Carbon rim series for e-bike is approved!!!
If you are a heavier rider (not exceed 120kg/265lb) or for really rugged terrain aggressively, this rim series is also a perfect fit.
More carbon fiber materials are added to the inner layer for whole rim and the area around spoke hole.
Applying the latest lay-up and manufacturing technology to make the rims stronger, but also eliminate excessive materials to save weight.
Such e-bike specific MTB carbon rims are very strong, stiff and durable.
Asymmetric design helps to make wheels with more even spoke tension between drive side and non-drive side. On the one hand, it makes wheels 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.
29 inch mtb carbon rims are optional in 30//31/32/34mm inner width, to meet different tire width from 29*2.25''-3.0''.
If go with mullet configuration or looking for smaller size wheels, the 650b/27.5inch rim is also available. Working well with 650b*2.3''-2.8'' tire both on tube and tubeless.

Sectional Drawing
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 PMC937-EN rim=633mm-18mm*2+3mm*2=603mm
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 PMC937-EN rim is 603mm+3mm*2=609mm
A: Rim nipple bed thickness (=3mm)
B: Length of nipple cap (2.5mm~3mm generally)

Carbon Fiber Material Premium Toray T700 carbon fiber are used in our carbon rims. Besides, applying latest lay-up and manufacturing technology to make the rims stronger, but also eliminate excessive materials to save weight. Combining with stable resin system to make consistent quality and durable e-mountain bike carbon rims.

Asymmetric Design
Asymmetric design mtb rims help to make wheelset with more even spoke tension between drive side and non-drive side. Carbon e-bike 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 ebike 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).
