Bike Parts ... Cranks
The crank is one of the most burdened parts of the bike. Aside from the strain through pedalling, the crank arms have to resist the drivers weight, even in adverse circumstances. Especially on extreme descents and leaps. the crank has to put away a multiple of the drivers weight. Modern bike cranks exhibit high stiffness, low weight and maximal stability. Because of the different standards of assembly, you can choose from a variety of different cranks for your bike and the respective purpose.
