I am trying to install an LG1 onto my stinky primo and running into some issues. The ICSG guide that bolts behind the bb cup can't get spaced out enough for the top guide to run clean on the chainring. If I space it out enough for the guide to work, the crank rubs on the guide mount. If I get the guide mount not to rub, the chainguide keeps kicking the chain off. Anyone installed one of these?
