Electronic shifters
#1
Hi
I am thinking of buying a bike with 50-34 compact with 12-32 cassette
Will I be able to use Ultegra electronic shifters with this setup?
Regards
Reg

Looks like. The rear dérailleur RD-6870-GS can handle up to 32T in the rear. The crank set FC-6800 comes as a compact version 50-34 (among others).
Something you need to consider is where to place the battery and how to run the cables if the bike does not come with Di2 form the start. Many newer frames do cater to these needs, so look at solutions on the market.

No worries. The Shimano Techdocs (ask google for the link) are quite exhaustive.
