If you're riding am entry-level or mid-range mountain bike and want to upgrade or replace your crank but don't want to spend a ton, the Acera crank is a nice choice. Shimano's patented Hyperdrive chianrings deliver quiet and easy shifts. And the chainrings are removable so you can clean or replace them easily (most lower quality cranksets have non-removable chainrings). And the Octalink bottom bracket (sold separately) is a real upgrade from the old square taper kind.
