morning all, thought I’d share this link. I wanted a mount to go in the saddle rails. Found this on eBay and ordered two. They work really well. I think they offer a cleaner line of sight than seatpost mounted ones. My Garmin Mount was good but always appeared to point slightly nose down but this new 3D Mount did the job. Hopefully may be of use to some of you.
Here is where I got them from
