I fitted a 130mm stem...it feels right to me and I am proper stretched out..the front hub is out of sight when I am on th edrops but I can see it when I am on the hoods...previously on the 120mm stem I could not see the hub in either position..does this matter??????:ohmy:

Is it comfortable ? If so why the concern ?

It's a starting point. If you're comfortable with the position then it's not a problem. I have problems being too stretched out with my current stem and suffer over 50 miles +.

when I got fitted this was one area I choose to discard. For me its all about what feels right over long and short distances. I can see me hub and all is good !

This front hub visibility thing is a load of old cobblers in determining whether one's bars are at the right distance from the saddle.

There are too many variables that influence the relative positions of saddle, bars and front hub and the viewing angle of the hub:

Neck length
Femur length
Most efficient/comfortable fore-aft position of saddle
Arm length
Head tube angle
Fork rake
Flexibility of back
Limb/torso/neck ratios

As an example, my position is very similar to Jean-Francois Bernard's - i.e. very stretched out but very stable and comfortable and ideal for both climbing and descending. Although my frame size and stem length are in perfect proportion, my limb/neck/torso ratios mean the bars therefore appear several centimetres in front of the hub, and using a straight edge on this photo you can see that so are J-F B's. Some riders use a far more upright position - it's all dependent on the factors listed above, so there's no point relying on the hidden-hub 'rule'.

Your arms should be shoulder width and with a small bend in your elbow when on the hoods. Thats what I'd concentrate on rather than being able to see the hub.

Whats feels right probly is right. My road bike stem allows the small bend, my fixed has me riding with near straight arms and leaning forward. I can say form my experience, the later is less confortable for extended riding. However its like this for a reason so I wont be changing it.
