In a number of the threads I have seen that RG owners have put on taller bars using the stock cables. If I remember correctly up to 10" to 12". I have checked my local dealers and found that they advise that the stock cables wont go that high. They estimate 1" to 2" from stock. Are they full of it? I just got an 11 RG and am interested in going higher (I am 6-4). Any help is appreciated.
