7600 or 7710 hubs in low spoke counts would be lovely for some indoor track wheels, but only sponsored riders get them. Novatecs are cheap, available and work well. Bearing replacement isn't hard with some basic tools, if you're obsessed by the drag of the rubber seals on the stock bearings you can get SKF E2 energy efficient bearings with shields rather than seals for optimal indoor performance, about £20 for 4 bearings to do a pair of hubs http://simplybearings.co.uk/shop/p7911/SKF+E260002ZC3+Energy+Efficient+Shielded+Deep+Groove+Ball+Bearing+10x26x8mm/product_info.html
