For MTB XC carbon rims, strength and weight should be both top priority which is essential for riders’ safety and good cycling experience.
PMC932-XC (ProX asymmetric mtb 29er) carbon rims are made from Toray T700 carbon fiber which is the basis to make high strength mtb carbon rims. The max rider weight limit is 120kg/265lb.
PMC932GP-XC carbon rims are made from premium Toray T700+T800+Graphene pre-preg to achieve super light weight, which is more suitable for lighter weight XC riders (max weight limit 100kg/220lb).
Furthermore, PMC932 rims feature reinforced nipple bed. As it is highlighted in below picture, the area around spoke holes are raised with extra carbon material added, which make it stronger, prevent from being pulled through by high spoke tension.
Asymmetric design helps to make wheelset with more even spoke tension between drive side and non-drive side. On the one hand, it makes wheelset stiffer since the spoke tension on non-drive side can be higher (than regular carbon wheels built with symmetric rims). On the other hand, the closer spoke tension between two sides make the wheelset more difficult to get loose after long time of use, which means less maintenance is needed.
Thus, our MTB carbon rims are light weight, but still strong and durable.

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 PMC932-XC rim=633mm-25mm*2+3mm*2=589mm 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 PMC932-XC rim is 589mm+3mm*2=595mm
B: Length of nipple cap (2.5mm~3mm generally) |

Carbon Fiber Material Premium Toray T700 + T800 carbon fiber are used in our carbon rims. Besides, advanced graphene filling technology is used in producing our super light MTB carbon rims (GP model). Combining with stable resin system to make consistent quality and light weight 29er mountain bike rims.

 |
Light Weight Graphene filling Toray T700 + T800 carbon prepreg are well combined in our lay-up structure design, to create light weight carbon bike rims. 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. |
 |
Asymmetric Design
Asymmetric design mtb rims help to make wheelset with more even spoke tension between drive side and non-drive side. Carbon mtb wheels built with asymmetric rims are of better stiffness and stability. The spoke tension on such wheelset will not get loose easily, lower frequency for re-truing is needed.
|
 |
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 mountain 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. |

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).
