DESCRIPTION

PRV25-C (ProX Road Rim-brake 25mm width clincher) carbon rims are equipped with high TG resin brake surface (with small grooves on the surface). 

Such high TG 3K grooved brake surface is able to bear higher temperature while braking, and the heat can be eliminated sooner, which makes our carbon rims more durable. 

- Small grooves provide more friction, less lever force is needed, and the braking distance can be shorten for about 30%.

- Small grooves make water clearance easier, improve the performance in wet condition.

- Reduce noise, avoid squeal during braking.   

Such upgraded brake surface greatly improves the service life of our rim-brake carbon rims. We offer 2 years' quality warranty for all our carbon bike rims.

(In fact, most riders have been used our carbon rims much longer than 2 years.)

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 PRV25-38C rim=633mm-38mm*2+3.5mm*2=564mm

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 PRV25-38C rim is 564mm+3mm*2=570mm


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

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

Optimized for road tire size 700x25C and 700x28C (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 rim brake 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. 

Rim Brake

Rim Brake

Carbon road bike rim designed with high TG brake track for rim brake use. Unique looking small grooves on brake surface.

Small grooves provide more friction, shorten braking distance up to 30%. Faster water clearance, better performance in wet condition.

Small grooves also help to eliminate braking heat faster, better protect the rim in long descending. 

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.
