I know there's a reason SRAM/Shimano/Box are the big 3 of gearing, and as much as I want to run one of these groups, I also have many projects around the house that need/must be done. I was reading about that small company, MicroShift, and their Advent group, and noticed they offer an 11-42 9speed cog group for a low, low investment. I figure what's the harm in trying? Am I that stupid, or that cheap, or a combo of both??
