What is crank check?

A crank check is a bicycle maintenance procedure that assesses the condition and tightness of the crankset, which connects the pedals to the bike's drivetrain. This check typically involves inspecting for any play or movement in the crank arms, ensuring that the crank bolts are securely tightened, and examining the bottom bracket for wear or damage. Performing a crank check helps ensure optimal pedaling efficiency and safety while riding. Regular checks are essential for maintaining the overall performance of the bike.
