If all I was bothered with a seatpost was how quick you could put a saddle on, I’d agree with you willy. They’re a bit of a faff.
But how often do you change your saddle?
I’ve bent quite a few seatposts in the past, Thomson posts are as good as unbreakable.
And when compared with similar quality products, I don’t think they are that expensive. And I’ve never paid more than £35 for an immaculate 2nd hand one either, which I don’t think is bad at all for a product of such high quality…
Their Ubiquity? Who cares! I’m not trying to make a statement, I just want bike kit that lasts and does its job well… Hence all my bikes run Thomson’s!
