Gents.
i’ve got an Isaac carbon jobbie on Perma-loan from a mate. It’s the bike i used recentyl in the Abingdon race. When i’m out on it, the seatpost drops about, well, about as far as it can until something stops it. This weekened it was about 4″-5″ of drop. Sometimes it’s not quite so much.
Weirdly, on the static turbo, it stays in position fine. But as soon as you go outside it drops.
I tried electrical tape at the weekend, wrapped about 5 layers round at the junction between collar and post, but sadly it still dropped. (Not that i’m blaming the post for being dropped )
Any thoughts or ideas ? Is it likely to be resolved with an Alu post instead of the current carbon one ? it’s a 27.2 if that matters.
Or maybe some very thin seoltape wrapped once to give it just a smidgen more diameter ? Or….. you tell me.
