   • 2009, Dennis Bailey, Keith Gates, Bike Repair and Maintenance For Dummies, John Wiley & Sons, →ISBN:

     Crucial to the crankset is the bottom bracket. Of all the bearings on a bike, the bottom bracket is the one that has to bear the heaviest load. Not only does the bottom bracket have to spin while you pedal, but it takes the force of all the twisting and turning that occurs during pedaling.
