With no shortage of carbon bike road rims in the market, ProX has launched unique Undulating Road Disc series rims. As the name suggests, such carbon road rims are with varying depth. For example, measured from spoke hole area, the URD28-450 rim is with 50mm depth and in between it drops to 45mm. This mid-depth profiles wave up and down 5mm for better aero performance and crosswind stability. It allow the riders to handle the bike better especially in the wind.
ProX undulating disc brake rims are both available in conventional 24 spoke holes and 21 spoke hole(usually for 2:1 hubs), designed for road riding use. The rim is specific reinforced to each spoke hole drilling in the deeper area to increase rim strength and stiffness as well.
The rim has a hook bead design and is tubeless compatible. Tubeless tires can make a good performance at lower tire pressure for reduced rolling resistance and contribute to all out speed.
ProX decal/logo is offered for free as showed in ProX decal page. The decal will be applied on the rim and do the matte or glossy finish according to customers’ preference. You can choose either with such gold ProX decal or simply without decal (UD black matte or UD black glossy finish).
Standard weight version (without “SL” on the rim model name, such as URD28-305) carbon rim is made from Toray T700 carbon fiber which is the basis to make high strength bike carbon rims. The max rider weight limit is 120kg/265lb.
Super light weight version (with “SL” on the rim model name, such as URD28-305-SL) carbon rim is made from premium Toray T800 carbon fiber to achieve super light weight, which is more suitable for lighter weight riders (max weight limit 100kg/220lb).
Both standard weight version and super light weight versions are optional for undulating rims.
Such new aerodynamic design road disc carbon rims help to minimize wind drag and improve stability in crosswinds obviously. It will bring you a faster and more confident riding experience.
If you are interested in disc brake carbon wheels 21H(2:1 drilling) or looking forward to the wheels with carbon spokes built with our URD (undulating rim depth carbon rims), please click the link or contact us for more details.

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 URD28-305 rim=633mm-35mm*2+3.5mm*2=570mm 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 URD28-305 rim is 570mm+3mm*2=576mm A: Rim nipple bed thickness (=3.5mm) B: Length of nipple cap (2.5mm~3mm generally)

Carbon Fiber Material Premium Toray T700 and 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 700x28C tires (also fit even wider tires). Wider stance for tire, easy tire mounting and dismounting. Better traction and cornering performance.
|
 | Undulating Rim Depth The mid-depth profile waves up and down 5mm for better aero performance and crosswind stability.
Such design help to improve bike handling, bring you a faster and more confident riding experience. In addition, the stiffess and strength are also improved.
|
 | 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 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. |
 | 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.
|
 | 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). Click Warranty Policy to see more details in another page. |
