Because if you allow those then people will use narrow aero setups which compromises control/safety with 20,000 wobbly cyclists.
I genuinely believe that the dangers of not being able to freewheel around or over a pothole due to riding fixed is much greater than riding a bullhorn.
I'm not saying it is dangerous but there are numerous possible, unlikely dangers
EDIT - i'll say no more, but I do understand why veldromes want to protect their surfaces, and why competitive races have strict rules... but beyond that I never cease to be amazed at the amount of people who seek to impose rules on a bunch of peole who just want to have a good time on their bikes. Obviously if you are taking the trouble to organise something and you want everyone to have white cables then that's your call, but it does surprise me.
The organisers are very safety conscious. Someone died the year I did it so you can't blame them.
