Also, ears, nose and other protrusions can be got rid of, surely.
you should keep the nose because it warms and filters the air before it hits your lungs, but you could definitely make the whole head/face more aero... some sort of plastic surgery to push the nose and mouth forward into a dome shape... Then intergrate the eyes on the top like the windshield of a TGV...

I would say get used to it, and as Skully says, it sounds like you have the wrong foot forward (or are turning the bars the wrong way) if it is causing problems with your trackstands. Good for you to learn to trackstand both ways anyhow (if you don't already) :-)
I have massive overlap on my geared road bike, but it never causes me any problems. If I am waiting at the lights, typically the camber of the road means I need to turn my bars to the right, and then I have my right foot forward. Both feet are then a long way away from the wheel!
Moving your cleats further forward than they are designed to go means your foot will be too far back for efficient cycling and the pedal axle will be under your toes rather than under the ball of your foot.

Not sure if its because the the quill has an expander at the bottom or what but its doesn't seem right to me.... It does go quite a bit down the tube, im assuming that there is supposed to be a ridge to stop the bolt going down which may have worn out... got it off ebay so will ask thr guy if he wants it back...
Photo would help

cut bike in half ( making sure cut is made in front of bottom bracket )
weld in an extra 1.5 inches of reynold 531 into gap
weld shutproblem solved
or buy some new forks wit more rake and trailhere's an way to ensure you get it right ... use the following equations

where
Offset-- Centerline of top of steering neck to centerline of top of fork tubes.
Rake-- The angle in degrees of the steering neck from the vertical.
Fork Length-- The distance between the top of the fork tubes to the centerline of the axle.
Diameter of the front tire.
Diameter of the rear tire.
Trail: Distance defined by vertical line from axle to ground and intersect of centerline of steering neck and ground.
Raked Triple Trees-- In order to bring trail figures back into line, triple trees with raked steering stems can be used. Expressed in degrees. Usually adjustable in 3, 5, and 7 degrees of rake.
Tire Diameter Formula: If you do not know a certain tire diameter use the following formula:
Diam Inches = Rim Diam Inches + [ (2 x Aspect Ratio x Section Width) / 25.4]
Example: 200/55R18 Tire:
26.7" = 18 + [(2 x 0.55 x 200)/25.4]

If you use a section of goose-neck then you don't have to bother with trig. Plus, it will decrease your turning circle and act as suspension, too.

Got an excel sheet for this.
You want it ? -

i wouldn't know where to start but that would be fun
i have always been interested in the front end handling of bikes as a result of steerer tube angle rake and trail
can you postt it to the interwebz somewhere so i can have a lookand if it could be the Dummies guide to ...... it would be much appreciated
as i recall you used to design bikes with gazelle right ? i guess you must know all about this kind of thing
i like the front end of my gazelles sharp steering but pretty solid and not too tricky when bowling along on the flat

I'll put it somewhere.
By the way, it's from another bike company.
When I was at Gazelle, I didn't even have a typewriter.(and as we say in NL: cat was still written with "un". Actually, we say KAT was written with a U, but that's not so easy to understand for most of you).

Had a nice calculator by Kogswell.com bookmarked but its coming up as account suspended.
The_Smiling_Buddha found a nice one along with a article by the much loved DW.
