Hello,

Apologies for what is surely a dumb question, but my googlefu has failed me.

I’m new to Di2, using the SW-R9150 as a basebar shifter and the R9160 as a bar end shifter.

I’ve set the shift mode to snycho shift, which is working as designed using the 9160.

However, the 9150 shifters control the big ring only.

My objective is for both sets of shifters to synchro shift. Any suggestions regarding the setting to correct this?

Scott
