Shimano Dura-Ace Di2 9070 – first ride review

The new four-arm chainring bolt circle is not radially symmetric. Instead, Shimano says the arms are more aligned with how forces are transmitted during the pedal stroke, adding more material where it's needed and removing it where it isn't. Replacement chainrings will almost certainly be very expensive
