Hi guys, I hope someone can help me with this technical problem. I was about to go for a ride on my Canyon Grail CF SL 8 and was planning to raise the saddle a little. I loosened the seatpost clamp bolt (which took an abnormal amount of force). Unfortunately, the seat post could not be pulled out. I then decided that I'd better leave it alone before I broke something else. When I sat down on it, the seat post suddenly dropped completely, so the clamp was loose enough after all, the post just jammed a little. Unfortunately, when I tried to tighten the clamp again, I realized that the screw (Torx T-25, see photo) could no longer be turned in any direction. I may have unscrewed it too far, or maybe it's jammed, but I've already used so much force to turn it that my bit has broken. Does anyone know a solution for this? I can't tighten my seat post like this and the bike is unusable.

Um. Do I see a crack that is spreading into your frame? I think you might need to contact Canyon and/or visit your local bike shop. Something seems seriously wrong and you need to get to the bottom of it. Using enough force to break a bit is worrying and you might have done some damage. Never force something like that.
