Shimano Ultegra Di2 derailleur hanger

[YMFB]

Does Shimano Ultegra Di2 derailleur hanger identify a specific part or could there be variants ?

Can I buy one on line with confidence as I don’t really have time to visit my LBS. It’s for a Cervelo S5.

Who sells them ?

thanks

A mech hanger is a mech hanger so you need one specific for your bike.

As said, "Shimano Ultegra Di2 derailleur hanger" is not a thing. All RDs (just about sfaik) are secured to the frame drop out (hanger if exists) with an M10 x 1mm fine thread screw (integral to the RD).

Thanks for all the pointers. I contacted my LBS who are a Cervelo dealer and where I bought the bike from. They have ordered one and hopefully I can pick it up in the next couple of days.
