Is it allowed to remove unnecessary components for a race?
Example: A hill climb with zero descending or significant turns.
Would it be against any rules to remove the FD and rear brake and associated cabling? I looked at the rulebook and it doesn't state that having 2 brakes is a requirement, although the UCI book does. This would save .5 to .75 pounds depending on level of components.
I'm asking mainly out of curiosity, but this also seems that it could be useful in certain situations.
