Experience unparalleled performance and durability with the Enduro Bearings MR 15307 LLB - CXD - 15x30x7 7mm MR 15307 LLU CXD 30mm ABEC 3. This high-quality component is engineered to elevate your bike’s hubs, wheels, and overall riding experience. Featuring an exclusive XD-15 Ceramic-Hybrid design, it combines cryogenically treated nitrogen steel races with Grade 3 Silicon Nitride ceramic balls, delivering exceptional resistance to corrosion and wear. The deep-groove raceways accommodate larger ceramic balls, enhancing contact area for smoother rotation and longer bearing life.
Designed with dual-lip labyrinth (LLB) seals, these bearings are expertly protected against dirt, water, and grime, ensuring consistent performance in all conditions. Filled with 90% Kluber NBU52 grease, they run smoother over time and resist washout, meaning your ride stays reliable and efficient mile after mile. Unlike other ceramic hybrids that degrade, these bearings actually improve with use as the super-hard ceramic balls polish the races, offering increasing speed and smoothness. With a limited lifetime warranty against wear and corrosion, Enduro Bearings guarantees a durable investment for serious cyclists.
Specifically crafted for hub applications, this bearing balances strength and lightness with a static load capacity of 565lbf / 2.51kN and a lightweight design at just 11.19g. Whether you’re upgrading your current setup or building a high-performance wheel, these bearings deliver precision, longevity, and consistent smoothness that stands out in any riding condition.
What makes XD-15 Ceramic-Hybrid bearings different from other ceramic bearings?
The XD-15 bearings use a unique combination of cryogenically treated nitrogen steel races and Grade 3 Silicon Nitride ceramic balls, which provide better corrosion resistance and durability. The bearings actually improve in smoothness and speed with use, unlike other ceramic hybrids.
Are these bearings suitable for all types of hubs?
This bearing size is primarily designed for hub use and is optimized for performance in those applications. It may not be compatible with all hub models, so it’s important to verify the bearing size requirements of your specific hub.
