Like bacon-flavored donuts, the Alfine Di2 delivers something you may not have thought you needed, but now probably want: internal electronic shifting. A battery in the seat post provides power to the shifter, hub and a small bar-mounted display tells you what gear you’re in and how much juice is left–when you’re out, just plug it in. The 11-speed Di2 should be available this fall, with a price TBD.
