Update...got my fit on Friday afternoon. The guy was VERY thorough and amazingly, did pretty much the opposite of the idiot at the other shop that I paid $50....this guy started at the saddle end and very meticulously made only one adjustment at a time and only went back to make adjustments when necessary...he used plumb lines and explained proper riding posture..he actually took out about 3/4" of spacers from my stem, which really shocked me...he also moved my saddle all the way forward on it's rails to get a reach (tip of saddle to bars) of 61cm and said 60cm would be better for me....so we took off the Easton setback and replaced it with an extra Thompson I had to get the 60cm reach. Also replaced my bars with 44cm vs. 46cm. So from all the adjustments and measurements, due to my long legs and short torso, a stock bike with ~60cm effective top tube is more than long enough and a headtube of ~20cm with 3/4" spacer and a 130x6 riser stem would work fine as well...the only issue with stock will be the amount of seat tube showing (186.5cm center bb to top of saddle or 182cm from center bb to bottom of seat rail). Now for the real test...I did a 46 mile ride this morning by myself in windy conditions and averaged 17.4mph with much less neck discomfort (less during ride and not too much after (I have a pre-existing 'weak' neck). This was my longest non-stop (well, one 2 minute stop for water and pee) ride in a while...BUT, I think the biggest difference was that he explained 'how' to ride the bike...that very little weight should be on the hands while riding and that my core should be holding me up by pushing my chest out and 'rotating' my hips by arching my lower back. This was VERY odd for me as I always leaned forward a lot...it took a VERY concious effort to do this during my ride, but it did relax my neck and forced me to use my core (core muscles in back and abs) to hold myself up...I could actually ride and kind of hover my hands just above the hodds and not fall forward and keep pedaling...ODD, but very affective...I won't lie, I wasn't exactly comfortable, but the discomfort was more acceptable and can tell as the necessary muscles strengthen, I will get more comfortable. Good news is that if I want, I can actually consider stock bikes (Roubaix, Madone, Cervelo RS) when upgraditis takes over my body.....I could definetely also go custom by primarily making seat tube longer and head tube slightly longer...I need a short 'tall' bike.....

glad it worked out for you--one thing I would wonder about is moving the seat forward all that way to accommodate your reach. I'd be more concerned about getting my seat adjusted according to my position relative to the pedals and adjust reach with different length stems. You mention a 130 stem; why not just use a shorter stem?

I don't know if he checked your knee position and told you where he placed the knee relative to the pedal, but shoving the saddle all the way forward usually place a lot more weight on the hands and makes it very difficult to hover the hands above the brake hoods.

If your saddle was shoved forward to correct your reach to the bars this is very wrong. The only reason to shove the saddle forward would have been to get the knee to pedal relationship he was after.

Your 130 stem is only about 120mm long in the flipped position, so that's no big deal, but if you ever have a problem with too much weight on the hands, try moving the saddle back 10mm and restore the reach with a 10mm shorter stem.

I think you added an extra digit to your saddle height. 86.5cm I can believe.

The saddle was moved forward to get the knee in the correct location. Once the knee was in the correct location (even after adjusting cleats to fine tune) then we moved on to reach...only started messing with reach after the knee was in the correct location..which was behind spindle with pedals level. Plumb Line dropped from front of knee to SLIGHTLY behind ball of foot.

Oh yeah...I took all my spare stems with me so he hand plenty of opportunity to mess with stems (110 x 10, 120 x 10, 110 x 17, 120 x 17, 130 x 6)....I thought for sure he would have gone with a shorter higher rise stem but after explaining how the body moves and demonstrating (and making me do it off the bike), I understand why shorter and higher would not have helped me any...the whole process took about 3.5 hours..which I think was well worth it...

I would really like to see before and after pics of your bike if you got em.

Didn't take any before shots...but after is pretty basic...non offset post with seat forward on rails (about 0.5cm space left to move forward) and drop between top of saddle and barrs is about 5cm.....which is fine with me because of my long arms. Most importantly, woke up this morning with NO neck soreness...HALALUYAH!!! I can actually ride today...rare before adjustment to bike and my riding posture. I actually have NO soreness. Hopefully this will become the status quo....

Congratulations on finding someone to help you fit your "non-typical body geometry". It is amazing to me the amount of skepticsm displayed on all of the cycling boards when someone does not fit a 72 or 73 degree seat tube angle set back seatpost geometry. I learned the hard way with my first quality road bike. The LBS "fit" me with the style of the time-seat all the way back with a set back seat post on a 72 degree tube angle frame. Over the course of a month I developed a back problem that took me months to recover from. Internet was in its infancy so it was hard to get good information. I eventually gained enough information to solve my problem. Like you I have very long legs under a very average torso. To compound the issue I have relatively short femurs for my leg length. If I ever go custom I think a 75 or 76 degree seat tube angle with a zero offest post will be about right. But, until then my 63 cm Cannondale with 73 degree seat tube angle and a set forward seatpost gets the front of my knee close to the pedal spindle with a little adjustment left either way to fine tune. I am sure that a lot of people that see my bike think I am crazy. But, I can feel what works for me.

I hear ya...my Femur is also short relative to my leg length....I have loooong tibias/fibias. Yeah, it looks strange seeing such a tall guy on a bike with the seat set almost all the way up on it's rails, not that anyone has ever said anything. If anyone would, I wouldn't care because today has been my first pain free day after ride in a while....

I feel for you. Tall guys seem often to be tall in places that average height guys are average. It makes it tough for us to understand your fit problems. Being long legged but short femured is a fit problem most of us shorter guys don't have to deal with.
My first instinct was to agree with C40. It would be unusual to be long legged and have to move the seat all the way forward to get KOP and go to zero setback, plus use a 130 stem to get proper reach. For most of us this would make no sense.
But I'm not feeling sorry for you. Chicks dig tall guys. A lot.

All too true...hehehe. Well, good news for me is that I have finally found out that I CAN get a stock 61cm frame and it will fit me fine as long as I don't mind having a bunch of seatpost showing (which it doesn't). I can knock the new Madone's out of the running as with the new seatmast on a 61cm won't allow a high enough saddle and a 63cm will be too long....a 61cm Roubaix will still work, but NOW also considering Giant OCR .....Cervelo RS....Oh, if only...hehehe.....yeah, chics DO like tall guys..hehhee...my 'normal' friends used to say, "All you have to do is walk into a bar...."..hehe..if it was only that simple. I think we all agree, figuring out women is about as easy as figuring out the proper fit on a bike...TOO COMPLICATED!!!

Speaking of complicated, since you're expanding your bike search you might want to give Cannondale a look. They offer up to size 63 in some models. Once you check out the geo charts you'll know better than I if they're a good choice for you.

You probably can use a seat mast from a 63 on the 61 (it may be longer.) I did this when I test road the 54cm, and used a seat mast from a 58 to get enough extension. I have a short reach, for my leg length. I tend to ride a smaller bike and use a long seatpost to get the right fit (compact bars are also a help, since once you get that much drop, a deep drop bar can be challenging.)
Maybe a LooK 585 would work. It's the perfect bike for me, I just can't afford it right now. Short reach, generous head tube. Stiff, light and Super Fast!

I would not call myself tall at 6' and you can see my thread on my fitting session here if you didn't see the thread:

With me I find with Long legs and a short torso a compact frame makes fitting on a stock frame much easier.
