My question is regarding the fore/aft road bar position. I have everything else set to all your recommendations (with success). I've been told two ways. The first: when seated with hands in the drops and elbows slightly bent, looking down with only your eyes not tilting your head, the bars should intersect or block the front hub. The second: when seated with hands in the drops and elbows slightly bent, looking down tilting your head, the bars should intersect or block the front hub.

The short answer to your question is 'neither'. Why would you suddenly need a longer stem if you got a fork with more rake? Why would someone with stubby arms and a long neck need a long stem? The bar-blocks-hub concept is a quick and easy way to get close for most riders, but not a good way to settle on a final stem length. In the old days we said that if you placed your elbow against the saddle nose and your finger tips reached the bar, that was a touring fit, if there was a 2cm gap, that was a racing fit. There are lots of these fitting tricks, (knee ‘over’ pedal spindle, whatever that means, fixed knee angles at full extension (with the ankle at what angle?), back part of bars (which you never actually use) horizontal) that sound good but come up short when you try to apply them to a wide variety of riders.

Neither method you mention has any merit when applied to a large range of riders. There are too many individual and equipment variables. Just to mention equipment for a moment; if your bar has a longer or shorter reach (and the current range of road bar reaches is nearly 25mm) then you will need differing stem lengths for the same reach to the drops. This will move the relationship between top of bar and front hub but not alter the riders position in the drops. If you have a steeper or less steep head tube angle, or a fork with greater or lesser offset, then those differences will also alter the relationships between top of bar and front hub without necessarily changing rider body position. So forget what you have been told.

After reading many of your articles on fitting and leg length discrepancies I thought I needed to drop a line. Most of the posts deal with short lower legs however in my case I have a 5mm short left femur and 3mm short left tibia for an X-rayed total of about 1cm. I'm a 25yr old cat 2 racer logging about 650hrs per year. I have excellent flexibility and core strength. My hips are relatively stable in the saddle to do my body compensating for leg length through changing leg angles such as heel drop.

1. Chronically tight left ITB and left lateral hamstring and tissue between ITB and hamstring. This required weekly deep tissue massage to prevent maltracking of the patella, over time these muscles begin to pull on patella and cause knee pain. Adjusting Speedplay Zero cleat to prevent toes pointing out has helped this issue to some degree as it has seemed the the left leg wants to rotate toes out which tightens the left lateral hamstring (tibial rotation).

Re your 1: The symptoms you experience are indicative of over reaching with that leg under load and probably from favouring the right leg to some degree. To explain further, we all tend to favour one side autonomically. This is usually but not always the right side. If a rider is really functional, this may be almost imperceptible but it is always there. When there is a challenge though, whether by less than ideal function, poor bike position, perhaps in your case a leg length discrepancy, or whatever else may be the problem, the tendency to favour one side becomes more pronounced. To get to the point, can you confirm that you sit squarely on the seat?

Is there an article posted somewhere where it states the different riding positions one should take when preparing their track bike as compared to their road bike? If not, then what are some general guidelines? Should you have it set up almost the same as your road, save for a slightly lower/more forward seat position? Or should it be completely different? As in a smaller frame (top tube wise/stem wise)? Any help would be appreciated.
