A bike ride on rough terrain will benefit from a larger axle, while a bike ridden on smoother terrain will benefit from a smaller axle.

The rider’s preference is also a factor to consider when changing the size of the axle. A rider who wants more stability might choose a larger axle, while a rider who wants more agility might choose a smaller axle. Changing the size of the axle will also affect the suspension. A bike with a more oversized axle will have a stiffer suspension, while a bike with a smaller one will have a softer one.
