On the way in to work I had to stop (i) after 1/6 mile to adjust the front brakes since one block was rubbing slightly (ii) after 1/3 mile to adjust the right hand brake/gear lever which it turned out wasn't tightened quite enough, and (iii) after about 6 miles to tighten up the saddle, which shifted a bit, indicating it also wasn't as tight as it could be.
Not too bad, considering that I only finished things last night sometime after midnight (not the best time to be checking that everything is fully tightened!)
On the way home, I may need to adjust the saddle position slightly, the GPS angle needs to be moved by about 15°, and the lights are likely to need some tweaking (and I may move one of the rears, since I think there is a risk that the pannier is going to knock it off).
When I get home I need to put the end caps onto the bars (not that important, they just cover up the hole and keep the weather out a bit), and cut the cables short and tidy up the ends (I'll probably just solder them up). The chances are that I'll spot some other items which need doing by then as well!
