- URD rims are now available only in disc brake version, with 21 and 24 spoke hole options, designed for road bike use.
In the deeper areas of each spoke hole, the rim is reinforced with special materials to enhance the rim's strength and rigidity.

* 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:
ERD=Rim outer diameter-(rim depth)*2+(Rim nipple bed thickness)*2
For example：
ERD of URD26-450 rim=633mm-50mm*2+3.5mm*2=540mm
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 URD26-450 rim is 540mm+3mm*2=546mm
A: Rim nipple bed thickness (=3.5mm)
B: Length of nipple head (2.5mm~3mm generally)
