Trek Domane+ Saddle/Taillight Mount Bracket

This mount is designed to be compatible with most standard saddle rail configurations. As long as your saddle uses standard metal rails, it should install without issue.

The mount is primarily engineered for Trek and Bontrager rear lights that utilize a standard clip-in interface. If you are using a light from another brand, check if it uses a compatible mounting system before purchasing.

No, the kit includes all the necessary hardware to get the mount secured to your saddle rails. You will only need basic hand tools, like a hex key, to tighten the bolts during installation.

Mounting to the saddle rails keeps your seat post clear, which is particularly useful if you use a dropper post or a saddle bag. It also positions the light higher up, which can improve visibility to drivers behind you.

It depends on the size and shape of your saddle bag. Because this mount sits directly under the saddle rails, a large or bulky bag may obstruct the light or make it difficult to access the mount.
