Hmmm - good to know about the electrical ring. I was debating whether to power the rig that way or just stay with the Powerlet cable I've got rigged now.
Also glad to hear they can take tumbles and stay put - haven't seen one in person yet so thanks for the feedback
I'm using the BMW factory tank bag and guessing it's about 13L+/- which seems to fall between the City and GS versions.
Anyone using the GS version and a TT GPS mount on the crossbar? Wondering about clearance
