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.

carbon wheelset disc brake UCI approved

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.

For Undulating Road Disc series rim, it is with varying depth. This design is for better aero performance and crosswind stability. It allow the riders to handle the bike better especially in the wind. 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.
Standard weight version (URD26-450, URD28-450, URD28-556) 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 (URD26-450-SL, URD28-450-SL, URD28-556-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). 
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.

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

Wider Inner Width

Wider 19mm and 21mm inner width, optimized for 700x25C and 700x28C tires (also fit even wider tires).

Wider stance for tire, easy tire mounting and dismounting. Better traction and cornering performance.

Undulating Rim Depth

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.  

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.
