* 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 RD25-38T rim=633mm-38mm*2+3.5mm*2=564mm
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 RD25-38T rim is 564mm+3mm*2=570mm
A: Rim nipple bed thickness (=3.5mm)
B: Length of nipple head (2.5mm~3mm generally)
We will reply you within 24h after received your inquiry
