The bits I ordered from CRC turned up on Saturday.
So yesterday I sorted the grips. Ergons are ridiculously easy to put on and sort. They've had an upgrade recently (compared to the somewhat older ones on the hybrid), as they now have markings on the underside to help you set the angle of the integrated bar ends. And I got the placement of the shifter pods almost spot on after moving the measurements across from the Chartres.
And armed with a decent set of cable cutters, today's task was finishing the cabling on the bike. Discovered that if one isn't careful, gear inners have a horrible tendency to fray when trying to thread them through small holes. Ergo it is much better to cut the outers with a length of wire inside them in order to keep the cut "clean". A spool of craft wire was just the ticket for this, as it is the same thickness as the gear inner, but not braided.
Did the front derailleur first. Turned out to be pretty straightforward. Even better, the original Suntour FD fitted to the bike works perfectly. The shifts are nice and clean, and take place with a very satisfying click.
Of course, I've had to guesstimate the placing of the FD clamp on the seat tube as I've yet to order the crankset, but still...
Rear derailleur was a little bit more fiddly, but still easy enough to do. I can't get shifting across the full range yet without the cable losing tension. But it's no point worrying about it, as I can't really finish sorting that until I've got the crankset and chain on anyway.
And as a result of the further fettling that will definitely be required in this department, I have left the gear inners untrimmed. They are capped with some insulating tape to stop them fraying in the mean time. I don't want to cut them to the right length until I'm absolutely sure I've got the shifting sorted.
I've pretty well much decided to go for this crankset from Spa, as it seems to be excellent bang-for-buck and comes with 160mm cranks:

Oh, and threading inner cables into the outers is like just trying to shove cooked spaghetti up a cat's bottom...
