Canyon Grizl SL7, with a seatpost that will not stay set. I’ve redone the carbon paste and re-toured the set screw multiple times, but it slipped again today on level hardpack.
Canyon support said to insert a piece of sandpaper into the seat tube, or add a shim, and/or increase torque to 7kN.
Anybody else dealing with this?

Is it slipped back down into the tube, or is the saddle just tilting forward? If it’s tilting, remove the entire seatpost, loosen the bottom bolt and put some friction paste between the halves of the seatpost, and re-tighten the bottom bolt.
This happened on mine as well. It just kept slipping, and it rubbed the finish off. I ended up selling it for a redshift seatpost and later a roval terra
I ended up placing a small rubber coated pipe clamp directly above the frame and screwed it tight. Looks ugly yes, but successfully prevents slipping for two years by now. And with a dozen of bags it’s not noticeable.
Nevertheless it’s and engineering fail. Just give me a traditional seatpost clamp.

Had the same issue. Seat eventually slipped and got stuck. Had to break the friction piece to get the seatpost out. Canyon had to send me a new piece. Whole process sucked.
Are you sure you applied enough carbon paste and torqued it to 5nm?
