Canyon Ultimate CF SL Seat Post Bolt: Torx T25 or Allen 4?

Hey everyone,

I’ve got a Canyon Ultimate CF SL 2004, and according to the manual, the bolt on the seat post clamp is supposed to be a Torx T25. However, when I used the Canyon torque wrench, it seems like it’s actually a size 4 Allen bolt, since the Torx slips but the Allen key fits perfectly. Has anyone else experienced this or knows if it’s actually an Allen or Torx bolt? Thanks for your help!
