Bit of an update on the trusty Salsa -- and a stuck-seatpost story to boot.
When I built the bike, I used a USE Alien aluminium post because it was nice and light. It had already been fitted to my Orange P7, Orange Sub5, and even a Giant road bike for triathlon purposes. But after a decade in humid Singapore, I realised the post was well and truly stuck. It wasn't a bother initially, as it was the right height and there were no plans to sell the bike.
But then, in the middle of a ride, the seat started to swivel slightly and it turned out the head of the seatpost was coming loose. On fiddling with it, I managed to detach it entirely. And then the stuck post became a problem.
I tried all the usual early steps: penetrating oil, gentle persuasion, etc. but it wasn't budging and it dawned that removing the post would entail its destruction. So the gentle persuasion became a bit heavier, with a pipe wrench wrapped in tape for twisting, and a couple of sharp blows with a rubber hammer. No dice.
I was reluctant to use heat or caustic soda, not to mention cutting it out, as I didn't want to damage the frame paint, so I thought freezing it with a spray made for the purpose might do. I even bought one.
Still there was no joy. Then last week, a cold front came through and temps overnight dropped to -3C -- including in the uninsulated shed housing my bikes. And the next time I had a look at the seatpost, I was able to twist it! So a quick tug or two and it was out. I'm not sure if the penetrating oil finally worked or if the cold did the trick. Probably both in combination.
What interests me now is that it's clear that Singapore's humidity caused quite a significant amount of rust between the seatpost and the frame (see pics below). Now I just want to be sure that rust is contained and doesn't spread unseen. And the replacement seatpost will be carbon fibre.
