Hello, I have a Cervelo S3 with an aero shaped seatpost. What are people using for rear lights in these situations? Thanks for any suggestions.

Garmin Varia would work. It has mounts for aero seat posts. You get that sweet sweet radar too.

The Lezyne rear strip drive models fit aero posts. I had one on my S-Series post too. Can’t really tell from the photos but there a sharp cutout in the back of it that holds it in place on wedge post shapes, and a more rounded general outer zone that means it also fits round posts. Bike …

I loved it enough to move it over to my Masi Evoluzione (regular seat post)… And then bought more to put on my my gravel and TT bikes (Trek Speed Concept, which also has an aero pos…

One more skeptical convert to the pricey (~$200) Garmin Varia. It transforms the experience on shoulder-less rural roads with light traffic – where I ride a lot. It reduces overall stress enough to be well worth extra cost – but I had to try it to believe it. If I were mostly in urban traffic, pro…

I love my See.Sense Ace, haven’t tried the aero mount but it looks like it would be effective.
