The RH-CS300-RB-HG hubs are specially designed for carbon spokes, with 298±5 grams/pair light weight and Ratchet system designs, using high quality and durability Aluminum alloy 6061+7075 materials, ceramic bearings, make the complete hubs with the features of smooth rolloing, durability and high efficient power transfer, building with KOIBIKE light weight and high TG rim braking rim of R50X26TL model, make the complete wheelset weight around 1365±30g, which can be a best option for high speed road races.

Product Features and Advantages

Using Aluminum alloy of AL6061 for shell body and AL7075 for the freehub and axle, front hub weight is only 88 grams, while rear hub weight is only 291 grams.

Smooth Rolling:

The 6802 and 15267 steel or ceramic high quality and durability bearings make the hubs with smooth, low-friction, which enhances the efficient power transfer, riding experiences and longevity.

Perfect Compatibility:

Shimano HG, MSR (Microspline road), N3W (Campagnolo) and XDR (SRAM) freehubs are all available, the high-precision and machining technology ensure the hubs are compatible with the wheel's spoke count and axle type.

Special Designs for Carbon Cpokes:

The RH-CS300-RB hubs are specially designed for our CS-R38 and CS-R50 carbon spokes, which are only 3 grams/piece, the hubs also have better pull out resistance, fatigue resistance, vibration damping and durabilty advantages for carbon spoke wheelsets.

Two-to One Designs:

The rear hub is with 21 holes(14+7), 2:1 Two-to-One designs, which bring the highest level of torsional stiffness and enable the optimal transfer of power to the wheel, the Two-to-One design also reduce the unit load sustained by each spoke, which guarantee the longevity of the wheels.

OEM & ODM Services:

KOIBIKE have a 2000 square meters production line for hubs, 15+ R&D people and 10+ years production experiences for bicycle hubs and parts, who can provide professional OEM & ODM services for all kind of your requests.
