Back in the 1970's and 80's pro riders would actually remove all grease from bottom brackets and wheel bearings for TT racing and shorter crits, track and road racing a like.

before everybody goes and cleans the grease off its worth mentioning they used couple of drops of a liquid lubricant (oil) for that as a substitute - apparently rolling resistance is greatly increased, unfortunately with an impact on the bearings
