FAQ

What is the structural advantage of a 440C stainless steel bearing over a standard chromium steel bearing?

Choosing between the two options comes down strictly to balancing load capacity against environmental survival. Standard chromium steel bearings (like standard 52100 steel) are exceptionally hard and offer load ratings, but the moment water or sweat slips past the seals, the steel oxidizes rapidly, forming rust pits that ruin the smooth rolling tracks. Enduro's 440C stainless steel is deeply enriched with chromium and carbon elements, creating a self-healing anti-corrosion barrier.

Can this MR18307 bearing be used in both wheel hubs and freehub bodies?

Yes, absolutely. Because this bearing utilizes a standard caged retainer architecture to separate the balls, it spins with exceptionally low friction, making it the choice for high-speed spinning wheel hubs and freehub assemblies (frequently found in hub brands like Mavic, or custom hub axles requiring an 18mm bore).
