Classified Powershift? If so, it's really promising but I can't get past the price.I saw a neat internal 2 speed rear hub that can be used with standard cassettes for more gear range. I wonder if it would be compatible with the Grail? It's not cheap but it looks like it would be worth it.
FWIW I was doing ~33mph at 105 rpm today (stock gearing and 650b wheels).
