Here I go again with carbon frame issues. I'm hoping I can get some suggestions on how to clamp my Giant Defy Advanced 2 to a repair stand. Defy Advanced 2 (2009) - Bikes | Giant Bicycles | United States Gaint sells a seat post clamp adaptor that is supposed to be used whenever clamping to a stand, but I was told by my LBS that I really don't need one. If I buy a repair stand from them, they said they would show me how to clamp my bike to it, but I can get a nice stand cheap from Performance Bike. I would think that I could clamp directly to the seat post, front to back, not side to side. You would think that, like an egg, it is strongest at it's longest points, not side to side. I cant imagine why that adaptor tool would be needed. Any suggestions would be greatly appreciated.
