A wheelset is composed of several key components: the hub, spokes, and rim. The hub houses the axle and bearings, affecting smoothness and durability. Spokes provide structural support and can vary in material and design. The rim comes in different materials like aluminum for strength and affordability or carbon fiber for lightweight and aerodynamic advantages. Rim width and depth impact handling and aerodynamics, with wider rims offering better tire support and deeper rims enhancing aerodynamics. Compatibility with disc brakes is essential, as some rims are designed specifically to handle the additional forces from disc braking systems. The weight of the wheelset affects overall bike performance, with lighter wheels improving acceleration and climbing.
