It appears that Fairwheel did a sequential DI2 road bike but the pictures show it is the old Dura-Ace 7970 DI2 system and they had lots of glitches but in the end made it work. Hackers have complained that the new system is harder to hack ( at least the battery system due to the battery now having a chip) but the software already has more options for the shifting then the old system.
