For disc brake carbon rims, it not only means simply removing the brake track, but also adjusting rim lay-up design to make it lighter so as to keep overall system weight competitive.
PRD28 series (ProX Road Disc 28mm width) carbon rims are made from Premium Toray T700+T800 carbon fiber, plus stable resin system, which is the basis for light weight.
In addition, we optimize the lay-up design, eliminate excessive materials to save weight, and add extra materials around spoke hole area for reinforcement.
Thus, our carbon road rims are light weight, but still strong and stiff.
PRD28 series carbon rims are with 28mm outer (21mm inner) width, with depth 22/33/38/44/50/55mm optional.
No matter you need shallow carbon rims for climbing or deep carbon rims for flat road riding, there is always one for you.

ERD*
Effective Rim Diameter (ERD) is the maximum distance that spokes need to bridge going from one end of the rim to another. How do we calculate the ERD of our rims? The corresponding equation and a drawing is as shown:
ERD=OD-(rim depth)*2+(rim thickness)*2
For example:
ERD of PRD28-22C rim=633mm-22mm*2+3.5mm*2=596mm
Most people prefer ERD including the length of the nipple cap. However, customers may use different nipples and components for building. Please add the height of the nipple cap(2.5mm~3mm generally) for your spoke calculation. If the height of the nipple cap is 3mm, then ERD of your PRD28-22C rim is 596mm+3mm*2=602mm
A: Rim nipple bed thickness (=3.5mm)
B: Length of nipple cap (2.5mm~3mm generally)

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 road bike rims.
|
|
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. |
|
Wider Inner Width
Wider 21mm inner width, optimized for increasingly
popular 700x28C tires (also fit even wider tires). Wider stance for tire, easy tire mounting and dismounting. Better traction and cornering performance.
|
|
Aero U Shape Wide U Shape carbon road rims are more aerodynamic than traditional V Shape road bike carbon rims. It is also of better stiffness and strength.
|
|
Bead Lock There are small ridges on both side of rim channel called “bead lock”, which makes it easy for tubeless tire inflation. Together with hooked bead to well lock the tire, prevent it from blowing out.
|
|
Tubeless Ready
Tubeless tire is getting popular in road bike carbon 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 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.
