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 is one of the most reliable and finesse hubset ever created. We bring you luxury and uniqueness at reasonable price.

Model (Mass +/-2g):

Front: QR15 (138g), Rear: 142x12 10/11spd (268g); 142x12 XD (263g). All hubs are 32 holes only.

Color

BLACK, Racing red (Limited)

Options

Front can be converted to QR5 - new axle and endcaps required. Rear can be converted to QR135- only new endcaps required.

Material

body: cnc machined 7075 Txxx Aluminum, Freehub&ratchet: hardened rust proof steel

Finish

type II anodizing

Destination

Hubs are rated from XC to aggressive Enduro. They will also work great on CX bike. No weight limit.

Hubs are designed to meet demands from competitive XC racing to aggresive Enduro riding style. No weight restriction.

BEARINGS:

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.

FREEHUB BODY

We use hardened, rust proof steel for extreme longevity and cassette „dig in” prevention. It's almost as light as aluminium counterpart, but many times stronger. Individual cogs will not bite into freehub, even when loose. Freehub is rated for 7(dh), 9, 10 and 11(CX) speed cassettes, Sram and Shimano.

MAGNETIC RATCHET SYSTEM

This Worldwide patented mechanism is one of the most reliable out there. Instead of steel springs and pawls we use two powerful, circular magnets to push two ratchets together. All parts in this system are made out of hardened, rust proof steel for uncompromised durability. This ratchet system can tolerate mud, water and other contaminants unlike standard solutions based on pawls. We use 26 Points Of Engagement for a perfect balance between drag and durability (as more POE than that creates more drag and is more fragile for contamination). Design's greatest strength is its ability to cope with very high load. The reason for it is that you always have 26 points engaged, unlike 2-4 in pawl&spring system. Thanks to „no steel spring” design, this system can work at any temperature with unchanged repelling force on the ratchets! System we use meets great success from over 8 years on the racing field.

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.

SIMPLICITY

Ratchet system has only one moving part. Rear hub can be disassembled and cleaned by hands.

CONFIGURATION

Hubs are factory assembled in QR15, 142/12 Shimano and 142/12 XD (XX1) configuration. 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.

Dimensions for wheel building

All spoke holes are 2.5mm in diameter. Measurements are provided from center of the hub to center of the flange holes. Drilling circumference is provided from centers of the spoke holes. It is always a better idea to give such a great hubs to wheelbuilder to create wheels. You will use them a lot, so make sure they are properly laced and tensioned. Hubs drilling - 32H.

Front:
Left & Right flange drilling Ø: 56mm
Center to right flange: 28.3mm
Center to left flange(disc): 22.5mm

Rear:
Left & Right flange drilling Ø: 55.5mm
Center to right flange: 20mm
Center to left flange(disc): 34mm

Maximum spoke tension:
Front:
Disc side 120kgf +/- 10kgf
Non disc side 100kgf +/- 10kgf

Rear:
Disc side 70kgf +/- 10kgf
Drive side 120kgf +/- 10kgf
