Chill the fuck out, I was being flippant.

Perhaps my 'flippant' tone wasn't obvious in my original post.

I listened to tester's advice on tyre pressure during the tyre pressure thread months and months ago and while the thread was very dorky and I was slightly embarrassed to be involved in something so dorky (no mean feat when I'm already a dorky programmer type), tester did in fact turn out to be completely correct and the "pump to the max!!!!" advice championed by Balki was wrong.
Although in retrospect that does seem obvious.
I tried lower pressures but have gone back to about 110psi front and back, just feels quicker. I only really notice it when are below 100psi. Might just be Conti's.

is there a proper formula?
There are graphs and tables and rules of thumb. My formula is:
tyre pressure(psi) = ½[total rider + bike weight(lb)] x 23/tyre section(mm)
so for you at 185, say 210 total and 25c tyres
psi = 105 x 23/25 = 96psi
as a starting point, but you can then drop up to 10% in front and adjust both by a further ±10% according to personal preference, weather, terrain, tyre characteristics etc. Also, the best comfort, best handling and lowest rolling resistance are likely to occur at 3 different pressures, so you have to find a compromise which suits the ride you're on - for a typical 10 mile TT where comfort is irrelevant and handling is whether or not you have to get off the tribars for the turn, the compromise will be different than it is for a 6h day out in twisty country lanes.

Does anyone here know how accessible the old eurostar terminal at waterloo is?
To the public, not at all.
They're now owned by BRB Residuary (what's left of British Rail - British Rail Board Residuary). They have a page about them here:
http://www.brbr.co.uk/waterlooBRB aren't a bad bunch - I used to work underneath them for a while. I would ask them nicely what the chances are of a site visit, but bear in mind there is work currently going on to refurbish the roof, which may limit access.
I imagine physical access is through Network Rail as BRB have very few staff who are civil servants based in offices in York/London. I think it's the York lot you want as they look after structures, but they only give out a London number.

I'm after a new bearing for an FSA Orbit MX - Replacement Micro 36° / 36° Angular Bearing - Size: 36° x 36° / 41.5mm x 6.6mm
Tweeks have them for a tenner. Before I order one, is there anywhere else that would sell this cheaper? Seems like something I'd buy only to find out it's a generic part that can be bought for half the price. Wouldn't normally care so much but you can pick up the whole headset for £20 and have the rest of the parts for spares. Which is what I did last time I needed a bearing, but now I've come to need the whole headset I'm missing a bearing and don't really want to pay for another (mostly complete) headset to sit around not being used.

crosspost from chocolate thread:
does anyone know where I can buy Mary chocolates in London? The shop in Westfield has shut down so can't do that, and delivery for a small box online is £60 :o

Is there any writing on the bearing?

I'm totally confused and think I'd be best looking for a whole new headset. The box I have says Orbit MX. The tech docs from FSA say that should be 36° x 36°. Yet the new bearing that fits in the headset says TH Industries 1-1/8" ACB45° x 36° 873. I have an old, but functional bearing that I think says TH Industries 1-1/8" ACB36° x 36° on it, but that one won't fit into the cups...just a gnat's pube too large.
Just noticed that this one I have didn't come with seals either. Ho hum.

What (silver) bars would go nicely on a 1994 Colnago Master Olympic?
It currently has 3t Forma SLs, but I was hit by a car and they took the full force of the accident. They aren't visibly damaged but I'm not risking it with old alu bars.
I'm not really a fan of ergo bars anyway. Would like something period correct/that suits the bike, any ideas?

They're Alex 17s or something, heavy shitty things - I'm not worried about the pressure. I only put them to 130 because I could, needless to say they won't be staying like that. Perhaps my 'flippant' tone wasn't obvious in my original post.
