Cyclocross/Gravel carbon rims are with relatively shallower profile but wider in width. Generally, it is something between Road and MTB rims.
ProX gravel bike carbon rims are designed with 21mm inner width, which is suitable for gravel tires with size 700*30C-50C.
Our gravel carbon rims are with 28/33/44mm height optional.
Apart from bead hook gravel rims (PCX28, PCX33, PCX44), we also provide hookless gravel rims (PZX33, PZX44), whose feature is more similar to MTB rims.
For riders who plan to use gravel bikes more like a MTB hardtail bike, and will use tubeless tire at lower tire pressure (not exceed 50psi), hookless is a good option.
For riders who plan to use gravel bike more like a Road bike, and prefer higher tire pressure (max 90psi), bead hook is recommended.
According to our sales record, PCX33 (33mm height bead hook) gravel carbon rim is most popular with our customers.

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 PCX28 rim=633mm-28mm*2+3.5mm*2=584mm
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 PCX28 rim is 584mm+3mm*2=590mm
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 gravel 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 wide 700x30C-50C gravel bike 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. Besides, the stiffness and strength are also much better.
|
 |
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 widely used in gravel bike carbon wheels thanks to its better traction, lower rolling resistance and better riding comfort. All our gravel carbon rims are tubeless ready (also fit normal tube tires), no matter bead hook or hookless model. Optimized anti-burp bump design provides easy tire mounting, dismounting, as well as air inflation. |
 |
Disc Brake
Disc brake provides more sensitive and precise
braking performance than rim brake. All our carbon gravel rims are designed 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.
|
 |
2-Year Warranty
We have strict production management system, QC and
Testing process. Our quality is always very good and reliable. For all carbon rims and carbon wheels sold by ProX, 2 years’ quality warranty is offered (starting from the date of package being signed).
