Recently I bought the SLC-SL frameset, which came with the Aero Carbon seatpost. As I had to readjust the saddle position on the seatpost, I had to retighten the rear hex-nut on the seatpost for the adjustments.
However, although I used a good Parktool torque wrench and tightened the rear hex-nut to 6N.m according to the Cervelo user manual, upon tightening to the recommended torque, I heard a creak sound in the seatpost area, and noticed that a section of the rear hex-nut's thread (just above the bottom base plate supporting the saddle rails) had worn off, as the black coating on the rear hex-nut's thread had been exposed to its original silver colour.
I wish to check if this is indicative that I had damaged the rear hex-nut, although I had following the recommended torque specifications exactly. I'm not exactly a bike mechanic so I have no idea if this is a cause for concern.
Thanks for any help and feedback!
