Saddle Bolt Question

Notices
Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

Saddle Bolt Question

Hey All,
What does the "7 RND" label on my saddle bolts mean? Also, from looking at this, do you know which bolt(s) I'd need to adjust to adjust the saddle tilt? I'm looking at the ones on the sides vs. the one silver bolt underneath and in the back.
Thanks!

I donít know what the label means but those are to clamp the saddle rails and adjust fore/aft. The vertical bolt in back adjusts tilt.

FWIW, though not a great angle/photo, the tilt bolt under the saddle appears might be a T25 torx

Just a guess, looking at the clamp style, the 7RND is probably saying that the clamp is only compatible with 7mm Round rails.

Yes, 7mm round vs 10mm oblong rails.

Thanks guys. I was able to adjust it using a 5mm hex.
Does the tilt angle slip over time? About 6 months ago, I was at the bike fitter and told him I felt like I was slipping off the front and he said that the nose was tilted down 1.5 mm and that it may have been bumped.
Recently my wrist started hurting and I noticed that I felt the same feeling of slipping off the front. Instead of going back to the fitter, I decided to start tinkering with it. One 360 deg turn nose up and it feels better.
Is it normal to slip over time?

Not 100% familiar with your seat, but you might try tightening the side bolts also after you get it where you like it. That might stop the movement over time. It shows the torque measurement on the side. Other than that, I don't see a locking nut or device to stop movement over time. Good luck,
