I have the Zipp XPLR on my Palta. Its a 1x Di2 setup which incorporates the remote satellite shift buttons and handlebar mounted junction A with TRP's Hylex RS discs.
The XPLR bar has many similarities to Zipps compact SS bar...and the rearward sweep adds a slightly more upright position compared to a straighter bar. Highly recommend!
