This should have been out this past season. Shimano would have sold boatloads. This is the long-awaited entry into the compact road crankset market. Shimano has dubbed it the R700. The suggested retail is still to be determined. All standard lenghts are being produced. The rings are the standard 50/34 but modified for better shifting performance (because of the large size difference between the two rings) AND designed to work with a standard front derailleur. No need to get a compact-specific front derailleur. I will be watching for when the rings become available. These will be a great upgrade to the current Shimano compatible compact cranksets that have been in the field for the past 1+ seasons. It's hard to beat the performance of Shimano chainrings.
