Black Diamond hubs are the true pinnacle of modern engineering and cnc capabilities. We use best possible materials and technique to bring what we think one of the most reliable and finesse hubset ever created. We bring you luxury and uniqueness at reasonable price.
Hubs are designed to meet demands from competitive XC racing to aggresive Enduro riding style. No weight restriction.
Huge, heavy duty 17x30x7 (6903) ABEC 5 Enduro 2RS cartridge bearings with graphite retainer cages for durability. 4 of them in the rear and 2 up front. Bigger bearings roll smoother and can withstand much higher loads. Our bearings are on average 60g heavier per set than small bearings installed in other very light hubs. 6903 bearing has 450kg of dynamic load capacity. That is 2x more than average smaller bearing mounted in super light hubs. Fear no more of wheel durability when riding big drops.
BEARING PRELOAD SYSTEM
External bearing preload nut in both hubs will keep bearings in optimal condition. Even the most precise machining will not compensate for some assembly stresses caused by lacing the hub. Hence the need for such system to ensure that bearings will work in optimal preload. This preload system requires a special BPS key which can be purchased from here.
Hubs are factory assembled in QR15. These are by far most common. If you require however to convert them to QR5, please choose additionally a converting kit. Front requires “axle and endcaps” kit and rear only endcaps. All hubs are 32H.
