Hi.

I just bought a 2021 Specialized Roubaix Sport, which comes with the D-shaped Pavé seat post. You will see how its back side is flat from the second picture in the following article.

The current tail light I have, the Cateye Rapid 3, doesn't fit onto it because the mounting bracket is curved for a round seat post.

Does any of you know of a tail light that fits onto the Pavé seat post? I've tried a few tail lights that I have, but they all assume to be attached to a round seat post.

Thanks in advance!
