Trek Speed Concept rear light

Anyone with a new Speed Concept find a good tail light / mount you like? For their other bikes, Trek has a mount directly on the seat where you can add a light. On the TT bike however, the mounting adaptors are too wide and made for bottle cages instead.

The seat post is too wide for a standard clamp. Any ideas? Thanks!

I have a Garmin varia radar and light in one. I mount it upside down to the left chainstay as close to the frame as possible using one of the rubber gaskets that came with the light. It works well enough to alert me about cars, so I assume the light can be seen also.

I have the new SC as well, and it looks like they have a light mount adapter for the seatpost, but I can’t find this part or any info anywhere on their site. It looks like you can only mount their lights on it (the Trek search is terrible for finding parts). Is this what you are referring to? I was curious about it.

Here is the part number: W5263880

Thanks Aaron - that looks great! I’m heading into my local Trek shop this morning. I’ll ask if they can order it.

Glad to help, let me know how it goes, I may order one as well, I like to keep the back end nice and tidy.

i too have this attachment and it’s perfect.

I have the old mount that goes around the seatpost. It’s yours if you want. That is assuming it works for the new one…. Just pay for shipping.

Message me and I’ll show u what I do.
