 Undulating Gravel Carbon Rims Features


- URD rims are now available only in disc brake version, 24 spoke holes, designed for cyclocross and gravel riding.

- In the deeper areas of each spoke hole, the rim is reinforced with special materials to enhance the rim's strength and rigidity.

- Rims profile fluctuates up and down by 5 mm, allowing cyclists to achieve better aero performance and crosswind stability. 

- Hook and hookless optional: Hook rims can perform well at lower tire pressure and can be slightly easier to mount and remove tires from, reduce rolling resistance and improve speed.Hookless rims have no weak points at the hooks where a rim can bend or break. Ultimately, the choice between hooked and hookless rims will depend on your personal riding style and preferences.

* ERD Calculate
ERD is short for effective rim diameter, it is the maximum distance that spokes bridge going from one end of the rim to another.
How do we calculate the ERD of our rims? Below are calculation equation and sketch for your reference:

URD rims ERD calculate

ERD=Rim outer diameter-(rim depth)*2+(Rim nipple bed thickness)*2

For example

ERD of UCX30-340-SL  rim=633mm-40mm*2+3.5mm*2=560mm
Most people prefer ERD including the length of the nipple head. 
However, customers may use different nipples and components for building. 
Please add the length of the nipple head (2.5mm~3mm generally) for your spoke calculation. 
If the length of the nipple head is 3mm, then ERD of your UCX30-340-SL rim is 560mm+3mm*2=566mm

A: Rim nipple bed thickness (=3.5mm)
B: Length of nipple head (2.5mm~3mm generally)
