Bike again
So the Sugino 52/34 finally came, but it's moved my chainrings about 1cm right, and the old front derailleur can't reach; so I had to commute with a 34/15 top gear (the 34/13 rubs) which made for slow progress since if you spin like a little bitch you can make about 18mph.
Now, however, I know why "Tiagra" parts are named after the famous drug; the new derailleur I have bought will help me get it up (onto the 52).
A shorter BB spindle wouldn't hurt, but I have stripped BB threads and have to use the wierd "threadless" BBs that screw into themselves, which are only available in long spindle lengths unless you chase all over for a measly 5mm reduction - however since these BBs don't have any inherent left-rightness I can flip it over and fit spacers to move the right crank fairly far right.
Unavoidable increase in Q-factor (pedal separation), but the new MKS platforms (with toeclips still) are quite nice and make up for it to a degree. Kept the old cranks because I plan to build a fixed gear at some point and lower Q-factor clearly helps avoid pedal touchdown in corners on a fixie.
Still, the end result - a 34/34 low gear - should be worth the effort.

It all sounds very jolly, however.
Has it got anything to do with sleazy bars?

Er. Will you be making it out on the 23rd, then?
