I am quite content with my purchase a few years ago of the 250 ml bottles. If I have to buy another pair of 250ml bottles later, I will consider myself fortunate to still be rolling along at that age. At that time I will be happy to buy another pair of bottles.
I stand with George and John. I'd be delighted to be cycling at that age, and to live in a place cycling is still possible. Not off-topic at all: I remember when we used to cycle in the dark after dinner on main roads that today only the stupid and the reckless would go on.
And with Geo: for the fifty or sixty Euro that my next ten years' worth of oil cost, you can buy maybe half a Brooks saddle, and you'd pay more than that for a headset that you know will last ten years, or for a bottom bracket that you know
won't last ten years.
I think that oil is cheap, given the fact that Bernd Rohloff probably keeps up with modern chemistry and availabilities and agonizes over the changing formulation of his oil. Rather him (and George) than me, because, as the Chemistry teacher said after I blew the windows out of a wing of the school that had stood since time immemorial, "Jute, I'll thank you to stick to throwing ink bombs from the clock tower into the quad."
In any event, it seems a small price to pay for what is in effect an extended guarantee of the most expensive component on the bike.
