I've read a handful of reports that seem to suggest the Nashbar road cranks don't shift particularly well (as compared to 105 or Rival) and that the chainrings wear somewhat quickly. Plus, they require an ISIS bottom bracket which I consider a dead-end technology. If you're happy with 2200 or Sora quality, I'm sure they're fine. If you're discerning enough to buy a Force gruppo, however, you may want something with better longevity and shifting...
