For MTB carbon rims, strength should be top priority which is essential for riders’ safety and good cycling experience.
ProX 650b MTB carbon rims PAD730-XC, PRD737-AM, PRD737-DH/EB are made from Toray T700 carbon fiber.
The model PAD730-XC-GP is made from Toray T700+T800+Graphene material to realize ultra light weight (only about 295g!). The new graphene filling technology improves strength up to 30% which is very helpful to make ultra light weight mtb carbon rims.
Apart from good material used, we optimize rim lay-up design, eliminate excessive materials to save weight, and add extra materials around spoke hole area for reinforcement.
Thus, our MTB carbon rims are strong and durable, but also with good weight.

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 PAD730-XC rim=595mm-22mm*2+3mm*2=557mm
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 PAD730-XC rim is 557mm+3mm*2=563mm
A: Rim nipple bed thickness (=3mm)
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 650b carbon rims.
|
 |
Light Weight Well designed lay-up structure, combining Toray T700 with Toray T800 carbon prepreg to make light weight carbon mtb rims 27.5er. 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. |
 |
Hookless Design Compared to bead hook rims, the sidewalls of hookless rims are thicker and stronger, providing better impact resistance. Straight bead provides more stance for tire. Tires will not be squeezed in bead as it was, which makes it less "light bulb effect". Thus, the tire/rim engagement is more stable, more difficult to be blown out under strong impact, which is important for carbon mtb rims.

 |
Tubeless Ready
Tubeless tire has been the mainstream of mtb carbon wheelset 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. |
 |
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).
