Learn how to install a new threaded euro bb on your bike with loose cranks. When customers call our bike shop they may describe this as a loose pedal, pedal wobble or loose bearings. If only the crank arm is loose and not the axle you probably need a new crank arm. These arms are replaced because the square taper becomes rounded due to pedaling while its loose. A rounded crank arm will keep loosening up on rides and need replacement. This BB repair is most common on low priced mountain and road bikes because of the loose ball bearings and low end parts used. I would call this repair somewhat advanced, and it requires several specialty tools. Owner/Mechanic has over 40 years experience in bike repair. Watch and learn how to repair your own bicycle.
