i have also been considering the 8" chumps, i have a SM but the america cables and even with america bars and speedmaster risers i still have cable left so i would assume no issues with the chumps and america risers? But i would not want to run them forward like that, i see people tend to do this, is that becasue they are all speedmasters with the shorter cables?
