Seatpost kept slipping in the seat tube of my 2017 T130S. Of course if you over tighten the clamp the reverb won't fully return to it's extended position. Tried carbon paste, it worked for one ride. Tonight I used a piece aluminum can as a shim, we'll see if it works...
I took it back to the shop and the mechanic fixed it by filing the anodizing off the teeth of the seatpost clamp wedges. He said the Reverb and seatpost clamps are both anodized so they cant grip each other??
