DESCRIPTION

With no shortage of carbon bike road rims in the market, ProX has launched unique rim Undulating Road Disc (URD450). As the name suggests, such disc carbon road rim is with varying depth. Measured from spoke hole area, the rim is with 50mm depth and in between it drops to 45mm. This mid-depth profiles wave up and down 5mm for better aero performance and crosswind stability. It allow the riders to handle the bike better especially in the wind. 

For the present, URD450 rim is only available in disc brake version and conventional 24 spoke holes, designed for road riding use. The rim is specific reinforced to each spoke hole drilling in the deeper area to increase rim strength and stiffness as well.

This 45-50mm deep rim measures 19mm inside and 25mm outside. 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.

ProX decal/logo is offered for free as following picture. The decal will be applied on the rim and do the matte or glossy finish according to customers’ preference. You can choose either with such gold ProX decal or simply without decal (UD black matte or UD black glossy finish).

ProX undulating road disc carbon rims features
Normal version 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.

Both standard weight version and super light weight versions are optional for URD450.

Standard weight version (URD450) 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 (URD450-SL) carbon rim is made from premium Toray T700+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 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.

Wider Inner Width

Wider Inner Width

Wider 19mm 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.

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. 

Bead Lock

Bead Lock

There are small ridges on both side of rim channel called “bead lock”, which makes it easy for tubeless tire inflation.

Together with hooked bead to well lock the tire, prevent it from blowing out.

Tubeless Ready

Tubeless Ready

Tubeless tire is getting popular in carbon road 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.
