im sorry if this has been answered before, but how do you mount a varia radar to a “d” seatpost with a flat back? Pretty much every major bike manufacturer makes at least one model with a d seatpost, so it’s hard to believe garmin doesn’t have an option for this yet. Using the regular mount on my specialized tarmac kinda works, but it moves around a lot and something specifically designed for a flat back post would work significantly better.
I cut a small piece of PVC pipe coupling to fit between the garmin varia mount that uses the bolt (not the rubber band). I used a 1/2" PVC coupling which has almost the perfect outside diameter to fit inside the clamp. I first sliced off a ring that had the same thickness as the clamp (around 1/4") then I cut the ring so it was only part of a circle and clamped it between the d-shaped seatpost and the garmin clamp. I'll attach some pictures, the PVC is white. I'll paint it black to make it blend in better, but I figured it would show up in these pictures much better if it was white.
I did try a 3-d printed object from thingiverse that fit the seatpost well, but it was held on with a garmin rubber band and the band tended to come out of the slot on the 3-d printed spacer, so I abandoned that approach since I feared the rubber band would come out completely and my radar would fall off.
