Problems with ITM CX2 Angels
 

Hi I've recently bought the CX2 Angel Time Trail bars for my bike.
I've got the Dura-Ace brake levers with the gear change on the down tube. Now the people that have mounted the bike up for me have ran the brake cable outside of the handel bar tap, and they said they couldnt let it go underneath the tape.

Now if I see the pro's bike all the cables are hidden, how is it that they do that.

Secondly what is the correct bike set-up on the t.t. bike.
