere near as fast as I can achieve on a Tri bike.
My fastest position ignoring rules is 75mm in front of the BB for a standard type seat and many many cm in front of maximum reach allowances.
Re: UCI saddle setback 5 cm. What's yours​? [lyrrad]
[ In reply to ]
92.5cm is a lot of reach - cool that you are experimenting with this. A normal seat tube angle and being "tall" can get you there while still being uci compliant, though.
I blame the mfrs not the uci.

I can ride compliant, just move my seat back and ride the bars high.
But that's not fast.
Simple fact is to TT well I need to be forward and low.
I can use a Adamo type seat set at 50mm behind and noseride, but quickly run into reach limits.
My arms from elbow to fingerstips is 56cm. Measure yours and tell me that it is not a penalty.
The reach rules should be calculated to the froward edge of the elbow pads or simply abolished.
If I put clip-ons on my standard setup roadbike, I have already exceeded reach rules without taking exception.
Why does somebody with arms 15cm shorter than mine get only 5cm less?
As well as the option to move the seat forward?

Longer forearms usually goes with longer lower leg.
Great for running, not so great for cycling as it puts your knees on your chest and makes it hard to make power in an aero setup.
Types like me NEED to go forward to be aero and make power.
Simple fact is, the further forward I go, the faster I go.
Why should I be penalised for my morphology?
Small people can run superman positions and be within the rules.
I'm not even allowed a decent one.

Now lets take your 25cm thing.
My standard road position is 12cm behind.
My best tt position is 7.5cm in front.
That's not dicking around with a couple of cm there.
But the whole rotate around the BB is only a little bit right anyways.
The pelvis tends to stay at the seat angle so therefore it is an entirely different position.
As somebody who has come from an open torso running background, I work better in something closer to that than a boardman knees on chest position.
As I transition to a road racer, I am changing, I don't really run anymore and sit much father back than when I first give up tri's. But as a tri guy, forward was simply faster and I still am now but not to the same extent.
If forward is not faster for a large chunk of riders, then why do a large percentage of the pro peleton sit on the tips of their seat?
Why do they put sandpaper on their seats and suffer uncomfotable positions if they do not gain from it?
Why did nearly every single rider take exception for seat forward?
Why did the UCI finally relent and let track riders go to no setback?
Ride whatever suits you, but I am Dans age and we found our way forward not through being told to go forward, but from our bodies saying give it a go, and we found it worked.
What I and others have foundis that there is no inbetween.
You are either forward or back.
No mans land in between just doesn't work.
If all you have experimented with is a few cm, then you haven't tried a proper forward setup and are probably not in a position to comment apart to confirm your bias.

I'm pretty forward, and I find myself doing it on my road bike when I'm under extreme stress (e.g. attacking or closing an attack). And my road bike is a few cm back from my TT bike from bike geometry limitations.
I still haven't figured out my track bike. It's hard with track, because BikeTechReview's assertion is correct with respect to most track bike manufacturers - they mostly stick with "traditional" track geometry that ignores the past 20 years. It seems you have to spring for a high-end frame designed around pursuit (e.g. Cervelo T4) to reach a more forward position.

My son raced USAC AG Nats last year in Louisville in the TT. On a first gen Trek SC with stock saddle I could only get the nose of the saddle as far back as even with the BB. That is with the saddle mount flipped on top of the seat post to the more slack angle. Normally saddle tip is forward of the BB. I borrowed a noseless saddle brand to use for just the one race and obtained the 5cm setback.
UCI allows one morphological exception in regards to the 5cm saddle setback OR the 75cm from BB to end of bar end shifter arc. Saddle may be even with BB OR the bar ends can be out as far as 80cm (85cm for very tall riders) but not both.
**All riders are entitled to one morphological exception, either handlebar position or saddle position. A saddle morphological exception means the saddle can be as far forward as even with the vertical through the bottom bracket. A handlebar morphological exception means the handlebars can be 80 cm from the vertical through the bottom bracket, or 85 cm in the case of a rider 190cm or taller. No rider can take both morphological exceptions.

sounds like you made up your mind a couple decades or more ago...fwiw, i've mapped out supply and demand for myself over a design space range of probably 15cm in each of reach/drop/setback over the years using a variety of tools at my disposal (frontal area, wind tunnel, field testing by power meter, humanipers, steep hills and a scale, shrugging in mirrors, math models to determine fast bike geometry, etc...). after all of that work on myself and others, i'd encourage folks to experiment and not blame governing bodies.

Saddle height is only 82.5cm and non critical at 12cm behind, and up around 86-87cm depending on how far forward but super critical, drop it 3mm and my knees will explode after a few KM.
Those numbers are for conventional seats.
Cleats are full back in road bike guise, cleats far forward in TT guise which is part of the seat height difference.
Knees are under a lot of stress forward as the bum muscles kick in early and load up the joint before it starts to open.
I am not rotating around the BB, the relative pelvis tilt is different, the relative timing of firing of muscles is different and all joint angles are different, especially the leg is much straighter.
Riding forward is almost a different sport to riding conventional road.

Yes, Darryl, if you bend over at the waist more (decrease femur/pelvis angle) while still producing the same power, odds are you will be faster.

But I cannot produce the same power with a tighter femur angle, and most pro's can't either.

7 cm behind BB right now. My inseam is long 91.5 cm. Used to have the saddle 5 cm behind BB and my knees were just about hitting the elbows! Fitter moved the saddle back another 2 cm so I'm not so scrunched up. I know what you are thinking. Front end is already pretty far forward for my reach. I have weird physiology. Maybe I'll ask slowman to get a crack at this oddball fit. Seat to pad drop is just 7 cm and I can just about see up the road. Another 1 cm lower is too uncomfortable.

I'm not sure that the saddle setback rule applies to non TT events, if it is it is completely unenforced. Here are measurements of Cavendish's bike showing 4cm of setback (http://www.cyclingnews.com/...lized-s-works-venge/). I literally have my saddle as far back as allowable on the rails and it is at 3cm on my road bike.
By have to I mean I would not have an aero position without it, or would totally wreck my back and put out far less power.
