Warnings

info mixed-electronic-build — Shifting is electronic, but the lowest-level shifting component we can name is 105, a mechanical group. This is not a 105 groupset and not an electronic 105 either; treat the family as the level of the build, not its actuation.
info mixed-groupset — Not a uniform groupset: {"shifters":"Ultegra Di2","rearDerailleur":"Ultegra Di2","frontDerailleur":"105","crank":"Ultegra","cassette":"105"}. Ranked on the shifting level, with a penalty.
