The moustache gets a bit frozen in winter. Just one thing I meant to add: I have used Simmonds screen mounts because the ones which came with the screens seemed to move (although that might have been a fault of mine0 and the Simmonds ones are rock solid. At certain speeds there is a tendency for the screen to fold back and finally rumour has it that it goes much faster without the big screen. Others can confirm or deny that. Have a good weekend.
