Got a carbon bike with a carbon seat post and it has one of those wedge seat post clamps integrated into the frame so like the synapse and giant defy. 4mm hex bolt. Bolt isn't rounded off just yet. However, I cannot get This bolt to turn to get the seat post out. The bolt is so tight that my Allan key feels like its going to snap. Any suggestions? I've tried using gt 85 and some plus gas, but I don't think there is enough gap to penetrate this bolt. Suggestions welcomed before I end up stripping the bolt head.
Thanks
Yusuf
