Hi

Using BLUE loctitie should hold the bolt and also allow removing of the bolt later (blue has the least adhesive force of the loctites). Also, a bellviel or beveled washer (convex shape) would act as a lockwasher for the bolt.

I have been enjoying the highly polished microadjust Campy Super Record seatpost (NOS) for a week now. Each day I go out, when I hit a bump the seatpost adjustment manages to go out (tilt only). I see that the aluminum top piece has a helicoil installed at the factory to keep the threads from self destructing, but any good auto mechanic knows that torque often is the destroyer of fine parts. I am able to return the piece but I am reluctant to give up a find like this. I can estimate from past experience that I have applied from 15 to 20 pounds of force, or more than I would normally apply with a hex wrench to a traditional non-microadjust seat post bolt. 20 pounds of torque seems more than enough to prevent slippage without damage. Has anyone had experience with this type of one bolt design before? The new two bolt design microadjust works fine but is ugly and non classic. The older Campy seems hard to locate. Is this type a mechanical failure destined for the pages of interesting but faulty classicism? Garth Libre, still training hard in South Florida.
