I got my very first CF saddle post and saddle with CF rails. Over the week I've been tweaking my saddle position but realized that it slowly slips after every ride.
Because of the front clamp position I cannot torque it properly. Instead I set the bolt length and tighten the rear bolt to about 5.2nm.
Should I increase the torque? Or can I use the carbon seatpost paste on the saddle rails? Looking for ideas on how to keep this from sliding around.

Do you have carbon paste on it?
Ok I’ll get some and try it out. I thought that was only for seatposts. Thanks!
I am betting the paste answer is the right one, but I also was wondering, is the part just under the rails symmetrical? Like if you rotate it 180 degrees will it still be positioned the same? In the back it is positioned right at the clamp, but on the front it is a lot further back.
I’ve also used a small piece of high quality tape (gaffers in my case) on the rails to increase the friction coefficient).
If your front screw isn’t tight it’ll slip until the screws equalise. I bet if you checked the rear screw with your torque wrench it’ll be below what you set it to
If you’ve got a normal L Allen key that fits your front screw, tighten both screws to what feels tight, then use the torque wrench to check what torque you got to on the rear screw. Tighten till desired torque is achieved. Does that make sense?
