While excellent for perfect asphalt, open spokes act like a small blender on varied road surfaces—catching fine road debris, bits of grass, and wet grit, which can pack into the pulley hub and drag down your efficiency. The Alpha profile replaces spokes entirely with a smooth, solid disk. This design forces foreign material to shed instantly off the sides of the wheel without catching, ensuring continuous shifting performance over dusty tarmac and remote gravel sectors while simultaneously optimizing aerodynamics at the rear of the bike.\u003c\/p\u003e\n\u003cp data-path-to-node=\"11,12\"\u003e\u003cb data-path-to-node=\"11,12\" data-index-in-node=\"0\"\u003eIs this OSPW RS Alpha system delivered ready for in-house mechanical installation from Epic Sports?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"11,13\"\u003eYes, absolutely.
