For my training bike, I wanted to hold the Garmin Varia Radar/Light combo with the “transition hook” that doubles as a bracket so secure my single and double BTS systems. So I made a new variation. I rely on a 3rd party (injection molded) Garmin interface for safety (instead of a 3D printed bit):


It only works with the non-camera version of the radar light and the angle is fixed at 17.5 deg from the “channel” in the saddle tail so that the radar is close to vertical for my ~4.5 deg saddle tilt. Here it is mounted in combination with the single BTS mount:

With the single BTS mount you need a small index finger to activate the power button of the light, or simply rotate the radar in the quarter-turn mount a bit to power on/off, then put it back in position.
With the side-by-side BTS, the relief in the Carbon Fiber plate provides direct access to the power button.
Here is is on my “mule” / training bike:


The round relief under the bracket can still act as a “transition hook” to rack the bike in a triathlon transition (like the picture below, taken with the standard hook):

… but I would not recommend using both the radar AND racking the bike like this: unless you lift the bike much higher when pulling the bike off the rack, chances are you knock off the light and maybe damage its mounting interface in the process.
I made this for myself, but if someone’s interested just contact me and we’ll figure something out 🙂
Otherwise, some more pics 🙂




Note: it’s not meant to be used as a ‘standalone’ – the threaded inserts are tilted to match the axis of the screws from my BTS systems (7 deg off vertical).
