FAQs

Does this fit standard round seatposts?

No, this kit is specifically designed for D-shape and Aero profile seatposts.

Which Lezyne lights are supported?

This kit is compatible with the Lezyne Strip Drive and Lezyne Radar Drive rear LED light series.

Can I use these with other light brands?

The adapters are custom-molded for the mounting interfaces of Lezyne lights and are unlikely to provide a secure fit for other brands.

What is the material of the straps?

The straps are made from high-strength, weather-resistant industrial elastomers designed for long-term durability.

How do I know which adapter to use?

Visually match the curvature of the adapter to the trailing edge of your seatpost; the D-shape adapter has a flat back, while the Aero adapter is more tapered.

Troubleshooting

Light feels loose on the seatpost

Ensure the adapter is properly seated against the post and check that the mounting strap is pulled to the maximum notch setting for a tighter fit.

Adapter keeps slipping out of position

Clean the seatpost surface and the rubber contact side of the adapter with isopropyl alcohol to remove grease or road film that may reduce friction.

Pros and Cons

Ensures a rock-solid, stable mount for aerodynamic bikes

Setup, Compatibility & Care

To install, first identify the correct adapter for your seatpost profile. Place the adapter on the back of the Lezyne light mount, ensuring the concave side faces the seatpost. Wrap the heavy-duty strap around the post and hook it into the mounting clip. For optimal longevity, wipe the adapters down with a damp cloth after rides involving heavy road spray or grit. Store the unused adapter in a cool, dry place to prevent premature material degradation.
