Add to it the lack of solid fitting to non-round/non-aero seat posts like the Specialized Pave and I just don't have confidence in the mount.
I've found a number of saddle options based on 3D printers and a bar that mounts to a Specialized SWAT mount which I've ordered. Once installed it will place the unit as high as practical and allow adjustment to pure vertical. That comes from a GoPro like mounting option. Both of those factors will lend themselves to making the most of the claimed 140 meter range.
However, these items are coming from overseas so I expect a few weeks in transit.
In the short term I cut a channel in the seat post block of the mount and threaded two zip ties for my own peace-of-mind. Good enough until my new hardware arrives.
I like the RTL510 a lot!
Zip tie modification.
My Colnago has a round seat post so when I got my Varia, I used the mount that came with it. I also have a saddlebag that takes up pretty much the entire height of the seat post. To mount mine, I had to lift my saddlebag high enough to get the radar underneath it. The problem I was having was that on bumpy roads, the saddlebag would bounce on the radar causing it to turn to the left or right of center. If the radar turned to the right, I would lose any contact with approaching cars. So my DIY solution was an old gas valve key I had lying around. The smaller O-ring that came with the Varia is used to secure the mount to saddlebag. I can easily move the Varia from bike to bike without having to have multiple mounts or remove an existing mount.
