Saddle Rail Rear Light Mount (for 50mm spaced rack mount lights)

$15.00

This adapter mounts on your saddle rails with two zip ties (included) and allows you to mount a 50mm spaced rear (dynamo) light. It’s been specifically designed to fit the Schmidt SON Rear Dynamo Light or the B+M Toplight Line Small Plus Dynamo Rear Light.

It has recesses for M5 nuts (not included) at the back for easy attachment of your light.

If your seatpost and frame support it, you can drill a hole in the top of your seatpost and route the dynamo wiring down the seatpost and out your dropper post port (or elsewhere on your seat tube). Please understand that drilling into components voids their warranty and may weaken them to the point of failure. Do this at your own risk, or get a professional bike mechanic to do this for you.

Why would you want to mount your light under your saddle you ask?

Well maybe you’ve got a sweet rear dynamo light setup attached to the rack on your bike, but these days you’re using your rack less and less… This mount unshackles that light and wiring from your rack, allowing you to then remove the rack on a whim.

Or maybe you’ve got a new bike, but want to migrate your existing dynamo light setup to it, and you’re thinking of not having a rack?

What are the downsides to mounting your light under your saddle?

If you wear long capes, coats or riding jackets with tailbone coverage they might hang over the rear of your seat and obscure the rear light. 

If you use any sort of saddle bag it might be tricky to get this mounting to play nice with the bag.

Thickness: 10mm – if you saddle is slammed all the way forward you will need to make space for it, or change your seatpost for one with less setback, to accommodate this mount.

3D Printed in ASA, which is a strong and UV Resistant plastic on a Prusa MK3S+.
