Taillight mounts are not. Bolt a Garmin Varia to a raked post with the mount it came with and your radar ends up tilted toward the sky — scanning the treetops instead of the road behind you, and throwing its light where nobody is driving.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCut for the SL8 seatpost profile — note the SL8 post is NOT interchangeable with the SL7.\u003c\/strong\u003e The mounting angle is built into the part, so the light sits level with the ground.
