CeramicSpeed's hand-built silicon nitride ceramic balls do not rust and actively crush tiny particles of trail debris that make it past the seals, maintaining a mirror-smooth track. Furthermore, housing these bearings inside a precision-threaded T47 aluminum cup set creates an exceptionally rigid, non-yielding interface. This completely stabilizes your 30mm gravel crank spindle, protects your frame shell, and ensures permanent mechanical silence.\u003c\/p\u003e\n\u003cp data-path-to-node=\"11,12\"\u003e\u003cb data-path-to-node=\"11,12\" data-index-in-node=\"0\"\u003eHow do I properly clean and maintain the bearings on this premium gravel bottom bracket?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"11,13\"\u003eTo keep your watt savings maximized season after season through dusty conditions, your bottom bracket should be serviced every 1,000 to 3,000 kilometers depending on trail grit exposure.
