ProX Super Light Non-Paint Carbon Road Wheels Anti-Scratch Full Carbon Spoke Wheels

ProX C67DB Disc Brake Carbon Road Undulating Wheels - Super Light Carbon Spoke Road Wheels

Carbon wheels are the ultimate upgrade when you’re looking to optimize the overall riding experience. This series carbon wheels provide a stiffer ride, improved acceleration and improved aerodynamics. 

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).

The hubs are designed with thread on end caps, which makes the connection between hub body and end caps much more stable. The tightening torque we recommend for the end caps is 8N.
Front Hub: thread-in and Internal hex design, please use two hex wrenches(M12) when screwing/unscrewing the caps from front hub.

Rear Hub: thread-in, but not Internal hex design.

Please note: Due to the special wheel building tools needed for carbon spoke wheel building, as well as bigger nipple size (around 7mm diameter head, which is larger than Presta valve hole diameter 6.5mm), nipple can not be put into the rim through valve hole. It means No-External-Hole rim can not be built with carbon spokes (which comes with bigger nipple head). Thus, tubeless rim tape is a must if you intend to use tubeless tires. If you prefer No-External-Hole wheels, please choose our other carbon wheels (regular steel spokes). 

For 28mm wide rim, the varied rim depth options are 30/35mm, 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.
