It's a pleasure to install high quality cup and cone type parts like Campagnolo Record BB's and hubs when your effort of careful, proper, assembly is rewarded with perfect performance.

It always amazes me when you can lightly swat a crankarm and watch it spin a dozen times then rock back and forth to its center, or watch a wheel spin for a minute in a stand from a gentle tug. Sealed bearings and modern seals just don't swing like that.
