another little tip: I had some cheepo replacement wheels (no-name hubs laced to a wide Alex alloy rim, cost maybe $40 each from a LBS) and the first thing I did was open them up to repack and adjust them. These hubs had ball bearings in RACES which I immediately replaced with (new grade 25) loose balls, then new grease (Finish Line) and adjustment. They spun 100% better than before...but as soon as I could afford better wheels I replaced the replacements.
