These plastic shields split easily and trap dirt, leading to premature creaking. \u003cb data-path-to-node=\"11,15\" data-index-in-node=\"285\"\u003eThe Enduro MR2437 features a dedicated 24mm inner diameter machined straight into the steel ring\u003c\/b\u003e, allowing the crank spindle to slide directly against the inner metal race. This provides a vastly stiffer interface, runs significantly quieter, and eliminates loose components.\u003c\/p\u003e\n\u003cp data-path-to-node=\"11,16\"\u003e\u003cb data-path-to-node=\"11,16\" data-index-in-node=\"0\"\u003eWhy should I choose a stainless steel bottom bracket bearing over standard steel?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"11,17\"\u003eYour bottom bracket sits at the absolute lowest point of your bicycle frame, meaning it acts as a collection point for water running down your seat tube, heavy tire spray, and corrosive mud grit.
