Hi all, looking for help please. I have a new Madone SL7 and wanted to add some storage for long distance tri. I was looking at the speed concept 2 box, wondering if I could fabricate a plate to allow it to connect to these screws on the rear of the seat post, but I’m not sure what the screws are for! Can anyone help please? There will be a few issues that I’ve planned to overcome like the speed concept post angle is 4degrees different, and the spacing on the mentioned bolts don’t align the box but nothing significant. I also think the box is narrow enough to sit low to the wheel as it will fit between the rear triangle.
Any advice on those bolts and suitability as I don’t want to knacker my frame!
Yes the light is temporary till I wait for my flare to be delivered!
Cheers all 👍
