It is the constant pedaling. Like in uphills TT they use fix gears due the constant pedaling. It works very well.
USCF 2006 rules stated on page 71, 3E 3E.2 states fixed gear bikes can be used as long as it has a front brake.
You don't use pursuit frames on the road, at least not like they used to do. I used my old one for ITT since it was a standard track bike but changed the fork to a drilled one.
Some people had rear derailleur hanger brazed on their track frames and slight relaxed angles with water bottle braze ons.
I still have mine (Panasonic Track), it was multi function bike..messenger/ cyclocross/ itt/ transportation bike.
The BT frames are made for track only and I wouldn't see them holding up well on the road.

Strength and Honor!!
