My bicycle is an older Roberts bike from the late 80's and it has cable guides on the cross tube that currently have Campy cables running through. I think it is time to replace the cables and I want the best I can get for easy shifting. Are there better cables than my current ones from Campy? This is an eight speed Record rear and a Record double up front if that makes any difference. I believe I put that gruppo on in '98. This is my second set of Campy cables. Maybe there is something better?
