ProX C52DB Disc Brake Gravel Bike Carbon Wheelset - Ratchet 36T Hub With Affordable Price
Considering the price of DT Swiss hubs increases quickly, and lead time is getting longer and longer, ProX Carbon has developed our own mould disc brake hubs (called C52DB).
Reliable quality hubs made by well-known hub manufacturer in Taiwan.
ProX C52DB disc brake hubs feature ceramic bearings by TPI brand and only 344~355g/pair with different freehub bodies. 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. The ratchet freehub system is applied on high-end hub brand hubs generally, such as DT swiss hubs.
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!
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 versions for our C52DB disc brake carbon gravel bike wheels. That is, bead hook and hookless.
For riders who plan to use gravel bikes more like a MTB hardtail bike, and will use tubeless tire at lower tire pressure (not exceed 50psi), hookless is a good option.
For riders who plan to use gravel bike more like a road bike, and prefer higher tire pressure (max 90psi), bead hook is recommended.
According to our sales record, PCX33 (33mm height bead hook) gravel carbon rim is most popular among our customers.

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 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. |
 |
Wider Inner Width Relatively wide 21mm/23mm inner width, make it possible to fit multiple sizes of tire. Normally gravel tire size 700x30C-50C are recommended.
|
 |
Aero U Shape Wide U Shape gravel bike carbon rims are more aerodynamic than traditional V Shape carbon gravel rims. It is also of better stiffness and strength. |
 |
Tubeless Ready
Tubeless tire is getting popular in 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. |
 |
Disc Brake Gravel disc brake provides more sensitive and precise braking performance than rim brake. Carbon fiber 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 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 C52DB Disc Hubs ProX own mould C52DB hubs are used. High quality hubs with good price. C52DB disc brake hubs are designed with Ratchet 36T freehub system, and with ceramic bearings inside. Such hubs can also be etched with your customized logo.

|
 |
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.
|
