DESCRIPTION

ProX C52DB Disc Brake Carbon Road Wheels - Ratchet 36T Hub With Good Price

Considering the price of DT Swiss hubs increases quickly, and lead time is getting longer and longer, ProX has developed our own mould disc brake hubs (called C52DB). 

Reliable quality hubs made by well-known Taiwan hub manufacturer.

ProX C52DB carbon wheel with Ratchet 36T freehub system

ProX C52DB road disc brake hubs feature ceramic bearings by TPI brand and only 344~355g/pair with different freehub body. Hubs are designed with Ratchet 36T freehub system which improves power transfer efficiency, combining with ceramic bearings, the rolling resistance is minimized. Such hubs help you to shorten acceleration time and save energy. Ceramic bearings are smoother, rounder and with more uniform size. In that case, the friction is reduced and that can contribute more energy to the wheels. Ceramic bearing is also harder than steel bearings (up to 30%), which improves durability, and they also don’t rust for less maintenance.
In addition, C52DB hubs can be made with your customized logo (either etch logo or make stickers). So it will become your own brand hubs!

ProX C52DB hubs with Ratchet 36T freehub and ceramic bearings

All of the carbon bike rims will feature angled spoke holes, which will better align the spokes with hub flanges, and decrease the amount of spoke bend required when building.

ProX provides two width option for our C52DB disc brake carbon road bike wheels. That is, 28mm width carbon clincher rims, and 25mm width carbon rims clincher.

The 28mm width rim series (model PRD28) is with 28mm outer (21mm inner) width.

For such wide road rims, the optimized aerodynamics tire size is 700*28C. If you plan to use 28C (or wider) tire, PRD28 rim series is recommended.

The 25mm width rim series (model PRD25) is with 25mm outer (18mm inner) width.

For such wide road rims, the optimized aerodynamics tire size is 700*25C. If you plan to use 25C tire, PRD25 rim series is recommended.

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 fiber 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.

Narrow Inner Width

Narrow Inner Width

Relatively narrow 18mm/21mm inner width, make it possible to fit multiple 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 carbon road rims. 

It is also of better stiffness and strength. 

Tubeless Ready

Tubeless Ready

Tubeless tire is getting popular in road bicycle 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.

Hand Built

Hand Built

All our bicycle carbon wheels are hand built by experienced mechanician.

Based on customers’ demand, various choice of hubs, spokes and nipples are optional.

After wheel built, they are trued precisely at high standard (≤0.3mm) on roundness, lateral and center tolerance.

ProX Road Hubs

ProX C52DB Disc Hubs

ProX own mould C52DB road hubs are used. High quality hubs with cheap price.

C52DB road disc brake hubs are designed with Ratchet 36T freehub system, and with ceramic bearings inside.

12*100/12*142 thru-axle, with Shimano 11/12 speed or SRAM XDR 12 speed cassette body.

Pillar Spokes

Pillar Spokes

The popular Pillar PSR AERO 1423 spokes are used. 

Pillar patented cold forge technology is applied in the spoke production which increase the strength up to 20%. 

Perfect aero shape, high elasticity and low drag coefficient.

2-Year Warranty

2-Year Warranty
