A stem (£8) and a bottom bracket (also £8) for the Poo Brown Bike. The 300EX cranks turned up and they want a 110mm rather than a 119mm. Sheldon Brown's BB database is bollix - it says 115mm for 300EX but 110mm is what you need for 46mm chainline at the outer ring, which is Shimano spec.
I've built it as a "road" 46mm fixie rather than "track" 42mm because it's never possible to get 42mm with cheap road cranks - you always need an unobtainably short BB or you have to put the ring on the inside of the spider, which makes people point and laugh. Also, 46mm matches the chainline of my proper track bike, so I can try it with those wheels if necessary, and a Miche Primato single-sided track hub respaces beautifully to 46mm if the new owner wants to upgrade.
