I'm perusing the UCI rulebook and I am not seeing any regulations WRT to the angle of the elbows in either direction. In the past I believe the max angle was 120 degrees but I'm not seeing it. Is there a reg I am missing? Is there a minimum angle? The only thing I am seeing is a max length of the extensions.

USACycling has the 120 degree angle in its UCI explainations http://www.usacycling.org/forms/uci/UCIBicycleRegulations.pdf

And in UCI 1.3.023
"For the track and road competitions covered by the first paragraph, the distance of 75 cm may be
increased to 80 cm to the extent that this is required for morphological reasons; «morphological reasons
» should be taken as meaning anything regarding the size or length of the rider's body parts. A
rider who, for this reason, considers that he needs to make use of a distance between 75 and 80 cm
must inform the commissaires' panel at the moment that he presents his licence. In such cases the
commissaires' panel may carry out the following test: ensuring that the angle between the forearm and
upper arm does not exceed 120° when the rider is in a racing position."
