Bike parts you hate.

most forks undrilled will be to tight to fit those though

Its a clever idea--- one that I had not seen before (thanks!!!)-- but there are a number of problems beyond just tight fit.

• No room. While road forks tend to have loads of room, most of the high-end track forks are too tight. To fit the limited space the metal would have to be so thin that it would not be torsionally stable.
  
• The lateral forces from braking can under some situations be quite substantial--- anyone who has bent a brake bolt can testify to the kinds of forces can one can encounter. Any bending of the bar would block the front tire.
  
• In contrast to the example the quil, I think, would need to be much longer to extend into the steer tube and not just hang into the cast lugs
  
• Would need a fork with steel steer tube. Carbon or alu could pose some safety problems
  
• Ill suited to threaded steer tubes given the potential to deform them.
  
  

Bottom line. What at first glance appears clever and elegant.. is, I think, unfortunately a death trap ...
