Cheap and fat, a bit like me :-)
Close. Alpine IIIs, obviously, but Shimano hubs. HB-T780 front and HB-M758 rear. The T780 is from the Trekking range, and has a fatter axle than the road hubs for extra stiffness. M758 is a 15mm axle 6-bolt disc hub which will provide a dishless rear wheel once I've shifted it right by 5mm to provide the correct chain line, again the fat axle made me choose it over the more typical M756. I've just been toying with a Hope Pro2 20mm hub, but went back to the Shimano as it has wider flange spacing (59.1mm vs. 53mm). It doesn't hurt that it's also £20 cheaper. 20mm aluminium axle would have been nice, steel 15mm will be strong enough but heavy. Novatec track hubs are 55mm, also with smaller flanges than the Shimano and less than a quarter of the axle stiffness.
Choosing a bolt on sprocket does mean the chainring is going to be a proper dinner plate, looking at 64/16 for 106", with the option to go down to 64/17 for 100" if we need a bit more spin*.
