DESCRIPTION

ProX Own Mould ProX 21DB Disc Wheels - Cheap Price Carbon Wheels for Amateur Riders

Considering the cost of DT Swiss hubs increases quickly, and lead time is getting longer and longer, ProX has developed our own mould disc brake hubs (called ProX 21DB Disc, only 372g/pair!). 

ProX 21DB road disc brake hubs are designed with 3-pawl freehub system, featuring J-bend and regular steel bearings. In addition, 21DB hubs can be made with your customized logo (either etch logo or make stickers). So it will become your own brand hubs!

ProX provides two width option for our 21DB disc brake carbon road 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.


ProX offers the wheels options for both types of hub--straight pull and J- bend. 

Spoke Replacement
If replace the spokes on the J-bend hub, you need to remove the cassette first and make the spoke through the hub flange. One of the big advantages of straight pull version is easy to replace them. If straight pull wheel is optimised correctly, then you can change any spoke with the wheel still on the bike.   
Spoke Strength
Some riders prefer the straight pull spoke. Because they believe the J bend does add another possible weak point on spoke’s head. However it makes almost no difference at all since the weak point of the spoke isn’t at the head. With our current warranty cases, they nearly always break somewhere else first if happens.
Spoke Availability
Bike shops sometimes don’t keep straight pull spokes in stock due to various brands and length required. For standard J-bend spoke, they’re more widely available and bike shops will have some in stock. Recommend to take some spare straight pull spokes while buying wheels. 
Wheels Lacing Pattern
One of the possible disadvantage of straight pull version is that the lacing pattern can't be changed. For example, it's possible to change between 2 cross and 3 cross lacing pattern. For straight pull hub, the spoke direction is pre-set and lacing pattern is already pre-determined by straight pull properties.  



The straight pull hub will be 17g/pair lighter than J bend hub. Head to the straight pull 98DB clincher wheels if you are looking for lighter wheels.

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

Inner Width

Relatively narrow 18mm inner width and wide 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 own mould 21DB road hubs are used. High quality hubs with cheap price.

21DB road disc brake hubs are designed with 3-pawl freehub system with regular steel bearings.
