Features
The C67DB hub is made by well-known Taiwan hub manufacturer and with the reliable quality as usual. It is with straight pull spoke system and 2:1 spoke ratio (14:7) for both front and rear wheel. 2:1 spoke ratio provides better strength balance between non-drive side and drive side. Hubs are with high flanges for better lateral stiffness and handling performance. The weight of hub is only 321g/pair which is light weight. Hubs are designed with DT swiss style Ratchet 36T freehub system which improves power transfer efficiency, combining with ceramic bearings, the rolling resistance is minimized. Such hubs help you to shorten acceleration time and save energy. The unique full carbon spoke (only 2.9g/pc!) is customized which is 3.1mm wide aero bladed by default. Such carbon spokes (model CS1) is lighter but stronger than regular steel spokes. The carbon spokes look similar as regular spoke, except for the carbon fiber material and ultra light weight. The weight of our CS1 carbon spoke plus specific aluminum nipple is only 3.2g, which is about 1.8g lighter than well-known Sapim CX-Ray spoke with nipple. C67DB wheels is allowed to update to with wider carbon spokes(5.5mm width, model CS2) as shown. From wider carbon spoke, it gets more aerodynamic. The wheels weight with 5.5mm width carbon spokes is around 10g added compared wheels with 3.1mm spokes. More than anything, the carbon spoke provides both higher stiffness and better fatigue life compared to the traditional steel spokes. The max spoke tension of the carbon spoke is 528kgf according to our in-lab test, which is much higher than regular steel spokes (typically under 400kgf).
Detailed Images

For 28mm wide rim, the varied rim depth option is 45/50mm and 60/65mm .This design is for better aero performance and crosswind stability. It allow the riders to handle the bike better especially in the wind. The rim has a hook bead design and is tubeless compatible. Tubeless tires can make a good performance at lower tire pressure for reduced rolling resistance and contribute to all out speed. These super light weight carbon rims are made from premium Toray T800 carbon fiber to achieve super light weight, which is more suitable for lighter weight riders (max weight limit 100kg/220lb). Such new undulating rim depth carbon rims help to minimize wind drag and improve stability in crosswinds obviously. It will bring you a faster and more confident riding experience. We also offer Duty Free Shipping to EU countries (+UK).
