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.

PRD28-T series (ProX Road Disc-brake 28mm width Tubular) carbon rims are made from premium Toray T700+T800 carbon fiber, plus 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.

PRD28-T series disc-brake tubular carbon rims are with 28mm width, with depth 22/33/38/44/50/55mm optional.


For rim-brake carbon rims, it is important to havebrake track with high TG and faster heat elimination. 

PRV28-T series (ProX Road Rim-brake 28mm width Tubular) carbon rims are made from premium Toray T700 carbon fiber, plus stable resin system.

Such rims are designed with high TG 3K grooved brake track, which provides more friction, shorten about 30% braking distance, faster heat elimination.

PRV28-T series rim-brake tubular carbon rims are with 28mm width, with depth 33/38/44/50/55mm optional.

calculate the ERD of road tubular 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 PRD28-22T-SL rim=633mm-22mm*2+3.5mm*2=596mm

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 PRD28-22T-SL rim is 596mm+3mm*2=602mm


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 + 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

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.

Wide 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. 

Easy Tire Mounting

Easy Tire Mounting

Small groove in the middle of tire bed, make it easy for tubular glue to be applied on.

Once tubular glue is applied, tubular tire can be mounted easily, based on the precise diamter of our rim.

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).
