Ck your seat post, not uncommon for them to be under and oversized.
I see this all the time and it always looks like such a engineering band-aid especially on a high end bike! "one option, adam hansen uses a second seat collar. thoughts?" |

I would measure the post and look for a slightly bigger one if the paste doesn't work. They can vary quite a bit with the same nominal size.
Another option is the double clamp if the frame uses a collar. Origin8 sold them, they clamp on the frame and the post. http://www.ebay.com/itm/Origin-8-CLA...item4abbcc31ec Last edited by oliver1850; 08-17-2014 at 10:33 AM. |

A beer can shim on the inside of the post works really well.
Have one on my Pegoretti for years now. |

Assuming the sizes are all good and the bolt is not bottoming out
as mentioned by Peter, clean all the grease out and surface the inside of the clamp/seat tube with sandpaper. That works for me cause you don't have to do anything to the post itself. VF ps: try every one of these fixes and let us know the results. It shouldn't take more than 6 or 8 months! Last edited by victoryfactory; 08-17-2014 at 02:28 PM. Reason: clarity |

Partial update: I tried a different seatpost and it slipped too. My next two steps are to buy some calipers to confirm that the seat tube is, as appears, larger than stated and track down some Tacx carbon assembly paste. Fingers crossed. Frustrating.
And thank you everyone for all of your suggestions. The help is very appreciated. Last edited by Climb01742; 08-17-2014 at 05:17 PM. |

Background: I over-tightened seatpost bolt and broke it off in the seatpost cluster and had to have it backed out. My shop lubbed it up really well and put stainless steel screw in there and now I'm too much of a wuss to tighten it too much. So i took it BACK to the shop and they tightened it down to "little more than 7Nm" and sure as sh*t it slipped about 2mm after 2 hour ride last night. Can steel stretch over time ?? |

I think next steps are to wipe down and clean off grease, put some grit paste in there, and buy a torque wrench if that doesn't work i spose i could try the beer can shim |

Is it knurled or just couple of lines showing limit line? Being ‘knurled’ by shop is pretty aggressive and much deeper.

Whomever ribbed it, may have made it smaller as well...I think a smooth SP, then knurled, would fix you up.
