I have a 2108 Giant Contend SL2 Disc w/Hydraulic brakes. I am wanting to put handlebar extensions on it. But due to the unit on the handlebar for the hydraulic brakes and with the cables are tight fit, I was told by my local Giant dealer it cannot be done. And I have also contact another Giant dealer in another city close to me, and no answer back ( been a week as of this post). And I have not seen ANYTHING online about trying this. Thanks .
