Q: How do you stop your carbon seatpost from slipping?

A: If you Google stop carbon seatpost slip, you will come with a few different options.  One of them involves sanding the post down, so there is more friction and less chance of slipping.  I’m not a big fan of defacing my expensive bike parts, so I chose to skip that one.  Another suggestion was to change the seatpost clamp.  I prefer to just torque my current one to the recommended torque, and look for another option.

I came across some 3M Super 77 Classic and used it not only for my seatpost slipping problem, but also to mount my grips on a new carbon handlebar.  It works great!  This 3M adhesive is a high tack, high coverage, and fast drying (about 15 sec, so move quickly) spray.  I had some over-spray on my handlebar and it peeled right off.  I have also used some Goo Gone to for the grip area over-spray, but don’t be foolish . . . . TEST it out on a safe area before you use.  Materials vary, so your mileage may vary.  Read the material safety sheet at 3Ms site if you are concerned.  With that said, I have had great results, on three different bikes — much better results than hairspray.
