I find the most inefficient part of my setup is the guy doing the pedaling.
With exception made to racing where such margins can be the difference between comparable atheletes, so says Lance, I think worrying about the IGH being 2 -5% less efficient is akin to a clydesdale like myself insisting they must have a Durace gruppo because of the weight savings. My being 5% more efficient probably makes much more difference than whether I ride IGH or Derailleur. On a "hypothetical" 250 lb clydesdale 5% equals 12.5 lbs fewer that would be getting hauled around or 5670 grams for you weight wenies. For context a Mavic Aksium wheelset weights in at 1885 grams, and the super light Riv Roadeo is 1814 g. Just saying....
