I have a new Orbea Onix bike. It is all carbon and I have a carbon seat post. I am concerned about where to clamp onto the bike with a repair stand. I am worried about damaging the frame or the seat post. What is the best and safest way to clamp a bike? I have even thought about making my own stand that would the top tube would rest on both at the front and the back. Am I just being paranoid or do I have to be extra carefull?
