I have a lightweight rack on my Cannondale Uber V seat post. Is there a reason you don't like them? Is it an engineering / stress issue or ??? I have a regular seat post on my bike. Just curious.Richard N wrote: ↑Aug 02 2018 9:31amIt's all about the rear rack. If I can noodle a solid rack that doesn't just clamp on to the seat post, that might make me a convert. I'll never mount one on the stays either, I just don't like that arrangement.
Your idea for one that uses the tube is interesting.
