Ive had this Oval carbon seat post on the bike for 15 years and never had a problem.

During a servicing + fitting of a new saddle, mechanic says the seat is now tilting up and down even though
the nuts on the clamp are tightened to the max. He swears he greased the nuts and the threads aren't stripped or anything.

Been reading up on this situation where saddles tilt up and down and it seems to be happening to a lot of people...and its
always very old gear. So Im thinking it's some sort of wear and tear.

Anyway, it gave me an excuse to order a S13 from Canyon. Ive read good things s hopefully this will sort out my seat post issues.
