Frequently asked questions

Will Sentry Aero fit an aero seatpost?

Yes. Sentry Aero is specifically designed to work with aero seatposts as well as standard seatposts.

Why choose Sentry Aero over another NiteRider taillight?

Choose Sentry Aero when seatpost shape and a low-profile road setup matter. It combines aero-post compatibility, 260 lumens, and 260-degree visibility in a 65-gram light.

Is Sentry Aero only for triathlon bikes?

No. It works well for road and triathlon bikes, particularly when an aero seatpost makes conventional rear-light mounting awkward.

How long does the Sentry Aero battery last?

Runtime ranges from approximately 4.5 hours on Steady High to 30 hours on Steady Low, depending on the mode you choose.
