The UCI seem to going over the top with their autocratic behaviour. Has any of them ever ridden a bike in anger? In the TT position, it may be neccessary to lower the front of the saddle a notch to relieve the pressure for comfort and medical reasons (as Cadel Evans commented). I guess a saddle manufacturer will now produce a saddle with a rubber insertion that allows the saddle to drop slightly under the riders weight, which will make a mockery of this stupid regulation. That is untill the UCI realise and ban the saddle too. I also think, the disqualification of Cavendish and Hushovd was over zealous.
