DESCRIPTION

ProX C66DB Ultra Light Road Bike Wheels With Carbon Spokes - Premium Carbon Wheels For Racing

The new ProX C66DB disc brake road carbon wheels feature cool and unique carbon spokes (only 2.9g/pc!). 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. More than anything, the carbon spoke provides both higher stiffness and better fatigue life compared to the traditional steel spokes.

ultra light road wheels with carbon spokes

ProX C66DB road disc brake hubs are with straight pull spoke system, with 2:1 (that is 14:7) spoke ratio for both front and rear wheel. 2:1 spoke ratio provides better strength balance between drive side and non-drive side. The hub shell is made of premium #7075 aluminum alloy, and the weight of hub is only 300g/pair.

Hubs are designed with 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.

Ceramic bearings are rounder, smoother and with more uniform size. In that case, the friction is reduced and that can contribute more energy to the wheels. Ceramic bearing is also harder than steel bearings (up to 30%), which improves durability, and they also don’t rust for less maintenance.

In addition, C66DB hubs can be made with your customized logo (either etch logo or make stickers). So it will become your own brand hubs!

ProX C66DB hubs with ceramic bearings

ProX provides two width option for our C66DB disc brake carbon road wheels. That is, 28mm width carbon clincher rims, and 25mm width carbon rims clincher.

The 28mm width rim series (model PRD28) is with 28mm outer (21mm inner) width.

For such wide road rims, the optimized aerodynamics tire size is 700*28C. If you plan to use 28C (or wider) tire, PRD28 rim series is recommended.

The 25mm width rim series (model PRD25) is with 25mm outer (18mm inner) width.

For such wide road rims, the optimized aerodynamics tire size is 700*25C. If you plan to use 25C tire, PRD25 rim series is recommended. 

The carbon spoke wheels are priced from USD 509/pair.

TECHNOLOGY
Carbon Fiber Material

Carbon Fiber Material

Premium Toray T700 + T800 carbon fiber are used in our carbon rims. 

Combining with stable resin system to make consistent quality and light weight carbon fiber bike rims.

Light Weight

Light Weight

By using well designed lay-up structure, mixing Toray T700 and T800 carbon prepreg, light weight carbon rims are created.

Excessive materials are eliminated to save weight, while extra materials are added around spoke hole for reinforcement.

So, light weight is achieved without compromise in strength or stiffness.

Narrow Inner Width

Narrow Inner Width

Relatively narrow 18mm/21mm inner width, make it possible to fit multiple sizes of tire.

Normally road tire size 700x25C and 700x28C are recommended (also fit other wider tires).

Aero U Shape

Aero U Shape

Wide U Shape carbon road rims are more aerodynamic than traditional V Shape carbon road rims. 

It is also of better stiffness and strength. 

Tubeless Ready

Tubeless Ready

Tubeless tire is getting popular in road bicycle wheels thanks to its better traction, lower rolling resistance and better riding comfort.

All our carbon clincher rims are tubeless ready (also fit normal tube tires).

Optimized anti-burp bump design provides easy tire mounting, dismounting, as well as air inflation. 

Road Disc Brake

Road Disc Brake

Road disc brake provides more sensitive and precise braking performance than rim brake.

Carbon fiber road bike rims designed specifically for disc brake use, no brake track. No “burning rim” worries during braking.

Specific carbon prepreg lay-up design for disc brake rims, longer durability and lighter weight.

Hand Built

Hand Built

All our bicycle carbon wheels are hand built by experienced mechanician.
