DESCRIPTION

For disc brake carbon rims, it not only means simply removing the brake track, but also adjusting rim lay-up design to make it lighter so as to keep overall system weight competitive.

PRD25 series (ProX Road Disc 25mm width) carbon rims are made from Premium Toray T700 carbon fiber +  stable resin system, which is the basis for light weight.

In addition, we optimize the lay-up design, eliminate excessive materials to save weight, and add extra materials around spoke hole area for reinforcement.

Thus, our road carbon rims are light weight, but still strong and stiff.

PRD25 series carbon rims are with 25mm outer (18mm inner) width, with depth 30/38/45/50/60/80mm optional.

No matter you need shallow carbon rims for climbing or deep carbon rims for flat road riding, there is always one for you.

calculate the ERD of road rims

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 PRD25-30C rim=633mm-30mm*2+3.5mm*2=580mm

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 PRD25-30C rim is 580mm+3mm*2=586mm


A: Rim nipple bed thickness (=3.5mm)

B: Length of nipple cap (2.5mm~3mm generally)

TECHNOLOGY
Carbon Fiber Material

Carbon Fiber Material

Premium Toray T700 carbon fiber are used in our carbon rims. 

Combining with stable resin system to make consistent quality and light weight carbon road bike rims.

Narrow Inner Width

Narrow Inner Width

Relatively narrow 18mm inner width, make it possible to fit mutiple sizes of tire.

Normally road tire size 700x25C and 700x28C are recommended (also fit other wider tires).

Aero U Shape

Aero U Shape

Wide U Shape carbon road rims are more aerodynamic than traditional V Shape road bike carbon rims. 

It is also of better stiffness and strength. 

Bead Lock

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 Ready

Tubeless tire is getting popular in carbon road bike 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. 

Road Disc Brake

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

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).

Xiamen ProX Carbon Technology Co., Ltd. set up factory in Xiamen City (Fujian Province, China) in 2010. At the beginning, we manufactured all kinds of customized carbon fiber products according to customers’ demand, including carbon bike rims, carbon tubes, carbon drone body shell, etc. Since 2012, we decided to focus on main products - carbon bike rims. In 2012, we built full range carbon road rims with 20.5mm width. In 2014, we built full range carbon road rims with 23mm width. In 2015, we built full range carbon road rims with 25mm width. In 2016, we introduced product line for BMX carbon rims, as well as fatbike carbon rims. In 2018, we introduced product line for MTB carbon rims (both symmetric and asymmetric design). During the same year, we set up wheel building workshop, and started to build carbon wheelset in-house. In 2019, we added 28mm width carbon road rims into our product line (both rim brake and disc brake). Besides, we created gravel carbon rims. During the same year (2019), LightCarbon (China leading carbon frame manufacturer) visited us. After several trial order for testing, they were very satisfied with our quality. Eventually, LightCarbon invested our facotry, and we build close business relationship.
