I wondered if he meant seatpost? Not seat tube. As some people have an aversion to layback thomsons – though they tend to not see through the fact that so long as the dots join up right, sometimes a steep lower seat tube, and a slacker top bit can help in some areas, like tyre clearance and vertical compliance in the saddle. Still.
I think it's bloody lovely. That 44mm ID cup looks great in a Ti frame – I still think it's a bit big in steel, but it's a standard and it's out there and that's great.
And 150 back ends with 83mm BB's – that's ace too – A powerful move away from the roadie inspired 68/73/130/135 standard. The only thing is that some people will probably moan about increase Q-factor and that 'riding a horse' feel – I've only ridden 83mm cranks on bikes I stand up on most of the time – is it a problem putting miles sat down on those Jon?
